btw problems with scalap mean problems with incompatibility of java bytecode. so maybe it is good enough to clean build project assuring first that it is working with java 8 not 9 or 7? 2017-10-14 19:35 GMT+02:00 Wieslaw Popielarski <wpopielarski@gmail.com>:

I've noticed that this happens when I have Scala IDE installed and I'm switching workspace from the one containing Play project to the one containing SpringBoot project

wpopielarski · 2017-10-20T06:51:58Z

ok, but are these projects using same java version to compile? 2017-10-19 12:40 GMT+02:00 Kamil <notifications@github.com>:
