Oh .. that would be hard to debug without further analysis. Essentially Java is not seeing libraries in the classpath. The classpath is defined _inside_ the jar file with pointers to where the gradle cache is located.
So it could be many things, maybe you did not make a first run with gradle to download the cache, or maybe you have different users inside the container each with their own cache directory. Another possibility is that you mounted a volume on top of the downloaded cache.
