java - Android gradle执行失败于:myapp:dexDebug

Question

我的gradle执行失败，并显示以下错误消息。我在SO上搜索了许多其他答案，建议这样做:

dexOptions {
        preDexLibraries = false
    }   

有人说这可能是内存错误，有人说可能是依赖项可能已经包括我要编译的依赖项之一。我将以下错误消息与build.gradle文件一起包括在内，您可以在其中查看我正在使用的依赖项。任何帮助深表感谢!

任务':app:dexDebug'的执行失败。

com.android.ide.common.internal.LoggedErrorException: Failed to run command: /Applications/Android Studio.app/sdk/build-tools/android-4.4W/dx --dex --num-threads=4 --output ... Error Code: 137

Answer 1

dx的运行需要产生新的VM。创建失败，请检查是否有足够的内存和/或设置defaultXmx = -Xmx512m(或更低)。请在此处也查看答案Android gradle build script returns error 137 in preDexDebug
