java - コード カバレッジ全体に影響を与えることなく、生成されたソースをコード カバレッジから除外する

Question

コード カバレッジの数値がかなり低いプロジェクトがあります。詳しく調べてみると、jacoco のコード カバレッジの統計が、src ではなくターゲット ディレクトリに依存していることがわかりました。

target/generated-sources/delombok/com/

ターゲット ディレクトリを除外すると、カバレッジは 0% 低下します。そのため、コード カバレッジは、ターゲット フォルダーではなくコード (src) に対して測定されることになっています。以下は、SonarQube のスクリーンショットです。

問題は、コード カバレッジがターゲットではなく src で測定されるようにするにはどうすればよいかということです。

以下は、依存関係のない pom です。

Answer 1

OK、Lombok Maven プラグインは、Maven ビルド中にソース フォルダーのリストを変更します。これが、target/generated-sources/delombokフォルダーが SonarQube によってソース フォルダーとして認識される理由です。

SonarQube が独自のソース ファイルのみを考慮するようにするには、次のプロパティを POM に追加する必要があります。

<properties>
  <sonar.sources>src/main/java</sonar.sources>
</properties>

これで問題は解決します。
