[tycho-user] P2 repository ignored with Java 11?

[Axel Guckelsberger <info@xxxxxxxx>]

Hi all,

I am currently migrating a project from Java 8 to Java 11. The Jenkins 
jobs work based on that in addition to the common target definition 
there are additional p2 repositories consumed for materialising the 
target platform. So while the parent POM contributes the target platform 
the component's POM adds one or several repository entries like this:

    <repositories>
        <repository>
            <id>some-dependency</id>
            <url>file://${dependency.repository}</url>
            <layout>p2</layout>
        </repository>
    </repositories>

The idea behind that is that all jobs share the target platform, but 
still can depend on each other. For example component C needs components 
A + B and so on.

When using Java 8 the output before "[INFO] Resolving dependencies of 
MavenProject:" was:

> Adding repository 
> file:/...jenkins/jobs/.../branches/master/lastSuccessful/...dependency-component.build/target/repository

Now with Java 11 this step is unfortunately skipped which leads to that 
the dependency can not be resolved.

Any idea what could cause this different behaviour and/or how a 
workaround could look like?

I am using Tycho 1.4.0.

TIA
Axel
