Subject [jira] [Created] (GROOVY-8385) CompileStatic: Improved method call/property access Java compatibility for Minecraft Forge obfuscation support
Date Sat, 18 Nov 2017 17:42:00 GMT
mgroovy created GROOVY-8385:
-------------------------------

             Summary: CompileStatic: Improved method call/property access Java compatibility
for Minecraft Forge obfuscation support
                 Key: GROOVY-8385
                 URL: https://issues.apache.org/jira/browse/GROOVY-8385
             Project: Groovy
          Issue Type: Improvement
          Components: bytecode
            Reporter: mgroovy
            Priority: Minor


* Even with @CompileStatic the Groovy compiler creates bytecode for method calls / property
access which is dynamic in nature. 
* This means that e.g. Minecraft Forge's obfuscator does not pick up the calls in the generated
bytecode, which means they do not get obfuscated, which in turn makes the code fail when executed
in Minecraft.
* This effectively makes it nearly impossible to write Minecraft mods with Groovy, which in
turn is a wasted opportunity to get people involved with Groovy early on.
* Possible approaches to improve the situation:
## Improve on a fundamental level: According to [~paulk] only a few calls are required to
be done dynamically for Groovy functionality to work as expected under @CompileStatic. 
*** The problem seems to be that it could be hard to be a 100% sure no edge case is overlooked,
as to not break @CompileStatic in situations where e.g. no 100% Java-call-compatibility is
needed.
## Improve through newly introduced @CompileStatic parameters
*** => Static method call / property access bytecode is generated for method code / all
class methods repectively (with possible exceptions for the know cases mentioned above).
## Improve through newly introduced @ObfuscationJavaCompatibility annotation that can be put
on a method or class
*** behavior same as for @CompileStatic parameters above
