tycho-p2-extras-plugin:publish-features-and-bundles - Unresolved requirement: Import-Package: org.eclipse.tycho

[laeubi]

1. goto tycho-extras/tycho-p2-extras-plugin/target/test-classes/publisher/testProject
2. run mvn clean install -X -Dtycho-version=2.4.0-SNAPSHOT

This results in printing

!ENTRY org.eclipse.tycho.p2.resolver.impl 4 0 2021-05-04 11:16:10.614

to the debug console output (and some more)

org.eclipse.tycho is supposed to come from the bootclasspath so it seems the tycho-p2-extras-plugin is missing some depdencies.

Any hint what one has to look for? This happens wehn using the 'P2ApplicationLauncher'...

[laeubi]

This is caused because P2ApplicationLauncher forks a new process (an thus the boot classpath is not available), so we need distinguish between the two case.

Another issue when running in -X mode the "-console" parameter is added leading to

org.osgi.framework.BundleException: Could not find bundle: org.eclipse.equinox.console

We can support this by adding the console bundles to the tycho-external product
