How to Compress/Decompress tar.gz files in java

Can anyone show me the correct way to compress and decompress tar.gzip files in java i've been searching but the most i can find is either zip or gzip(alone).

Answer

My favorite is plexus-archiver - see sources on GitHub.

Another option is Apache commons-compress - (see mvnrepository).

With plexus-utils, the code for unarchiving looks like this:

final TarGZipUnArchiver ua = new TarGZipUnArchiver();
ua.setSourceFile(sourceFile);
destDir.mkdirs();
ua.setDestDirectory(destDir);
ua.extract();

Similar *Archiver classes are there for archiving.

With Maven, you can use this dependency:

<dependency>
  <groupId>org.codehaus.plexus</groupId>
  <artifactId>plexus-archiver</artifactId>
  <version>2.2</version>
</dependency>
