unnecessary java file extracted when compile AOSP with codeql

Hi
I'm trying to run CodeQL on AOSP with this command:
codeql database create new-database --working-dir=./ --source-root=./ --language=java --command='make services'
many unnecessary java files were extracted by codeql in output/soong/.intermediates, some javac-extractor logs are as following:

```
My question is how can I exclude these unnecessary java files while compile AOSP?

まず、報告された `codeql database create` コマンドを AOSP の `make services` ビルドで再現し、`output/soong/.intermediates` 配下の Java 抽出ログを調べます。生成されたファイルが想定された入力かどうかを確認し、それらを除外するためにサポートされている方法を特定します。再現可能な除外ワークフローを文書化または検証できれば完了です。
