Java – Gradle: Override transitive dependency by version classifier

dependency-managementgradleguavajavamaven

One of the dependencies declared in my project has a transitive dependency on 'com.google.guava:guava:15.0'. But my application deployed on WAS/Weblogic doesn't work due to a CDI issue which has been fixed in 'com.google.guava:guava:15.0:cdi1.0'. (same version, but with classifier) I need to tell gradle to use this jar during build and packaging. I am trying to figure on how we can ovrride this transitive dependency with a jar specific version classifier.

Tried the following approches:

  1. Added the dependency explicitly: compile 'com.google.guava:guava:15.0:cdi1.0'. But both jars got included in the resultant WAR.
  2. Added the dependency explicitly and defined a resolution strategy:

    configurations.all {
        resolutionStrategy {
            force 'com.google.guava:guava:15.0:cdi1.0'
        }
    }
    

    Even this didn't work.

  3. Defined a resolution strategy to check and change the version.

    configurations.all {
         resolutionStrategy.eachDependency { DependencyResolveDetails details ->
             if (details.requested.group + ":" + details.requested.name == 'com.google.guava:guava') {
                details.useVersion "15.0:cdi1.0"
                //details.useTarget "com.google.guava:guava:15.0:cdi1.0"
            }
        }
    }
    

    Even this didn't work.

Need your suggestions on how this issue can be tackled.

Currently classifiers are not yet taken into account when it comes to resolutionStrategies. A workaround for you might excluding the transitive Guava library when declaring your dependencies and adding the Guava cdi1.0 version explicitly:

dependencies {
    compile ("org.acme:someDependency:1.0"){
        exclude group: 'com.google.guava', module: 'guava'
    }       
    compile "com.google.guava:guava:15.0:cdi1.0"
}
