请帮忙。我在为 android studio 设置测试时经历了一段非常糟糕的时光。
我已经从 cucumber github 下载了计算器示例来练习 cumcumber 代码测试。https://github.com/cucumber/cucumber-jvm/tree/master/android(顺便说一句,其中一些品牌的名字非常奇怪)
我尝试将它与 Android studio 一起使用。该程序运行完美(耶!)。然而测试却没有。我有一个非常可怕的信息,每次我运行它时都会困扰我。
*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

我在目标兼容性和源兼容性方面遇到了麻烦(尚未完成其余部分)
这是 gradle 构建:如您所见,我已将兼容性更改为 1.7

现在我已经尝试过这个:
在我的项目中使用 jar 时出错
和这个:是否可以使用Java 8进行Android开发?
和这个:Gradle源码兼容性对子项目没有影响
在项目 gradle 和应用程序 gradle 中。但我认为它只是进行测试......这些不会有帮助,它与依赖关系有关,为此我陷入了困境。任何人都可以帮忙吗!提前致谢
