Gradle Plugin: Circular Dependency

[wabuMike]

How to reproduce

1. Include the Gradle Plugin in an existing Quarkus Gradle project as described in https://github.com/smallrye/smallrye-open-api/blob/main/tools/gradle-plugin/README.md#via-gradle-includebuild
2. On the existing project, execute the Gradle task "generateOpenApiSpec" with ./gradlew generateOpenApiSpec. Gradle will give you the error:

FAILURE: Build failed with an exception.

• What went wrong:
  Circular dependency between the following tasks:
  :compileJava
  +--- :quarkusGenerateCode
  | --- :processResources
  | --- :generateOpenApiSpec
  | +--- :compileJava ()
  | +--- :quarkusGenerateCode ()
  | --- :quarkusGenerateCodeDev
  | --- :processResources ()
  --- :quarkusGenerateCodeDev ()

(*) - details omitted (listed previously)

• Try:

Run with --stacktrace option to get the stack trace.
Run with --info or --debug option to get more log output.
Run with --scan to get full insights.

Solution

The problem is with those lines in SmallryeOpenApiPlugin.java:

project.getTasks().named(sourceSet.getProcessResourcesTaskName(), ProcessResources.class)
                .configure(t -> {
                    t.dependsOn(genTaskName);
                    t.from(project.getTasks().getByName(genTaskName).getOutputs().getFiles());
                });

When I remove those lines, the task runs as expected. I suppose those lines have their purpose and although removing them works for my use case, it might break other use cases.

@snazy, do you have any ideas on this one? My Gradle expertise isn't quite up to par :-)
