Cannot expose test class from one subproject to another

[juankb1024 (Juan Carlos)]

I’ve been trying to do what this answer says to expose some common test classes from subproject “B” to “C” but it fails to compile with NoClassDefFoundError.

Gradle test classes needed in another sub-project

Hi, As explained here, a ProjectDependency is a dependency on the default configuration of a particular project. For a java project, the default dependency is an extension of the runtime dependency (as stated in here). In your case, you want to depend on the testRuntime dependency, with something like compile project(':A:B:C', configuration: 'testRuntime') If this doesn’t suit you, you can always create a custom configuration, and depend on it: in :A:B:C project: configurations{ fooConf } t…

I also tried this method but also failed:

Multi-project test dependencies with gradle

I’m using gradle 7.2.

How can I consume those classes?

Hi @juankb1024
can you share a bit more about your project structure ?
What classes do you want to share between projects ?
are they some test fixtures that are written in project B, and you want them as well to write some of your tests in project C, or ?

eventually you’ll want (in project C) something like (snippet in groovy)

dependencies { testImplementation project(":B") } 

to have classes on the default configuration of project B available to the classpath used to compile tests of project C. But the exact syntax will depend on whether those classes are bundled in the default configuration of project B or not, hence the question about the setup of projects B and C
