Answer 1

By Changing The SDK version, I have fixed my issue... and some other have suggested the same thing.

My jdk1.8.0_20 was not working. So i have just changed the jdk to jdk-12.0.2. I don't know if it is correct or not.

This question is related to some other question but i could not find it then...

1. Scala build crashed

Problem was in minor JDK version. Scala 2.12 require's newer version of JDK then 1.8.0_111. So after JDK upgrade everything work.

i wish it might help some.

Thanks.
