Re: [cross-project-issues-dev] Gotchas Building Against Eclipse 4.20

Hi

You may also find https://bugs.eclipse.org/bugs/show_bug.cgi?id=569379 relevant if you move on from an old Tycho to avoid IPlatformRunnable.

It would appear that something in the auto-POM logic ignores the MANIFEST.MF BREE and instead picks one from an explicit pom.xml BREE so avoid vintage BREEs in test plugins.

Inconsistent org.eclipse.jdt.core.prefs between plugins can also be a problem. Maybe OOMPH can avoid this.

If you  use JDT's @NonNull annotations it is essential that you set deriveReleaseCompilerArgumentFromTargetLevel false.

BREE 1.6  and when I moved them to BREE 1.8, that magically avoided the
Tycho compile errors.  Probably others won't have such a problem, but
maybe good to keep in mind.
