アンドロイドProGuardの構築に失敗しました：重複zipエントリ

Question

リリースを組み立てながら、私はこのエラーを取得しています：

警告：例外処理タスクにjava.io.IOExceptionながら：書き込めません[/ユーザ/ tuanchauict/PW// Android/xrmovies/app/build/app/build/app /アンドロイド/サポート/ v7/appcompat/R $（重複したzipエントリ[android/support/v7/a/a $ a.class ==アンドロイド/サポート/ v7/appcompat/R $] attr.class]）） ：app：transformClassesAndResourcesWithProguardForProdRelease FAILED

Answer 1

（OPに代わって投稿）。

問題の原因がわかりました。私はサードパーティ製のライブラリを使用しています。これは何とかサポートライブラリのRクラスが含まれています。それを取り除くとビルドが動作します。
