Description

The attached app contains the following code:

src/demo/SomeTrait.groovy

package demo

trait SomeTrait {
    private static String someString
}

src/demo/SomeClass.groovy

package demo

class SomeClass implements SomeTrait {}

test/demo/SomeTestClass.groovy

package demo

class SomeTestClass implements SomeTrait {}

SomeClass.groovy will compile. SomeTestClass.groovy will not compile.

$ ./gradlew clean cTG
:clean
:compileJava UP-TO-DATE
:compileGroovy
:processResources UP-TO-DATE
:classes
:compileTestJava UP-TO-DATE
:compileTestGroovy
