Having JMH benchmarks while compiling with Ajc compiler breaks the build with an error #14

Closed gvlasov closed 4 years ago

gvlasov commented 9 years ago

When I'm using JMH plugin with Compiler → Java Compiler → Use compiler set to Ajc (AspectJ compiler), and there are JMH benchmarks in my project, I'm getting the following error when compiling any class. I can prevent the error doing a clean build (by removing the target directory or doing Rebuild project), but doing incremental builds results in this:

Error:ajc: Error writing benchmark list javax.annotation.processing.FilerException: createResource. Resource already created : CLASS_OUTPUT//META-INF/BenchmarkList --- uri = file:/home/suseika/IdeaProjects/eloquent-aspects/target/test-classes/META-INF/BenchmarkList

Why would you need to compile with AspectJ? To test aspect advice? Aspects are implemented as a bytecode manipulation and JMH also performs some transformations. Probably JMH should itself support ajc but I guess this will never happen. Currently only HotSpot JVM and compiler supported. I'll close the ticket because I don't see anything that we as developers of JMH plugin can make here. Feel free to reopen ticket if you know what exactly we should do here
