Re: [tycho-user] Testing staged Tycho 2.0.0

Maybe its just me, but I have never succeed in "or updates are forced" (it would be incredible helpful if maven would actually tell HOW this could be forced in the error message), so I ended up wit going to my local m2 repository and removing the org/eclipse/tycho folder to force retry of download.

Also keep in mind that if using pomless-build you need to configure the repository inside the settings.xml to be picked up.

Not importing javax.annotation was and is always an error in OSGi, so you could save you some headaches to explicitly add these import even though in eclipse (and tycho) is has worked the past years without it.

I wanted to test the staged Tycho 2.0.0 today for some projects. But I have problems getting even the first build to finish. Not sure if it is an issue in the setup to consume the staged Tycho plugins.

I added the following lines to the pom.xml of the project I want to test (also tried adding it to the settings.xml)



<url></url <>>


When I execute the build I get the following error:

Plugin org.eclipse.tycho:tycho-p2-director-plugin:2.0.0-SNAPSHOT or one of its dependencies could not be resolved: Failure to find org.eclipse.tycho:tycho-p2-director-plugin:jar:2.0.0-SNAPSHOT in was cached in the local repository, resolution will not be reattempted until the update interval of tycho-staged has elapsed or updates are forced

Even running the build using *mvn –U clean verify* the error occurs. Am I missing something?

In the build log I see the following warning multiple times:

[WARNING] The POM for org.eclipse.tycho:tycho-p2-director-plugin:jar:2.0.0-SNAPSHOT is missing, no dependency information available

Could it be related to this somehow?

Additionally I have another error. Since Tycho 2.0.0 requires minimum Java 11 I updated my build environment to use a Java 11 JDK for the build. I left the project unchanged that builds with Java 8 and Tycho 1.7 fine. The build fails with the following error:

!ENTRY org.eclipse.tycho.surefire.junit4 2 0 2020-08-12 10:43:41.356

!MESSAGE Could not resolve module: org.eclipse.tycho.surefire.junit4 [20]

   Unresolved requirement: Import-Package: javax.annotation

After searching a bit I have found out that this should have been fixed with Tycho 1.4 <>

Following the suggestions in this ticket I added javax.annotation from Orbit to the target platform. But this still does not fix the issue. I have to add javax.annotation to the test bundle so it gets added to the test runtime. But I understood from the comments in the bug report that this should not be necessary if javax.annotation is included in the target platform. I am using a target definition based build.

Is there anything else that has to be configured to make Tycho based builds that contain test bundles to run with Java 11?

BTW, this also happens with older Tycho versions. So probably not related to 2.0.0.


I am using the pom-less Tycho approach and all projects still have the BREE 1.8 set.
