--------------------------------------
Summary: Groovy incremental compilation failure with traits
Key: GROOVY-10932
URL: https://issues.apache.org/jira/browse/GROOVY-10932
Project: Groovy
Issue Type: Bug
Components: Compiler
Affects Versions: 3.0.15
Reporter: Lóránt Pintér
See reproducer here:
https://github.com/asodja/groovy-traits-compilation-reproducer
This reproduces issue with Groovy traits and Gradle incremental compilation.
Steps to reproduce:
1. git clone [email protected]:asodja/groovy-traits-compilation-reproducer.git
2. run `./gradlew :lib:compileGroovy --no-build-cache`
3. Change `println("a")` in MyTest.groovy to `println("b")`
4. run `./gradlew :lib:compileGroovy --no-build-cache` again
5. See error
To resolve the issue run `./gradlew :lib:compileGroovy --no-build-cache
--rerun-tasks`
Exception thrown:
