Gili commented on MCOMPILER-369: -------------------------------- Now that nabble is dead, the above discussion can be found at https://mail.openjdk.org/pipermail/jigsaw-dev/2016-November/010201.html > Adding module-info.java breaks JMH annotation processor > ------------------------------------------------------- > > Key: MCOMPILER-369 > URL: https://issues.apache.org/jira/browse/MCOMPILER-369 > Project: Maven Compiler Plugin > Issue Type: Bug > Affects Versions: 3.8.0 > Reporter: Gili > Priority: Major > Attachments: annotation-processor-jigsaw.zip > > > # Open testcase > # Run {{clean install}}. Notice that the benchmarks run. > # Open {{pom.xml}} and comment-out the {{<annotationProcessorPaths> > section.}} > # Run {{clean install}}. Notice that the annotation processor does not run > and the benchmarks break. > # Delete/rename {{module-info.java}}. > # Run {{clean install}}. Notice that the benchmarks work again. > The documentation for {{<annotationProcessorPaths>}} states that by default > annotation processors are detected from the classpath. It seems that adding > {{module-info.java}} breaks that somehow, which is weird/unexpected because > JMH exists as a dependency outside the newly-declared module. > I did two things to prove that the annotation processor is not being invoked > in step 4: > # Notice that {{target/test-classes/META-INF}} is not created. > # Place a breakpoint in {{org.openjdk.jmh.generators.BenchmarkProcessor}} > and notice that it is never even constructed. > I tried digging into the maven-compiler-plugin and plexus-compiler > source-code but couldn't figure out where the problem is. The only workaround > I found is to specify {{annotationProcessorPaths}} manually but it took me > half a day to track down this problem. > Any idea what is going on?
