在Android Studio中编译错误

Question

我有以下build.gradle文件但是当我尝试运行代码时出现以下错误（错误发生是因为我在mysql库中添加，在build.gradle文件中的依赖项下看到）：

Error:Execution failed for task ':app:preDexDebug'.
com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1

这是我得到的完整输出：

我看过Error: finished with non-zero exit value2和Error when trying to integrate parse into Android app error: Error:Execution failed for task ':app:transformClassesWithDexForDebug'，但他们的解决方案并没有帮助。

这是我的傻瓜：
