Hello @walles, Thank you for submitting issues I did not updated plugin for a long time... I'll try to fix some problems like this one and #27 and release new version

There is also a stand-alone version that does not require an IDE, but I need to write a proper instruction and upload built jar, so people don't have to build it from sources
