When tipping in console “./gradlew genSources”, I get an error “Could not find or load main class worker.org.gradle.process.internal.worker.GradleWorkerMain”:
Task :genSourcesWithVineflower
Decompile cache stats: 0 hits, 4480 misses

Now please the contents of C:\Users\╨Ъ╨╕╤А╨╕╨╗╨╗7\.gradle\.tmp\gradle-worker-classpath11484559399845350744txt.
My suspicion is that maybe some part somwhere has problems with the characters in your user name.
So besides showing that file’s contents, you could try to run with a different GRADLE_USER_HOME directory. If that solves it, you should probably still report this as bug.
