  "message": "Cache projectsUsingPlugin list to avoid O(N²) reactor scan\n\nInstallMojo.execute() computes the list of reactor projects using\nthe install plugin on every module invocation by streaming over all\nprojects and calling getPluginsAsMap() for each one. In a 4383-module\nreactor, this produces ~19.2M filter evaluations (4383² calls).\n\nJFR profiling shows this as 5.6% of total CPU time, all in\nPluginContainer.getPluginsAsMap() called from usingPlugin().\n\nFix: cache the computed list in the first reactor project\u0027s plugin\ncontext on first invocation. The list is invariant during a build —\nwhich projects have the install plugin configured does not change\nbetween module invocations. This turns O(N²) into O(N).\n\nCo-Authored-By: Claude Opus 4.6 \u003cnoreply@anthropic.com\u003e\n",
