How to run unit tests against multiple dependency versions

Question

I am writing a foo java library that has a dependency on bar:1.1+ . But the bar library has changed quite a bit over time, and I want my library to be compatible with each version of bar ( 1.1 ... 1.10 ).

Therefore, I would like (during CI) to run each of my unit tests using the classpath, including bar:1.X , with each version available to bar .

I use gradle and junit / spock, but I'm open to solutions with options.

To the right, I can duplicate gradle test cases, but this is rather cumbersome, and test results can be difficult to aggregate. Ideally, I would determine next to my test in which versions of the bar it should work, for example:

 @RunWith("com.acme:bar:1.1..1.10") public class MyTest { ... } 

But I do not find for this tool / runner.

This is due to Maven and not sure how it will comply with CI, but it can help you get started.

One option might be to use the archetype Maven <- Additional Information

Using mvn archetype:generate , you can generate a project with a dynamic version

 mvn archetype:generate -DarchetypeGroupId=<archetype-groupId> -DarchetypeArtifactId=<archetype-artifactId> -DarchetypeVersion=<archetype-version> -DgroupId=<my.groupid> -DartifactId=<my-artifactId> -Dversion=<custom-version>
