Java enVironment Manager

jenv: the Java enVironment Manager

jenv is a tool for managing parallel Versions of Java Development Kits on any system, such as Linux, Mac and Windows. It provides a convenient command line interface for installing, switching, removing and listing candidates. If you have any problem, please join gitter room: https://gitter.im/linux-china/jenv

Why jenv

• Easy to manage Java versions, such as 1.6, 1.7 and 1.8
• Easy to install Java related tools, such as ant, maven, tomcat etc.
• Easy to manage candidate versions. It supports installing new version, reinstalling or uninstalling old ones
• Directory is standard and friendly to IDE
• Easy to be extended - you can setup your own jenv in your company to manage development environment
• Easy to backup your env.
• Bash completion support. Use TAB to complete command name, candidate name and version
• Multi OS support, such as Mac, Linux and Windows(Cygwin)

Installat jenv

Open your favourite terminal and enter the following:

    $ curl -L -s get.jenv.mvnsearch.org | bash

If the environment needs tweaking for jenv to be installed, the installer will prompt you accordingly and ask you to restart.

Install Java

Because I cannot redistribute Java SDK, so you should download it from http://www.oracle.com/technetwork/java/javase/downloads/index.html and install by yourself. After installation, please execute the following command:

    $ mkdir -p $HOME/.jenv/candidates/java
    $ ln -s /Library/Java/JavaVirtualMachines/jdk1.8.0_112.jdk/Contents/home $HOME/.jenv/candidates/java/1.8.0_112
    $ jenv default java 1.8.0_112

for Mac user, after you install JDK from dmg file, please execute:

$ jenv install java 1.8.0_112 system

and jenv will link the Java version automatically.

You can also install Java by http url:

$ jenv install java 1.8.0_112 http://xxxx.com/java/java-1.8.0_112.zip

Install candidates

Firstly, view all available candidates:

$ jenv all

Secondly, list available versions for the candidate, such as maven candidate:

$ jenv ls maven

Finally, install the candidate with the specified version:

$ jenv install maven 3.5.3

In your terminal, type mvn --version to check the installation.

If you want to list all installed candidates, use the following command:

$ jenv ls

For Docker user, your can use silent mode in your Dockerfile as following:

$ JENV_AUTO=true; jenv install maven 3.5.3

Update repository

The candidate's versions are maintained in the central repository. To keep updated with central repository, please use:

$ jenv repo update

Clonable development environments with jenv

You can clone your jenv between multiple hosts.

• clone your local jenv to remote host: jenv clone user@remote-host
• clone your local candidate to remote host: jenv clone candidate version user@remote-host
• clone candidate from remote host: jenv clone user@remote-host canidate version

Other Commands

• uninstall: Uninstall the candidate with the version specified, such as jenv uninstall maven 3.0.4
• reinstall: Reinstall the candidate with the version specified, such as jenv reinstall maven 3.0.5
• use: Use the candidate with the version specified, such as jenv use maven 3.0.4
• which: Check which version for candidate
• pause: Pause candidate usage
• exe: Execute script under candidate, such as jenv execute tomcat startup.sh or jenv execute tomee startup.sh
• default: Make the version as default, such as jenv default maven 3.0.4
• cd: Change directory to candidate install directory, such as jenv cd groovy
• show: Display the candidate's detailed information
• requirements: Display jenv requirements

jenvrc support

jenvrc is jenv setup file which contains candidate and the version as following:

java=1.8.0_112
maven=3.5.3

After you enter this directory, jenv will setup environment automatically. Now You can use jenvrc to setup Java environment for each of your individual projects. You can use jenv init to generate jenvrc file.

  $jenv init

Note: Line started with # means line comment.

Script Hook

All the scripts are under candidate home and invoked by jenv automatically.

• autorun.sh: executed to load current candidate
• post-install.sh: executed after install
• uninstall.sh: executed before uninstall

Install local candidates

If you want to add custom candidate into jenv, please create candidates_local under $HOME/.jenv/db/ directory and input candidate name.

$jenv add spike 0.0.1
$jenv install spike 0.0.1 [email protected]:linux-china/groovy_scripts.git

Then you can install candidate from git repository, and you can update candidate by following command:

$jenv update spike

If the candidate is absent, jenv will update all git or svn based candidates.

