Gradle: Override transitive dependency by version classifier

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"
}
