奇妙な振る舞いです。プロジェクトをパッケージ化できる場合もありますが、ほとんどの場合はパッケージ化できません。問題は次の場所で発生しandroid:dexます：

そうですね、そのログに基づいて、ビルダーはフォルダーをdexしようとする直前に、フォルダー内のすべてのファイルを削除していると言えます。したがって、そこに何もないため、dexは失敗します。ただし、maven-clean-pluginをどこでも呼び出していないので、なぜこれが発生しているのかわかりません。mvn cleanを呼び出すとビルドが機能する場合にも同様の問題が発生するのを見てきましたが、;mvn installを呼び出すと機能しません。mvn clean installただし、これは、人々がクリーンなプラグインを自分で呼び出している大規模なカスタムビルドでのみ見られます。ただし、原因がわからない場合でも、状況に役立つ可能性があります...

編集：申し訳ありませんが、それは私にとってまだ早いです。問題はクリーンではありません。問題は、コンパイラプラグインが実行されていないことです。クリーンアップ後、通常、生成する必要のあるリソースがあり、コードがコンパイルされ、クラスがデックスされます。.classファイルを生成することは決してないので、dexするものは何もありません。

生成さRれたファイルはパッケージ宣言com.example.test（私のプロジェクトのgroupId）を使用し、クラスでそれにアクセスしようとしましたcom.example.test.gui.MainActivity。com.example.test.Rしたがって、明示的にインポートする必要がありました。
