Java 无法解决android studio中的依赖关系，为什么会发生这种情况？

我关闭了我的android项目，突然当我想再次打开我的项目时，它给了我错误

错误：无法解析的依赖项 ':app@debugAndroidTest/compileClasspath'：无法解析 androidx。测试：runner:1.2.0

如果依赖项中有大写字母T，请使用下面的一个

androidTestImplementation 'androidx.test:runner:1.2.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'

发生这种情况是因为我创建了一个名为Test的模型类。是因为这个吗？在此之前，我可以打开应用程序，但在我创建了一个名为Test的类之后，我突然发现这些错误。是因为这个吗？你可能已经重构了你的代码，用“测试”代替了“测试”。
