Java Version Manager inspired by nvm (Node.js). Written in Go.
The goal is to provide unified pain-free experience of installing (and switching between different versions of) JDK regardless of the OS (macOS, Linux x86/x86_64/ARMv7+, Windows x86_64).
jabba install
- Oracle JDK (latest-version only)
- Oracle Server JRE (latest-version only),
- Adopt OpenJDK (jabba >=0.8.0 is required)
- Hotspot
- Eclipse OpenJ9
- Zulu OpenJDK (jabba >=0.3.0 is required)
- IBM SDK, Java Technology Edition (jabba >=0.6.0 is required)
- GraalVM CE
- OpenJDK
- OpenJDK Reference Implementation
- OpenJDK with Shenandoah GC (jabba >=0.10.0 is required)
- Liberica JDK
- Amazon Corretto
... and from custom URLs.
(in bash/zsh/...)
export JABBA_VERSION=...
curl -sL https://github.com/shyiko/jabba/raw/master/install.sh | bash && . ~/.jabba/jabba.sh(use the same command to upgrade)
The script modifies common shell rc files by default. To skip these provide the --skip-rc flag to install.sh like so:
export JABBA_VERSION=...
curl -sL https://github.com/shyiko/jabba/raw/master/install.sh | bash -s -- --skip-rc && . ~/.jabba/jabba.shMake sure to source jabba.sh in your environment if you skip it:
export JABBA_VERSION=...
[ -s "$JABBA_HOME/jabba.sh" ] && source "$JABBA_HOME/jabba.sh"In fish command looks a little bit different - export JABBA_VERSION=...
curl -sL https://github.com/shyiko/jabba/raw/master/install.sh | bash; and . ~/.jabba/jabba.fish
If you don't have
curlinstalled - replacecurl -sLwithwget -qO-.
If you are behind a proxy see - curl / wget manpage. Usually simple
http_proxy=http://proxy-server:port https_proxy=http://proxy-server:port curl -sL ...is enough.
NOTE: The brew package is currently broken. We are working on a fix.
While you can use the same snippet as above, chances are you don't want jabba binary & shell
integration script(s) to be included in the final Docker image, all you want is a JDK. Here is the Dockerfile showing how this can be done:
FROM buildpack-deps:jessie-curl
RUN curl -sL https://github.com/shyiko/jabba/raw/master/install.sh | \
JABBA_COMMAND="install 1.15.0 -o /jdk" bash
ENV JAVA_HOME /jdk
ENV PATH $JAVA_HOME/bin:$PATH(when
JABBA_COMMANDenv variable is setinstall.shdownloadsjabbabinary, executes specified command and then deletes the binary)
$ docker build -t <image_name>:<image_tag> .
$ docker run -it --rm <image_name>:<image_tag> java -version
java version "1.15.0....(in powershell)

# list available JDK's

# uninstall JDK

# link system JDK

jabba use [email protected]
jabba use zulu@~1.6.97
echo "1.8" > .jabbarc
# switch to the JDK specified in .jabbarc (since 0.5.0)
jabba use
# set default java version on shell (since 0.2.0)
# this version will automatically be "jabba use"d every time you open up a new terminal
jabba alias default 1.8
.jabbarchas to be a valid YAML file. JDK version can be specified asjdk: 1.8or simply as1.8(same as~1.8,1.8.x">=1.8.0 <1.9.0"(mind the quotes)).
jsyk: jabba keeps everything under
~/.jabba(on Linux/Mac OS X) /%USERPROFILE%/.jabba(on Windows). If at any point of time you decide to uninstall jabba - just remove this directory.
For more information see jabba --help.
PREREQUISITE: go1.8

cd $GOPATH/src/github.com/shyiko/jabba
make fetch
go run jabba.go
# to test a change
make test # or "test-coverage" if you want to get a coverage breakdown
# to make a build
make build # or "build-release" (latter is cross-compiling jabba to different OSs/ARCHs) Q: What if I already have java installed?
A: It's fine. You can switch between system JDK and jabba-provided one whenever you feel like it (jabba use ... / jabba deactivate).
They are not gonna conflict with each other.
Q: How do I switch java globally?
A: jabba doesn't have this functionality built-in because the exact way varies greatly between the operation systems and usually involves elevated permissions. But. Here are the snippets that should work:
- Windows
(in powershell as administrator)
# select jdk
jabba use ...
# modify global PATH & JAVA_HOME
$envRegKey = [Microsoft.Win32.Registry]::LocalMachine.OpenSubKey('SYSTEM\CurrentControlSet\Control\Session Manager\Environment', $true)
$envPath=$envRegKey.GetValue('Path', $null, "DoNotExpandEnvironmentNames").replace('%JAVA_HOME%\bin;', '')
[Environment]::SetEnvironmentVariable('JAVA_HOME', "$(jabba which $(jabba current))", 'Machine')
[Environment]::SetEnvironmentVariable('PATH', "%JAVA_HOME%\bin;$envPath", 'Machine')
- Linux
(tested on Debian/Ubuntu)
# select jdk
jabba use ...
sudo update-alternatives --install /usr/bin/java java ${JAVA_HOME%*/}/bin/java 20000
sudo update-alternatives --install /usr/bin/javac javac ${JAVA_HOME%*/}/bin/javac 20000
To switch between multiple GLOBAL alternatives use
sudo update-alternatives --config java.
