我也尝试使用最新版本的Gradle！

我没有足够的代表来评论，但是....

我今天遇到了这个问题。我的情况是，这个项目在Mac上运行得很好。然而，我需要让它在windows系统上运行。在我的Android\app\build.gradle文件中，我设置了一个getPassword方法，使我可以很容易地签署我的apk。在getPassword方法中,我调用了以下内容：

commandLine 'security', '-q', 'find-generic-password', '-a', currentUser, '-s', keyChain, '-w'

我注释掉了对getPassword方法的所有引用，它开始工作时没有出现任何问题。

问题的根源是mac使用的“安全”命令行工具在Windows上不可用。由于我现在也需要使用windows box，所以我在外部凭据文件中配置了密码。
