Android Studio: Failed to create MD5 HashFile
提问by Damen Tomassi
I am creating a simple android application... I ran into some kind of trouble when I updated gradle when I launched Android Studio and it prompted me too.
我正在创建一个简单的 android 应用程序...当我在启动 Android Studio 时更新 gradle 时遇到了一些麻烦，它也提示了我。
Upon the update completing I receive the following error:
更新完成后，我收到以下错误：
Error:Execution failed for task ':app:compileDebugJavaWithJavac'.
错误：任务 ':app:compileDebugJavaWithJavac' 的执行失败。
Failed to create MD5 hash for file '/Users/damenTomassi/AndroidStudioProjects/AstraeaDemo/app/src/main/res/libs/gson-2.3.1.jar'.
无法为文件“/Users/damenTomassi/AndroidStudioProjects/AstraeaDemo/app/src/main/res/libs/gson-2.3.1.jar”创建 MD5 哈希。
I used to have the GSON library in my project, however I no longer needed it so I removed it...
我曾经在我的项目中有 GSON 库，但是我不再需要它所以我删除了它......
Does anyone have any suggestions?

I had this issue today, and after wasting an hour trying everything else mentioned I updated my Android Studio to the latest release and got a different error message that the jar file did not exist. Checking my project this error was correct, I had,
我今天遇到了这个问题，在浪费了一个小时尝试了所有提到的其他内容之后，我将我的 Android Studio 更新到了最新版本，并收到了一条不同的错误消息，即 jar 文件不存在。检查我的项目这个错误是正确的，我有，
compile files('libs/activation.jar')
compile files('libs/mail.jar')
compile 'com.sun.mail:android-mail:1.5.5'
compile 'com.sun.mail:android-activation:1.5.5'
But did not have a file, libs/activation.jar, for some reason this use to work fine, but stopped working today. I change it to just,
但是没有一个文件，libs/activation.jar，由于某种原因，这个使用工作正常，但今天停止工作。我把它改成只是
compile 'com.sun.mail:android-mail:1.5.5'
compile 'com.sun.mail:android-activation:1.5.5'
and my build now works again. Odd, but I did try commenting out those lines before, but still got the error, so maybe updating Studio helped too, or I needed to do a combination of the above.
我的构建现在又可以工作了。奇怪，但我之前确实尝试过注释掉这些行，但仍然出现错误，所以也许更新 Studio 也有帮助，或者我需要结合上述内容。
Anyway problem solved and check that your jars actually existing in the libs directory.
无论如何，问题已解决并检查您的 jars 是否确实存在于 libs 目录中。

This seems to be a transient issue in gradle. I fixed it by killing the running gradle daemons (pkill -f gradle) and rebuilding.
这似乎是 gradle 中的一个暂时性问题。我通过杀死正在运行的 gradle 守护进程 ( pkill -f gradle) 并重建来修复它。
