请帮忙.我正在设置我的android studio测试时非常可怕.
我已经下载了计算器示例,从黄瓜github练习cumcumber代码测试. https://github.com/cucumber/cucumber-jvm/tree/master/android(其中一些品牌btw非常扼流自命名)
我试着在Android工作室使用它.该程序运行完美(耶！).然而,测试没有.我有一个非常可怕的消息,每次我运行时都会困扰我.
*To run dex in process, the Gradle daemon needs a larger heap.
It currently has approximately 910 MB.
For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB.
To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties.
For more information see https://docs.gradle.org/current/userguide/build_environment.html
Error:Error converting bytecode to dex:
Cause: Dex cannot parse version 52 byte code.
This is caused by library dependencies that have been compiled using Java 8 or above.
If you are using the 'java' gradle plugin in a library submodule add
targetCompatibility = '1.7'
sourceCompatibility = '1.7'
to that submodule's build.gradle file.
Error:1 error; aborting

它的目标兼容性和源兼容性我遇到了麻烦(尚未完成剩下的工作)
这是gradle构建：正如您所看到的,我已将兼容性更改为1.7

无法运行的测试：

现在我试过这个：
Error when using a jar in my project
还有这个：
Is it possible to use Java 8 for Android development?
还有这个：
Gradle sourceCompatibility has no effect to subprojects
在项目gradle和app gradle中.但我正在考虑它是唯一的测试…这些将无济于事,它与依赖关系有关,因此我很困难.谁能帮忙！提前致谢
解决方法:
您有一个依赖项,不清楚哪个是为Java 8编译的,并且您已在构建中指定了Java 7.
错误消息这是由使用Java 8或更高版本编译的库依赖项引起的.他们是关键吗？
我的方法是将Java版本更改为8.如果不能解决问题,请减少问题.也就是说,从没有依赖项和代码的新项目开始,添加非常小的部分,直到找到导致上述错误的内容.
也就是说,应用Galls Law：
