For the record, here is the full commandline passed to jdt and the error message: > [**INFO**] Compiling 1 source file to /home/runner/work/tycho/tycho/tycho-its/target/projects/MavenCompilerPluginTest/testMavenCompilerPluginModuleWithTests/compiler.mavenCompilerPlugin.moduleWithTests/target/test-classes > [**DEBUG**] JDT compiler args: [--patch-module, ex=/home/runner/work/tycho/tycho/tycho-its/target/projects/MavenCompilerPluginTest/testMavenCompilerPluginModuleWithTests/compiler.mavenCompilerPlugin.moduleWithTests/target/classes:/home/runner/work/tycho/tycho/tycho-its/target/projects/MavenCompilerPluginTest/testMavenCompilerPluginModuleWithTests/compiler.mavenCompilerPlugin.moduleWithTests/src/test/java:/home/runner/work/tycho/tycho/tycho-its/target/projects/MavenCompilerPluginTest/testMavenCompilerPluginModuleWithTests/compiler.mavenCompilerPlugin.moduleWithTests/target/generated-test-sources/test-annotations:,...

@iloveeclipse can you tell if tycho is doing anything wrong here or if this is a user error?

The code is here: https://github.com/eclipse-tycho/tycho/tree/8d696d614a95000438b379bdeb41f2e0d9f322e7/tycho-its/projects/compiler.mavenCompilerPlugin.moduleWithTests The JDT compiler arguments generated by Tycho is here: https://github.com/eclipse-tycho/tycho/pull/809#issuecomment-1101136523 Original compiler output: Unrecognized option : --patch-module If I understand @jason-faust correctly `javac` can compile...

I'm not sure if one can transform this into an eclipse project, this uses maven to replace the `javac` compiler by using `ejc` (see here https://github.com/eclipse-tycho/tycho/blob/8d696d614a95000438b379bdeb41f2e0d9f322e7/tycho-its/projects/compiler.mavenCompilerPlugin.moduleWithTests/pom.xml) so not a "traditional"...

By the way javac says: ``` javac --patch-module ex=/tmp/tycho-bug/tycho-its/projects/compiler.mavenCompilerPlugin.moduleWithTests/target/classes:/tmp/tycho-bug/tycho-its/projects/compiler.mavenCompilerPlugin.moduleWithTests/src/test/java:/tmp/tycho-bug/tycho-its/projects/compiler.mavenCompilerPlugin.moduleWithTests/target/generated-test-sources/test-annotations: --add-reads ex=ALL-UNNAMED -s /tmp/tycho-bug/tycho-its/projects/compiler.mavenCompilerPlugin.moduleWithTests/target/generated-test-sources/test-annotations -d /tmp/tycho-bug/tycho-its/projects/compiler.mavenCompilerPlugin.moduleWithTests/target/test-classes -classpath /tmp/tycho-bug/tycho-its/projects/compiler.mavenCompilerPlugin.moduleWithTests/target/test-classes /tmp/tycho-bug/tycho-its/projects/compiler.mavenCompilerPlugin.moduleWithTests/src/test/java/ex/ATest.java -g -nowarn -target 11 -source 11 --release 11 error: option --source cannot...

@iloveeclipse is the provided example suitable? Is this a bug I should report to JDT?

@jason-faust can you please resolve the conflict and rebase on current master?
