Uninstalling java JDK, Reinstall I tried setting up java home and bin.

Answer 1

I had came across the same situation, after runnig.bat file that launches Nifi, it simply did not start and the cmd returned to its initial state.

This solution helped. Try to clear all folders with '*_repository' name.
