Gradle: Override transitive dependency by version classifier

Question

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 out how we can override this transitive dependency with a jar specific version classifier.

Tried the following approaches:

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"
}
