こちらの質問に似ていますが、やや状況が違いますので、新たに質問させていただきます。
MonacaでCordova5.2にアップデートしたらAndroidビルドに失敗してしまいます

2016年3月頃にリリースビルドできたファイルをインポートし、一切の変更を加えず、再度ビルドしようとしたところ、以下のような文言のエラーが返され、ビルドできませんでした。

一度正しくビルドできたものを、全く変更せず、手順も同じようにリリースビルドをしようとした際、ビルドできなくなることなど、あるのでしょうか。あった場合、どのような原因で、どう対応すれば良いでしょうか。

お教えいただければ幸いです。

ビルドに失敗しました
アプリのビルドに失敗しました。ビルド設定に間違いがある可能性があります。下記の設定を再確認してください。
・AndroidManifest.xmlは正しく記述されていますか？
・キーストアの設定は正しいですか？
設定を修正した後、再度ビルドを実行してください。

なお、細かいエラーとして、以下の内容が出力されました。
