Micronaut 4 Groovy projects fail Intellij compilation

[timyates]

Something in this PR has broken compilation with Groovyc and inject-groovy.

#9232

when d273fda is reverted then this test passes.

I am not sure why

From @paulk-asert

It probably isn't the usual case of two places using ClassHelper.make when a cached version is needed but rather one being a primary classnode (since we are compiling it)

[dstepanov]

Your test is failing becase the class is not found.
Please try your use case with resolveName changed to findClassNode. Otherwise this needs to be addressed with the Groovy team. All this is added so we can properly get the default annotation values (GroovyMappedStereotypesSpec).

[dstepanov]

So I looked a bit more, and I see a few issues:

• @timyates The test should have FileSystemCompiler.commandLineCompile(testDirectory.resolve("src/main/java/Usage.groovy").toString(), testDirectory.resolve("src/main/java/Annotation.groovy").toString())
• It looks like our code have added that resolution, because it's not possible to retrive the annotation default values from the ordinary ClassNode but it works with DecompiledClassNode
• The problem is in ClassNodeResolver#tryAsScript which calls CompilationUnit#addSource:

public SourceUnit addSource(final SourceUnit source) {
        String name = source.getName();
        source.setClassLoader(getClassLoader());
        for (SourceUnit su : queuedSources) {
            if (name.equals(su.getName())) return su;
        }
        queuedSources.add(source);
        return source;
    }

That one is not checking if the source is already in sources field.
