[Solved][1.7.10] ForgeGradle, Groovy, and reobf

[denoflions]

When building a project written in Groovy ForgeGradle seems to have awareness of the fact that it is Groovy since it generates the appropriate tasks to compile it. However, the output doesn't seem to get reobf'd since I get an endless stream of 'No such property' errors any time I hit an obf'd field or method.

 

So unless I've done something wrong configuring my project, I assume getting a mod written in Groovy to load in an obf'd environment is impossible without a go-between java class or metaClass shenanigans. Am I wrong here?

 

edit: I've figured out the solution. You need to set every class that interacts with obf'd minecraft classes to CompileStatic. I wrote a hacky gradle task to accomplish this across the whole project automatically. Slap the following into your build.gradle and away you go.

 

task staticGroovy{

    def base = new File("src/main/groovy")

    base.eachFileRecurse {

        if (!it.isDirectory()){

            if (it.getName().contains(".groovy")){

                def bail = false

                def import_added = false

                def anno_added = false

                def list = [] as List<String>

                def marker = "//Preprocessed."

                def file = it

                list.add(marker)

                it.eachLine {

                    if (it.contains(marker)){

                        bail = true

                    }

                    def name = FilenameUtils.removeExtension(file.getName())

                    if (it.contains("class ${name}") && it.contains("{") && !anno_added){

                        list.add("@CompileStatic")

                        anno_added = true

                    }

                    list.add(it)

                    if (it.contains("package ") && !import_added){

                        list.add("")

                        list.add("import groovy.transform.CompileStatic")

                        import_added = true

                    }

                }

                if (!bail){

                    BufferedWriter out = new BufferedWriter(new FileWriter(it))

                    list.each{

                        out.write(it)

                        out.newLine()

                    }

                    out.flush()

                    out.close()

                }

            }

        }

    }

}
