Unable to run JUnit test cases after converting project to Gradle in Eclipse

Question

I was using Maven to manage my project in Eclipse, but decided that Gradle looked like something that could end up benefiting me more. I'm trying to implement a CI/CD pipeline, but want to check certain thing (unit test success, and code coverage for example). After converting my project using

gradle eclipse

I find that I am no longer able to run JUnit test cases via the context menu

Right Click -> Run As... -> JUnit Test

With the following error

Class not found <package>.<class>

But when I run

gradle test

All of them pass, but don't give me any more information (which were run, which ones failed, which ones errored out).

By switching to a Gradle project, can all tasks only be run in the context of Gradle now? There are no errors reported in Eclipse, and building works fine. I have verified that the files are in the expected locations.

Answer 1

I was able to solve this doing the following steps.

1. Close the project in eclipse
2. Delete the project from the eclipse workspace (not from the file system)
3. Close eclipse
4. Open command line terminal
5. Run gradle cleanEclipse eclipse
6. Open eclipse
7. Import as a gradle project

At that point, everything was set up again.

Answer 2

This was happening to me as well. I was comparing Gradle to Maven, and I couldn't right mouse click on my Test.java file and Run as JUnit Test. My project had originally started as a Maven project, and I had converted it to Gradle. The problem was due to the old JUnit Run Configurations. All I did was go into Run Configurations and delete all the ones for JUnit. After I did this it started working. Hope this helps as the gradle eclipseClean eclipse didn't work for me.

您可以在较新的Eclipse IDE实例中单步执行“作为gradle项目导入”。
