Renaming output file

I all!

I want to rename my output file that is "examplemod-1.0.0.jar"

to a new filename containing mc version: "examplemod-1.20.1-1.0.0.jar"

What i have done is to copy the output file to a new file with new filename

and then delete the old file.

This works but i'd like to know what is the correct way to do it.

this is my code:

tasks.named('build') {
	doLast {
		
		def orig_file = "${buildDir}/libs/${mod_id}-${mod_version}.jar"
		println "orig_file: ${orig_file}"
		
		def source_file = "${buildDir}/libs/${mod_id}-${minecraft_version}-${mod_version}.jar"
		println "source_file: ${source_file}"

	    copy {
	    	from "${orig_file}"
	    	into "${buildDir}/libs"
	    	rename "${mod_id}-${mod_version}.jar", "${mod_id}-${minecraft_version}-${mod_version}.jar"
	    }
	    
	    delete "${orig_file}"

		def dest_client_dir = "$projectDir/../client-${minecraft_version}-${forge_version}/mods/"	    
		println "dest_client_dir: ${dest_client_dir}"
		
		def dest_server_dir = "$projectDir/../server-${minecraft_version}-${forge_version}/mods/"	    
		println "dest_server_dir: ${dest_server_dir}"


	    copy {
	    	from "${source_file}"
	    	into "${dest_client_dir}"
	    }

	if("${displayTestLine}"!="displayTest=\"IGNORE_ALL_VERSION\"") 
	    copy {
	    	from "${source_file}"
	    	into "${dest_server_dir}"
	    }
	}
}

thx
