I just released plexus-archiver version 2.10-beta-1 to maven central.
This is a "technology preview" of the multithreaded Zip feature I have
been adding to commons-compress for the last few weeks, and will
basically use all available CPU cores when compressing the archive.
To test/use this feature, you can add the following clause some plugins:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.5.3</version>
<dependencies>
<dependency>
<groupId>org.codehaus.plexus</groupId>
<artifactId>plexus-archiver</artifactId>
<version>2.10-beta-1</version>
</dependency>
<dependency>
<groupId>org.codehaus.plexus</groupId>
<artifactId>plexus-io</artifactId>
<version>2.4.1</version>
</dependency>
</dependencies>
</plugin>
This applies to maven-war-plugin, maven-jar-plugin, maven-ear-plugin,
maven-assembly-plugin, maven-dependency-plugin and probably a few
others too.
The feature is basically "done". commons-compress 1.10 has not yet
been released, and the moment this happens there will be a non-beta
version of plexus-archiver. This version contains a shaded-snapshot
version of commons-compress.
Please note that if your project basically produces a 30K jar file,
there is not much to be expected from this upgrade. The larger your
zip/jar/ear/war files, the more you can expect. And, of course, you
can use this as an argument towards your boss to get a 6 core CPU.
Feedback appreciated !
In other news, the java 1.6 version "3.0" was also released today,
which contains "snappy" compression. 3.0 does not yet contain the
parallel feature.
