Question

StackOverflowで質問をして以来、長い年月が経ちました。私はほとんど毎日それを使用しますが。とにかく ;ここに行く：

最近私はAPI 23に切り替えました。私を強制的に使用して

useLibrary 'org.apache.http.legacy'

私のプロジェクトは正常にコンパイルされ、デバッグモードのすべてのテストデバイスで正常に動作します。 今日は本番に私のプロジェクトを持参する必要があるとProGuardのは

（..）\ビルド\中間体\クラス、ProGuardの\リリース\のclasses.jar」のハッシュを計算することができませんと叫びます他のエラーや警告はありません。以前はありましたが、私はそれらを取り除きました。 Apacheライブラリの重複コピーを取り除くように。ここで

は私のGradleファイルです：

Answer 1

Iagreenが彼のコメントで指摘したように、私はgradlewコマンドラインユーティリティを使用してより詳細なエラーを取得しました。 JAVA_HOME変数に問題があることが判明しました。解決済み。
