java - multidex 应用程序在尝试运行仪器测试时出现 ZipException : duplicate entry for junit,

Question

尝试运行仪器测试时，出现此错误:

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebugAndroidTest'.
    com.android.build.api.transform.TransformException:
    java.util.zip.ZipException:
        duplicate entry:
            org/junit/ClassRule.class

但有时重复条目是:

        duplicate entry:
            junit/extensions/ActiveTestSuite$1.class

这显然是正确的:Control-N -> 输入ClassRule 显示:

1. C:\Users\me\.gradle\caches\modules-2\files-2.1\junit\junit\4.12\a6c32b40bf3d76eca54e3c601e5d1470c86fcdfa\junit-4.12-sources.jar!\org\junit\ClassRule.java
2. C:\Users\me\.gradle\caches\modules-2\files-2.1\junit\junit-dep\4.10\64417b3bafdecd366afa514bd5beeae6c1f85ece\junit-dep-4.10.jar!\org\junit\ClassRule .class (反编译的.class文件，字节码版本:49.0(Java 5.0)

搜索ActiveTestSuite给出3个结果，全部位于C:\Users\me\.gradle\caches\modules-2\files-2.1\junit\

有没有办法查看依赖关系图？我评论了 app/build.gradle 的依赖项部分中所有相关的 junit:

Answer 1

您需要做的就是将以下行添加到我们的依赖项列表中:

 testCompile "junit:junit:4.12'

然后，通过在 app/build.gradle 中添加以下 block ，强制此版本的 Junit 依赖于整个项目:

configurations.all{
    resolutionStrategy.force 'junit:junit:4.12'
}

这将解决您所有的依赖冲突。
