I am new to gradle but learning quickly. I need to get some specific JARs from logback into a new directory in my release task. The dependencies are resolving OK, but I can't figure out how, in the release task, to extract just logback-core-1.0.6.jar and logback-access-1.0.6.jar into a directory called 'lib/ext'. Here are the relevant excerpts from my build.gradle.

dependencies {
    ...
    compile 'org.slf4j:slf4j-api:1.6.4'
    compile 'ch.qos.logback:logback-core:1.0.6'
    compile 'ch.qos.logback:logback-classic:1.0.6'
    runtime 'ch.qos.logback:logback-access:1.0.6'
    ...
}
...
task release(type: Tar, dependsOn: war) {
    extension = "tar.gz"
    classifier = project.classifier
    compression = Compression.GZIP

    into('lib') {
        from configurations.release.files
        from configurations.providedCompile.files
    }

    into('lib/ext') {
        // TODO:  Right here I want to extract just logback-core-1.0.6.jar and logback-access-1.0.6.jar
    }
    ...
}

How do I iterated over the dependencies to locate those specific files and drop them in the lib/ext directory created by into('lib/ext')?
