Javac option `-parameters` has no effect on javaCompile task on Gradle2.6/JDK8u60

It seems that Gradle javaCompile task doesn’t take compile option -parameters into count.

Here is related post by me.

It seems that javac compiler options is not passed to compileJava task on Gradle2.6 with JDK8u60

Hi. I’m checking JDK8u60’s bug fix of JDK-8079044 javac -parameters does not emit parameter names for lambda expressions with a project, which requires javac option -parameters to work correctly, as subprojects. But It seems that Gradle’s compiler setting compileJava.options.compilerArgs is not passed to the subproject’s compileJava task. The project structure is as follows. rootProject +-setting.gradle +-build.gradle +-src | +-main | | +-groovy | | +-my.pkg | +-test | +-groovy | +-my…

JDK8u60 fixed bug of javac option -parameters, and JDK8u60’s javac can produce byte code which can retrieve lambda parameter’s name by reflection. But classes compiled by Gradle, cannot retrieve lambda parameter.

I think it is a bug on Gradle compileJava task.

Hi @Shinya_Mochida, I replied to your other topic. This isn’t a bug. Both the main and test sources need to be compiled with -parameters for your example to work.

I’m going to close this topic, please let me know if you have any questions on the old topic.
