Error:BUG! exception in phase 'class generation' in source unit '_BuildScript_' unsupported Target MODULE

Question

I\'m trying to create a new Java 9 project using gradle but right after project creation I received error from gradle:

Error:BU         


        

Answer 1

I have solved it by downgrading Gradle JVM to 8. It is not perfect but keeps you going while jdk9 and gradle and intellij stabilises.

Intellij View

Answer 2

Seems fixed in 2017.3

See IntelliJ IDEA 2017.3 173.2941.3 Release Notes: https://confluence.jetbrains.com/display/IDEADEV/IntelliJ+IDEA+2017.3+173.2941.3+Release+Notes

See issue: https://youtrack.jetbrains.com/issue/IDEA-171520

Answer 3

Setting the Gradle home to local Gradle distribution solved the issue in my case.

• Java version: 9+181
• Gradle version: 4.1
• Intellij version: 2017.2.2

if we set to use default Gradle wrapper, IntelliJ downloads an earlier version of Gradle. I think it is the reason for failure.
