[Kengo TODA (Jira)]

Kengo TODA created GROOVY-10162:
-----------------------------------

             Summary: GroovyDoc generates CLASS_NAME.1.html if an enum class 
has an abstract method
                 Key: GROOVY-10162
                 URL: https://issues.apache.org/jira/browse/GROOVY-10162
             Project: Groovy
          Issue Type: Bug
          Components: GroovyDoc
    Affects Versions: 3.0.8
         Environment: Ubuntu 20.04.2, Adoptopenjdk 11.0.11+9 x64
            Reporter: Kengo TODA
         Attachments: groovydoc build by Groovy 3.0.8.zip

I found that the GroovyDoc generates `CLASS_NAME.1.html` if an enum class has 
an abstract method. I found this in the [spotbugs-gradle-plugin 
project|https://github.com/spotbugs/spotbugs-gradle-plugin/blob/3351d2b8626fa33ca6469126db1d0c220ffac9a6/src/main/groovy/com/github/spotbugs/snom/Confidence.groovy],
 and I've created a [MCVE project at 
GitHub|https://github.com/KengoTODA/unexpected-groovydoc-reproduction/tree/8b24a69f3950473bdc9f08ff930a7fccb17eefea].
 The code to reproduce will be like below:

{code:groovy}
enum TestWithAbstractMethod {
    FOO {
        int method() { return 0; }
    },
    BAR {
        int method() { return 1; }
    }
    abstract int method();
}
{code}

You can find generated HTML files in [this GitHub Actions Workflow 
Run|https://github.com/KengoTODA/unexpected-groovydoc-reproduction/actions/runs/1013816748].
 It includes not TestWithAbstractMethod.html but 
TestWithAbstractMethod*.1*.html.

The [build log contains no meaningful 
warning|https://github.com/KengoTODA/unexpected-groovydoc-reproduction/runs/3025284625?check_suite_focus=true#step:5:23].
 I've confirmed that GroovyDoc 3.0.2 also reproduces this issue, so I guess 
that the change between v2 and v3 introduce this unexpected behavior.
