Gradle: retrieve only one of multiple published artifacts?

Question

I\'ve got an Ivy repository with multiple published artifacts, something like this:

/mygroup/mymodule/1.1.1/mymodule-1.1.1.jar
/mygroup/mymodule/1.1.1/mymodule-c         


        

Answer 1

The Ivy module descriptor doesn't assign the artifacts to different configurations, hence it's not possible to retrieve them independently. If all you want is to only put one of the two artifacts on the compile class path, something like the following should work:

configurations {
    mymodule
}

dependencies {
    mymodule 'mygroup:mymodule:1.1.1'
    compile configurations.mymodule.filter { it.name == 'mymodule-client-1.1.1.jar' } 
}

Answer 2

Managed to find the appropriate line after a lot of trial and error:

compile ('mygroup:mymodule:1.1.1:client@jar')

I think it only works because the "client" is an extension of the module name (called a classifier apparently). If I'd had something named differently, I'm not sure how I'd have resolved it.

I found the example that gave me the clue here: http://scratchpad.pietschy.com/gradle/dependency_management.html

20.2.2.2. Artifact only notation An artifact only notation creates a module dependency which only downloads one artifact file. The notation for such a dependency follows the pattern: [group]:[artifact]:[version]@[extension] or [group]:[artifact]:[version]:[classifier]@[extension]. For example:

dependencies { compile "org.apache.ant:ant-junit:1.7.0@jar" }
