Android Studio 2.0 - NoSuchAlgorithmException:SHA256WITHDSA签名不可用

Question

我运行的Android 2.0工作室预览3B并试图用"生成签名APK ......"从生成菜单.

我收到以下错误消息窗格:

:wear:packageRelease FAILED

Android Studio使用的是JRE 1.7.0_55-b13 x86_64.

我看到尝试使用较新的JVM来构建您的应用程序.建议.它有助于升级Java吗？或者我该如何解决这个问题？

我还没有看到任何地方(例如http://tools.android.com/recent)Android Studio 2.0需要Java升级.

我刚刚得到了Android Studio 2.0(稳定版)的完全相同的问题com.android.tools.build:gradle:2.0.0.

即使我的IDE使用JDK 1.8_u77运行,我仍然遇到了问题.

要修复它,去项目结构 > SDK位置>确保JDK的位置被设置为一个(至少1.8)最近的JDK!(在这篇文章发表时,最新的是1.8_u77).
