Android Studio 和 Gradle

Question

我尝试在 Android Studio 中导入 Xabber (GitHub)，我执行了 git init 等。 现在我发现我可以启动该问题的应用程序 Gradle ，我到处都找过了，但找不到任何可以工作的东西..

问题是:

Error:Execution failed for task ':app:dexBetaDebug'.
> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1

所以我在这个http://www.alonsoruibal.com/my-gradle-tips-and-tricks/找到了解决方案.

诀窍在于您需要在 Java 库模块的 build.gradle 文件中包含以下内容。

apply plugin: 'java'
sourceCompatibility = 1.6
targetCompatibility = 1.6
