It is worth nothing that the accepted answer filters the Configuration as a FileCollection so within the collection you can only access the attributes of a file. If you want to filter on the dependency itself (on group, name, or version) rather than its filename in the cache then you can use something like:

task copyToLib(type: Copy) {
  from findJarsByGroup(configurations.compile, 'org.apache.avro')
  into "$buildSrc/lib"
}

def findJarsByGroup(Configuration config, groupName) {
  configurations.compile.files { it.group.equals(groupName) }
}

files takes a dependencySpecClosure which is just a filter function on a Dependency, see: https://gradle.org/docs/current/javadoc/org/gradle/api/artifacts/Dependency.html
