java.lang.NoClassDefFoundError in Maven build after installing eclipse WindowsBuilder plugin

Time:10-21

I am working with eclipse Version: 2022-03 (4.23.0) Build id: 20220310-1457 and Maven. If I build without Maven - it works.

My Maven build also worked fine until a new plugin "Windows Builder" was installed. Since then I am getting the following error message:

constituent[40]: file:/C:/eclipse/configuration/org.eclipse.osgi/1285/0/.cp/
constituent[41]: file:/C:/eclipse/configuration/org.eclipse.osgi/443/0/.cp/
constituent[42]: file:/C:/eclipse/configuration/org.eclipse.osgi/20/0/.cp/
---------------------------------------------------
Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/util/concurrent/internal/InternalFutureFailureAccess
    at java.base/java.lang.ClassLoader.defineClass1(Native Method)

I included the first 3 lines, because when I compare the old configurations, there are a lot of new folders in the configuration/org.eclipse.osgi - these three folders are definitely not in the old configuration and that seems to be causing the problem. If I delete these folders eclipse doesn't work any more.

Just in case it is necessary this is my pom.xml:

I finally found the source of the problem. The Admin installed the Nightly Build of WindowBuilder. If instead just the version 1.9.8 is installed everything works again. enter image description here
