When changing file name, rename seems a good approach. When changing path you can override eachFile and modify the destination path.

This works pretty well.

    copy {
    from("${sourceDir}") {
        include 'modules/**/**'
    }
    into(destDir)
    eachFile {details ->

        // Top Level Modules
        def targetPath = rawPathToModulesPath(details.path)
        details.path = targetPath
    }
}
....
def rawPathToModulesPath(def path) {
// Standard case modules/name/src -> module-name/src
def modified=path.replaceAll('modules/([^/]+)/.*src/(java/)?(.*)', {"module-${it[1]}/src/${it[3]}"})
return modified
}
