Attempting to compile a modular Java project will fail, reporting that it cannot not find the required modules.
I fixed it by adding the module paths manually in
:javac-opts. Could tools.build handle this? Either by adding all the modules to the module path, or ignoring module-info.java and module-info.class.
tools.build/javac will also fail if there is a module-info.class in the classes directory and
tools.build/javac does not find the modules.
