Neeraj Jain :
I recently upgraded my project from Oracle JDK8 to OpenJDK 11.0.2
Java Version in my system
openjdk 11.0.2 2019-01-15
OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)
When I build my project using maven from the terminal it compiles fine but is failing while building the same using IntelliJ. There is no stack trace to look upon, every time I build the project it shows me this error.
This says it's a NullPointerException and I know we have lots of duplicate questions on SO for the same, I am not asking to resolve NullPointer but instead if someone can help me just figure out a way to check the logs while building the project using play button in IntelliJ, I will help myself afterward.
I checked the idea.log file and there is nothing to be suspicious about.

y.bedrov :
Disabling "Atlassian Clover for IDEA" plugin helped in this case.
