Android 任务执行失败'；应用程序：dexDebug'；,android,Android,我最近尝试在我的应用程序上测试本地后端支持，但遇到了一些gradle构建问题。下面是我得到的错误： Error:Execution failed for task ':app:dexDebug'. com.android.ide.common.process.ProcessException:org.gradle.process.internal.ExecException:process'command'/Library/Java/JavaVirtualMachines/jdk1.8.0_4

我试图删除多余的依赖项，但没有成功。我想知道你们是否能给我一些帮助！非常感谢您的帮助

我找到了一个解决办法。我补充说

multiDexEnabled true

要更改defaultconfig，请执行以下操作：

defaultConfig {
    //applicationId
    minSdkVersion 14
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"

    multiDexEnabled true
}

不久前我也遇到过类似的情况——这可能与您的问题无关——但Android Studio不太支持Java 1.8。我必须恢复到1.7版本才能正确编译我的项目。我有类似的问题，使用构建工具版本23预览版对我有效。我已经添加了。但这对我不起作用。你能建议一下吗？
