java - 如何修复 'ERROR: Failed to resolve: androidx'？

Question

我再次回去工作以完成我的申请，但是当应用程序开始同步时，它给了我

Failed to resolve: androidx Affected Modules: href="openFile:D:/.android/Step View/Application/Source Code/app/build.gradle">app

我看到这样的问题，但它对我不起作用。抱歉我的英语不好。

这是我的等级。应用程序

就我而言，这是由 build.gradle 中的拼写错误引起的:

//androidTestImplementation 'androidx  .test.espresso:espresso-core:3.2.0' // wrong!
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

我通过使用 stacktrace 选项从命令行运行 Gradle 包装器发现了错误:

./gradlew clean build --stacktrace

输出:

Caused by: org.gradle.internal.resolve.ModuleVersionNotFoundException: Could not find androidx. test.espresso:espresso-core:3.2.0.
