question
monaca
monacaでのビルドできない(Androidアプリのリリースビルド)
原因となるエラーは以下の部分です。

```

    * What went wrong: A problem occurred evaluating root project 'android'.
    > release-signing.properties: Missing key required "keyAlias"
    
```

署名用の鍵設定をしていないことが原因と考えられます。  
Monacaのドキュメントの[ステップ 2 : Android キーストア ( KeyStore )
の設定](https://docs.monaca.io/ja/manual/build/build_android/)を確認してください。
