It feels like the concurrent build might be trying to build org.eclipse.jdt.ls.product before its dependencies are done, as it should be built last in a sequential build.

[ppalaga]

If product starts building before some of its undeclared dependencies are built, you can try one the following:

A. Sequential build with mvnd clean verify -DskipTests -1. You can add mvnd.serial = true to your ~/.m2/mvnd.properties to store this pref permanently

B. Make the dependencies explicit using a pom test scope pom, excluding all transitives. There is an example in Camel Quarkus: https://github.com/apache/camel-quarkus/blob/main/catalog/pom.xml#L67-L80
This blog post is related: https://peter.palaga.org/2021/01/12/mvnd-solving-common-issues-of-parallel-builds.html

[gnodet]

The build also fails when running sequentially with mvnd. The problem seems to be the fact that tycho is a maven extension, and has some conflicts with the mvnd works.
The underlying reason is that tycho starts an embedded equinox OSGi runtime (which is a static singleton, so at most one instance per classloader). Given those classes are loaded from the root maven container (because of being an extension), and because mvnd does not dispose the root container (in order to reuse it for speed), the Osgi runtime is never destroyed / recreated. This maintains the whole OSGi services in memory without any way to shut them down at the moment.
The fact that those services are kept in memory is not a problem in itself, but it seems P2 does not support reloading the same repositories. I don't know P2 much, so I haven't yet dig into the details.

[gnodet]

One solution should be to use the new mvnd.pluginRealmEvictPattern pattern to exclude tycho. Unfortunately, only standard plugins are supported, so I'll fix the usage of this property to also evict extension realms. This should work as a workaround.

[gnodet]

The following patch seems to work around the problem: #478

[ppalaga]

Yeah, the workaround is useful. In any case, wouldn't it be worth reporting on Tycho to have a proper fix there?

[gnodet]

@ppalaga I did it yesterday eclipse-tycho/tycho#266
