错误：任务“：app：TransformClassesWithDexForDebug”html" target="_blank">执行失败。com.android.build.api.transform.transformException：java.lang.runtimeException：com.android.ide.common.Process.processException：java.util.concurrent.executionException：com.android.ide.common.processException：org.gradle.Process.internal.execexception：Process“command”C:\program files\java\jdk1.7.0_79\bin\java.exe“已完成，退出值为非零1

上部的错误是由许多原因造成的。所以我可以提出为什么这个错误发生和如何解决它。

原因1：类文件名重复

解决方案：

当您将一些类文件重构为库项目时。并且当您写入类文件名称时，请再次检查您没有任何重复的名称

解决方案：

打开Task Manager并停止其他不常用的应用程序，这样就可以释放空间，解决outofmemory问题。

原因5：问题是您的方法计数超过了65k。

defaultConfig {
        ...
        multiDexEnabled true
    }

dependencies 
    {
       compile 'com.android.support:multidex:1.0.0'
    }
