Hi, For 4.19.0.AM1 to be released by the end of March, we introduce a major change in the parent POM that could lead to some unexpected breaks. This change is the move to a new Tycho version, from 1.7 to 2.2. This issue is tracked in the public JIRA here: https://issues.redhat.com/browse/JBIDE-27614 Tycho 2 is compatible with java15 and parallel builds but also introduces changes at the way the target platform is resolved and this can lead to build errors. As a direct implication, the targetjre used in the targetplatform moved to JavaSE-11 and the maven version to use must be at least maven 3.6.3. ( as indicated here: https://wiki.eclipse.org/Tycho/Release_Notes/2.0#Update_requirements) As we look closely at the different jobs/builds, jbosstools builds can be very unstable for some time. NOTE: parent pom PR is not merged yet: https://github.com/jbosstools/jbosstools-build/pull/312 Regards, -- Stéphane Bouchet Senior Software Engineer, R&D Red Hat <https://www.redhat.com/> <https://www.redhat.com/>
