Please do not split topics across several threads. This makes following the conversation in the threads view very hard as the context of the other messages is missing. If you have additional information either edit the original message or post to its thread. Regarding the problem, it's impossible to tell what's wrong from what your showed. The only thing that is clear is, that you do not have a Gradle problem, so asking here is wrong. You start a Java process and that exits with non-0 exit code which usually means error. Almost all programs also output that error, just scroll up or debug your program. You could actually ignore the non-0 exit code using Gradle, but it is extremely unlikely that this is what you need.
