Support Module System in Java 9+ #941

Open rahulmutt opened 5 years ago

rahulmutt commented 5 years ago

Java 9+ introduced the module system by specifying module-info.java or module-info.class.

Implementing this requires:

Adding support for Module and Package constants in codec-jvm
Adding support for Module attribute in codec-jvm
Generating module-info.class inside of the compiler and packaging it in the final jar file.
Generating jmod files instead of jar files if the target is >= 9 for every Eta module.

The trickiest problem to resolve here is that the module system does not support cyclic dependencies while Eta supports source imports so we need to find a way to encode that somehow.