$jenv update

Update all git or svn based candidates.

jenv with Docker Executable Images

If you want to integrate jenv with Docker Executable Images, you can use following steps:

• create a repository in github
• create autorun.sh file to create functions for commands in Docker images:

mvn() {
    docker run --rm \
              -v $(pwd):/project \
              -w /project \
              --entrypoint mvn \
              maven:3.5.0-jdk-8 $*
}

• install candidate from github
• execute shell functions in autorun.sh

How to update jenv

Please use selfupdate command to get last version and candidate repository.

   $ jenv selfupdate

jenv IntelliJ IDEA plugin

With jenv IDEA plugin, you don't need to setup Java SDK, Maven, and so on, and jenv IDEA plugin can scan jenv directory and setup the settings in IDEA automatically. Please visit http://plugins.jetbrains.com/plugin/?idea&pluginId=7229

jenv's Issues

用 jenv 在 i686 的机器上安装 java，出现错误 可执行文件格式错误: java

jenv 在配置了 i686 的机器安装的 java 的版本为 x64 的，导致在安装完运行 java 命令后会出现

可执行文件格式错误: java

这样的错误。

i686 应当安装 x86 的包，而不是 x64 的包。

Quiet cd

Don't print messages in cd() or __jenvtool_utils_echo_green when changing directories.

As a workaround, I put this in my ~/.bashrc:

[[ -s "/Users/andrew.pennebaker/.jenv/bin/jenv-init.sh" ]] && source "/Users/andrew.pennebaker/.jenv/bin/jenv-init.sh" && source "/Users/andrew.pennebaker/.jenv/commands/completion.sh"

# Silence successful jenv messages
function __jenvtool_utils_echo_green {
   echo $'\e[32m'"$1"$'\e[00m' >/dev/null
}
cd () {
  builtin cd "$@"
  if [[ -f "${PWD}/jenvrc" ]]; then
     echo "==============jenv load ======================" >/dev/null
     while read entry
     do
       if ! __jenvtool_utils_string_contains "$entry", "#" ; then
            candidate1=`echo ${entry} | sed 's/=.*//g'`
            version1=`echo ${entry} | sed 's/.*=//g'`
            if [ -d "${JENV_DIR}/candidates/${candidate1}/${version1}" ]; then
                __jenvtool_use "${candidate1}" "${version1}"
            else
                __jenvtool_install "${candidate1}" "${version1}"
            fi
            unset candidate1
            unset version1
       fi
     done < "${PWD}/jenvrc"
  fi
}

使用source执行autorun.sh得到的$0不正确

在jenv-init.sh中使用了下面的代码来执行autorun.sh

source "${JENV_DIR}/candidates/${CANDIDATE}/current/autorun.sh"

但是使用source执行autorun.sh时，$0的值会是-bash

这样会造成一些项目的autorun.sh不能正常运行

例如maven中的autorun.sh

#!/bin/sh
app_dir=`dirname $0`
export M2_HOME="${app_dir}"

由于$0的值是-bash，所以每次登录就会提示这个错误

dirname: invalid option -- 'b'
Try `dirname --help' for more information.

可以考虑将autorun.sh中的$0都改为$BASH_SOURCE[0]

测试的Bash的版本是GNU bash, version 4.2.24(1)-release (x86_64-pc-linux-gnu)
#19 提到的应该是同一个问题

能否加入python, ruby&nodejs的支持，不知道这个能不能和rbenv一样支持插件rbenv(pyenv/nodenv)-build.
这样就不是jenv了，是allenv.

install local java should account for symlinks

When jenv copies a local java install into its directory, it is not properly copying symlinks. It copies the symlink verbatim as opposed to creating a symlink keeping relative paths intact.

Below shows this for the file cacerts

Add OpenJDK

I think it would be beneficial to add openJDK to the list of items that can be downloaded and installed.

jenv 自动提示出错

敲入 jenv <TAB> canidates
然后会出现：

Invalid command: canidates

Usage: jenv <command> <candidate> [version
...

这里应该有两个 typo：

1. 自动补全candidates，但变成了canidates
2. usage 中的 canidates

exporting bash functions causes jenv to emit spammy error messages

If I export -f a bash function, even something trivial and not having anything to do with jenv, subsequent runs of jenv produce a bunch of errors.

