I tried to follow this description: https://www.openhab.org/docs/developer/development/ide.html
Unfortunately it is not possible to perform the setup tasks. Here is my stacktrace:
Performing Preference /instance/org.eclipse.jdt.ui/formatter_profile = _ESH
Performing JRE for JavaSE-1.8 = C:\Program Files\Java\jre-9.0.4
Creating JRE for JavaSE-1.8 with location C:\Program Files\Java\jre-9.0.4
ERROR: org.eclipse.jdt.launching code=0 Target is not a JDK Root. Java executable was not found
I guess that it was working on my other environment with an older version of the Eclipse Installer. Summing up, how should I proceed now? Thanks in advance for sending me an old version of the Eclipse Installer or for giving me some hints how to solve this issue?
