Android Studio Gradle發行版構建失敗-帶有Minify選項

Question

我最近嘗試在發布模式下構建我的Android Studio項目之一。 我啟用了縮小功能，並為我的構建使用了有效且有效的密鑰庫。

現在，當Gradle嘗試構建我的項目時，它沒有任何警告，但是一旦嘗試從我的classes.jar計算哈希值，便失敗了。 由於我完全沒有錯誤，因此我使用--stacktrace選項再次構建了它。 這是我獲得的gradle控制台輸出：

我以前從未遇到過如此奇怪的錯誤，並且只有在啟用proguard來縮小我的項目時才會發生。 但是顯然我需要proguard，因為我想在發布情況下混淆我的代碼。

還有其他人遇到過這樣的錯誤嗎？ 我能做什么？ 不久前，我使用相同的設置並最小化了，就很好地構建了該項目。 我的proguard文件完全空白。

謝謝你的幫助。

Answer 1

一種可能的答案是，您現在在build.gradle（應用程序）中使用的Google服務的8.1.0版本是Google意外破壞的。 我已經將我的版本降級到7.8.0了。

例

compile 'com.google.android.gms:play-services-base:7.8.0'
compile 'com.google.android.gms:play-services-ads:7.8.0'

可能還有其他答案，但這是我列表中的最高答案

通常，即使有額外的輸出，也無法清楚地指出出什么問題。
