A modern programming language that makes developers happier.

kotlinlang

Another weird thing I can not reproduce: it worked once to compile from cmd line, I cleaned before, ran "mvn compile" got success, cleaned again, ran compile and it failed. The code itself wasn't changed. Kinda clueless right now

Just in case anyone wonders: I had hibernate that was scanning for metamodel before all the compilation, hence it caught the errors. Making phase of kotlin compilaton before hibernate solved my problem of compiling. (Have not tested other effects of this)
