The language versions for ["mvn", "test", "-P", "unit-test", "-ntp"] is 8. Having a look at the Github Action workflow file here - https://github.com/apache/incubator-hugegraph-computer/blob/d2b95262091d6572cc12dcda57d89f9cd44ac88b/.github/workflows/ci.yml#L78C4-L85C16 shows that it should be JDK11.

I think this is because at this point -

	def find_language_setup_action(job_node: GitHubJobNode, lang_name: BuildLanguage) -> Language | None:
	"""Find the step that calls a language setup GitHub Actions and return the model.
	Parameters
	----------
	job_node: GitHubJobNode
	The target GitHub Actions job node.
	lang_name: BuildLanguage
	The target language used in the build.
	Returns

	Language | None
	The language model for the language setup GitHub Action or None.

	for callee in job_node.callee:
	model = callee.model
	# Check if the model implements the Language protocol.
	if isinstance(model, Language):
	if model.lang_name == lang_name:
	return model
	return None

we return the very first Setup Language step. However, in this project, they Setup Language step closest to the build command should be the correct one.
