tycho-example's Introduction

Maven / Tycho build example

Demonstrates the usage of the Maven Tycho build system for Eclipse plug-ins, Eclipse RCP and OSGi based applications.

The following is demonstrated:

Pomless build for bundles, tests and features
P2 update sites
Product builds
Generate sources
Generate JavaDoc
Target definition build

tycho-example's Issues

Make the Java 11 requirement "official"?

first: Thanks for this working example! One thing: The example does not work with Java 8, main log lines:

!ENTRY org.eclipse.equinox.simpleconfigurator 4 0 2021-11-22 09:44:17.944
!MESSAGE FrameworkEvent ERROR
!STACK 0
org.osgi.framework.BundleException: Could not resolve module: org.eclipse.equinox.simpleconfigurator [2]
  Unresolved requirement: Require-Capability: osgi.ee; filter:="(&(osgi.ee=JavaSE)(version=11))

So, would it be beneficial to raise the required execution environment in com.vogella.tycho.rcp to Java 11 as well?

Build on console doesn't work

I cloned the repo and started the build at the command line with
mvn clean verify

This is the error log.

Why isn't it possible for Maven to resolve org.eclipse.swt.SWT. In eclipse the product runs without any problem.

jenkins maven greater than 3.3.9 and code in subdirectory

Hello, thanks for the nice example. We tried to build it on our Jenkins Server. We have found two problems when building the project.
It does not build when source is checked out to a subdirectory and -f subdirectory/pom.xml is used. Maven Versions greater than 3.3.9 fail.

Removing product pom fails the build

If I remove the product pom file the build fails. I though pomless build support that now. Any advice @laeubi?

Javadoc configuration is missing for pomless

I can not find the Javadoc configuration is for pomless. Before pomless there is a help plugin which is later removed. Would be nice to have an example.

Error with maven wrapped

Hello,
I'm a french developer, my name is Nathan and I try to test your project to reproduce your configuration for a project,
but when I tried to run commands with your wrapped maven I got this error:

"'#' is not recognized as an internal order or external, an executable program or a command file."

On Powershell and on my WSL configuration with Ubuntu, do you know why?

Windows 10 (Powershell V5.1.19041.3693) :

WSL2, Ubuntu :

2018-12 update site breaks the build

To get to this point i needed to add Required Features to com.vogella.tycho.feature

pom.xml missing for bundles

I just downloaded the example project and it looks like the pom.xml is missing for the bundles.

mvn clean validate not working behind company proxy

Hi,

Running on Maven 3.5.2

I'm getting the exception below when running
mvn clean validate
on the root project. With Debug logging enabled, I can see the logs showing the maven plugin is picking up the proxy I have defined in my settings.xml but doesn't seem to be using it to access the P2 site.

[DEBUG] Clearing proxy settings in OSGi runtime
[DEBUG] Configuring proxy for protocol https: host=mycompanyproxyhost, port=8080, nonProxyHosts=

Since it was warning about the system property not being set, I also tried the following command:

mvn clean validate -Dhttps.proxyHost=mycompanyproxy -Dhttps.proxyPort=8080

but still get the same 'connection timed out' error. I've tried accessing the download site directly and it loads for me: http://download.eclipse.org/eclipse/updates/4.6/

I'm not sure if the error is related to it looking for http://download.eclipse.org/eclipse/updates/4.6/content.xml as that path doesn't exist but it may be a red herring
