val Project.`DEVELOP`: Any get() =
    extensions.getByName("DEVELOP")

The culprit is the link to the extension type in the kdoc comment.
[DEVELOP][com.github.blindpirate.gogradle.core.mode.BuildMode.]
Note the . (dot) at the end of the type name.

[mkobit]

com.github.blindpirate.gogradle.core.mode.BuildMode is the type and both of those extensions are enum values.

public enum BuildMode {
    DEVELOP("DEV") {
        @Override
        public GolangDependencySet determine(GolangDependencySet declaredDependencies,
                                             GolangDependencySet lockedDependencies) {
            return declaredDependencies;
        }
    },
    REPRODUCIBLE("REP") {
        @Override
        public GolangDependencySet determine(GolangDependencySet declaredDependencies,
                                             GolangDependencySet lockedDependencies) {
            return lockedDependencies;
        }
    };
   // ...

Same thing with the other TimeUnit extensions added by the plugin.

I'm also wondering if value extensions like a String are also affected.

[mkobit]

The plugin adds them at https://github.com/gogradle/gogradle/blob/8d5852a3642cbf4d914ba2568209853ee9c6dc59/src/main/java/com/github/blindpirate/gogradle/GolangPlugin.java#L65-L73 which doesn't provide a public type for each when using project.getExtensions().add(mode.toString(), mode);

This looks like it could possibly be an issue in how upstream gradle/gradle handles these

[mkobit]

Trying these two tests in org.gradle.model.internal.core.ModelTypeTest

    enum MyEnum {
        ONE,
        TWO
    }

    def "represents enums"() {
        given:
        def enumType = MyEnum.class
        def enumInstanceType = MyEnum.ONE.class

        expect:
        def modelOfEnum = ModelType.of(enumType)
        def modelOfInstance = ModelType.of(enumInstanceType)
        modelOfEnum == modelOfInstance
    }

    def "represents enums that contain definitions"() {
        given:
        def enumType = TimeUnit.class
        def enumInstanceType = TimeUnit.SECONDS.class

        expect:
        def modelOfEnum = ModelType.of(enumType)
        def modelOfInstance = ModelType.of(enumInstanceType)
        modelOfEnum == modelOfInstance
        modelOfInstance.displayName == 'TimeUnit'
        modelOfEnum.toString() == 'java.util.concurrent.TimeUnit'
    }

The first one using MyEnum succeeds but the TimeUnit one does not because (I'm guessing) some difference in how the internal wrapper arounds the types handle it here. I was planning on working on a fix for this but I don't have any more time today!

Thanks for the investigation Mike!

[eskatos]

Thanks to your investigation @mkobit I was able to quickly open https://github.com/gradle/gradle/pull/4686 that should fix this issue.

[eskatos]

Some more gymnastic is needed to fix this, reopening

[eskatos]

https://github.com/gradle/gradle/pull/4688 reverted upstream, new attempt in https://github.com/gradle/gradle/pull/4726

[eskatos]

Take 2 merged upstream https://github.com/gradle/gradle/pull/4726

[eskatos]

Confirmed fixed by gradle/gradle#4726

This repository wrapper now has the fix.
This snapshot distro includes the fix: https://repo.gradle.org/gradle/dist-snapshots/gradle-kotlin-dsl-4.7-20180315091131+0000-bin.zip
It'll be delivered as part of gradle-kotlin-dsl-0.16.x + gradle-4.7-rc-1