I have this block of code in my .bash_profile:

# dummy function whose existence / exported-ness shouldn't affect anything
foo() {
  echo "bar"
}

# Initialize jenv
eval "$(jenv init -)"

# This works without error.
jenv version

# Necessary if I want to be able to call foo from other scripts
export -f foo

# This now emits a bunch of errors in addition to apparently doing what it's supposed to do.
jenv version

Here is the output when I start a new shell, or source .bash_profile:

Last login: Wed Nov 19 18:12:27 on ttys010

oracle64-1.8.0.05 (set by /Users/ryan/.jenv/version)

The first oracle64-1.8.0.05 line is the first call to jenv version; the second one produces all of that error output (it does produce the correct result though, at the bottom).

Anyone else seen this? I have no clue how/why such a thing could happen.

zsh 支持

试着在 zsh 下安装，发现有比较多的错误，比如：

__jenvtool_init:52: no matches found: JENV_CANDIDATES[@]

zsh 相对 bash 还是有很多优势的，不知可否支持下 zsh

jenv list项目时，第一行总是'-n'. jenv install也总是失败

我昨天才安装的jenv
之前是在zsh中下载，发现不能用，只能转到没有装zsh的root帐号中安装
安装没有问题，按照您给的两行命令安装的

然后在用jenv安装新软件的时候，出现了图中所示的错误

Fix casing in documentation

In Unix environments, case often matters. For example, Java is not installed in .../home, but rather .../Home

Getting dirname error after installing on Mac OS X 10.9

After installing jenv on Mac OS X 10.9 Mavericks, I'm now getting error messages when sourcing ~/.jenv/bin/jenv-init.sh:

matthew@newt:~  
$  . .profile
dirname: illegal option -- b
usage: dirname path
matthew@newt:~ 

If I comment the sourcing of ~/.jenv/bin/jenv-init.sh in ~/.profile, the error message goes away. It doesn't seem to affect the operation of jenv, but it is annoying.

I grepped the shell scripts in ~.jenv/commands but couldn't find where dirname is getting called.

What gives?

Create more flexible candidate versions

For example, if I jenv install gradle 2.7, then jenv should create ~/.jenv/candidates/gradle/2, not just ~/.jenv/candidates/gradle/2.7.

This way, if my jenvrc says:

gradle=2

Then jenv is able to load Gradle 2.x as Gradle "2".

Skip attempting to download 'java' candidates

When jenv fails to find a java candidate installed, it should skip searching the jenv candidate repository, since Java is not available there.

Instead, jenv should display example steps for getting that Java version setup with jenv, like:

JDK <version> not found. Try:

1. Installing Java <version>, such as from Oracle:

http://www.oracle.com/technetwork/java/javase/downloads/index.html

2. Linking java home into jenv candidates, e.g.:

ln -sf <java home> ~/.jenv/candidates/java/<version>

本地repo与远程repo中列出的candidates不一致

在一台ubuntu机器上新安装了jenv，
使用jenv all列出的candidates和jenv.mvnsearch.org上的列表不一致。
是因为这个列表是手动更新，然后忘了同步吗？

软件源更新&gitter

好多软件源都该更新了！！
另建议开通gitter房间便于交流，也便于大家给作者提交不定。

最后要谢谢的你的作品！！

Allow jenv to operate on a specific directory

Currently, it is a hard coded value:

JENV_DIR="$HOME/.jenv"

I think it's more useful to take it possibly from a parameter if present. The use case is that in operational environments, the HOME directory is not usually the place for such purposes. In the end you may call the installation script such as:

curl -L -s get.jenv.io | bash /opt/jenv

问下为啥不加入到brewhome里面去

问下为啥不加入到brewhome里面去，感觉管理起来方便点

Install as default parameter option

Great work jenv team!

As docker gaining momentum on our workflow, is there already a way similar to non-interactively install candidate as default? Such as jenv install --default=no java 1.7 jdk-1.7 instead of creating auto=true on ${JENV}/conf/settings file. Although we can do it using symlink in two step or more. This feature would be Dockerfile friendly.

Thank you.

如何自建软件源？

现在每次都是从mvnsearch.org上来获取资源包，是否可以自定义来源，在内网环境就用不了。

谢谢你提供这么好用的管理工具！

git autocomplete in zsh stop working after install jenv

When using git alias provided by oh-my-zsh, the git autocomplete doesn't work.

