Cannot resolve junit:junit:4.13.2

This error message usually occurs when the JUnit dependency is not properly added to your project. Here are a few steps you can take to resolve this issue:

1. Make sure that you have added the JUnit dependency to your project's build file (e.g. build.gradle or pom.xml). For example, in Gradle, you can add the following line to your dependencies block:

testImplementation 'junit:junit:4.13.2'

2. If you have already added the dependency, try running a clean build of your project. In Android Studio, you can do this by selecting "Build" -> "Clean Project" from the menu.

3. If the above steps don't work, try deleting your project's local Gradle cache and rebuilding the project. On Windows, the cache is typically located in "C:\Users\<username>\.gradle\caches". On Mac/Linux, it's usually located in "~/.gradle/caches".

Hopefully one of these steps will help resolve the issue!
