Description

There was a new method introduced:

org.apache.maven.project.DefaultProjectBuilder.getModelCache()

this breaks the https://github.com/takari/polyglot-maven extension that fails with a NPE if running on maven 3.9.0

Also this probably should be fixed there, this can be mitigated in maven by doing the following:

private ModelCache createModelCache(RepositorySystemSession session) {
    if (modelCacheFactory == null) {
        
        return null; // or do whatever DefaultModelCache does here
    }
    return modelCacheFactory.createCache(session);
}