Before install jenv:

$ gco <tab>
FETCH_HEAD                    origin/dylib                  origin/remove-prefix-warning  v0.1.2

After install jenv

$ gco <tab>
bin/          libexec/      plugins/      README.md     src/          version                                           
completions/  LICENSE       rbenv.d/      shims/        test/         versions/ 

Related info: ohmyzsh/ohmyzsh#4407

Apparently, removing/commenting setopt completealiases will fix the issue, and won't impart jenv's autocomplete feature.

logstash版本号不对应

expose load command with parameters

I would like to be able to use the load command with a candidate and version as parameters, so I could write my build script like ...

source ~/.profile &>/dev/null
curl -L -s get.jenv.io | bash
source ~/.jenv/bin/jenv-init.sh &>/dev/null
javaVersion=1.8.0_40
mavenVersion=3.0.5
jenv load java $javaVersion
jenv load maven $mavenVersion
export JAVA_HOME=~/.jenv/candidates/java/$javaVersion
export M2_HOME=~/.jenv/candidates/maven/$mavenVersion
$M2_HOME/bin/mvn -version

and I would expect output like

...
Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 14:51:28+0100)
Maven home: /home/cvsuser/.jenv/candidates/maven/3.0.5
Java version: 1.8.0_40, vendor: Oracle Corporation
Java home: /home/cvsuser/.jenv/candidates/java/1.8.0_40/jre
...

An alternate solution would be to not make the install more robust so it would first check for existing installation and not fail.

jenv selfupdate not update repo/central/versions directory

After updating jenv to latest version, I noted that java versions are not refreshed to get 1.8.0_40 and others Java 8 available.

While reading source code, I found the following line: https://github.com/linux-china/jenv/blob/master/src/main/scripts/commands/selfupdate.sh#L59

It will be great if available versions will be updated too.

Thank you!

Too slow

jenv is the slowest part of my bash configuration, often taking longer than a second to load. Please make jenv load faster, like chruby, nvm, and pyenv.

sdk man

发现jenv和sdkman一样一样的。。

Windows version?

Hi,

Any chance of getting this for Windows too? (without Cygwin)?

tnx.

Not supported in cygwin 1.7.5 with win7_x64_en

#1.'jenv default java' cann't find installed jdk

by following your instructions to install java, the last step jenv default java 1.7.0_21 works well in linux, but failed in win7_x64_en with cygwin 1.7.5, here are cygwin's outputs:

daijun@daijun-x64 ~/.jenv/candidates/java 
$ pwd
/home/daijun/.jenv/candidates/java

daijun@daijun-x64 ~/.jenv/candidates/java 
$ ls -l

$ jenv default java 1.7.0_21
Stop! java 1.7.0_21 is not installed.

#2.'jenv install' cann't get any zip from jenv.mvnsearch.org

After skipping the 'install java' step, I try to install maven and other tools. But it alaways return a 404 code. Could you make the download url of cygwin with x64 refer to 32bit's?

ISSUE #26 的回答中提到fixed，但我还是遇到了这个问题。

config auto not work

I set jenv config auto to true,

jenv config auto true

but when I install java or tomcat , it still notice me

Do you want tomcat 7.0.68 to be set as default? (Y/n):

This is aweful when I want to batch install java or others software on many servers.

could you fix this?

Automatically detect and populate java candidates

Offer a command like jenv detect, that automatically finds all installed Java versions, and creates the appropriate candidate links.

For example, if Java 1.8.0_51 and 1.7.0_79 are installed, then jenv detect would create:

• $HOME/.jenv/candidates/java
• $HOME/.jenv/candidates/java/1.8
• $HOME/.jenv/candidates/java/1.8.0
• $HOME/.jenv/candidates/java/1.8.0_51
• $HOME/.jenv/candidates/java/1.7
• $HOME/.jenv/candidates/java/1.7.0
• $HOME/.jenv/candidates/java/1.7.0_51

Stop! XXX is not a valid candidate. When jenv ls

Here is the log. It looks like missing some line for jenv repo update output. And jenv works well in some machine havenot upgrade...

Add zsh support for jenv.

The issue switch java back and forth

I installed java 1.8.0 and 1.7.0_55 on my MAC, and followed the steps to install them in to jenv, but it could accept switching version only once. Then I checked the environment PATH and I found that both path of 1.8.0 and 1.7.0 were set in it . And I noticed that the PATH was set in script jenv_use.sh, I think it is unnecessary because we have $HOME/.jenv/candidates/java/current in PATH environment, we just need re-link current .
