How to turn off jar compression in Maven

Question

Is there an option in Maven (2.0.9) to turn off jar compression for the entire operation? I'm using Maven both in the build server and in my work station and I'd like to disable jar compression on the work station builds (development only). However, I don't want to touch all the poms and create two versions for each.

Is there an option for turning off jar compression by environment variable, file or by touching a single pom.xml?

Answer 1

There is no such option in the standard plugin, See all options in the maven-jar-plugin page

Edit You can add an antrun task that will run after the package phase and then delete he created jar (or rename it) and re-create the jar from the classes directory. Then you can put compress="false" in the jar task definition - see here. I did similar thing using the proguard post processor.

Edit 2 Given Ran's new reason, the ant task will definite won't help to shorten the build time.

Answer 2

Well, you could define different jar plugin by profile. Would that be acceptable?

Answer 3

Apparently it's possible by defining this:

<profile><id>...</id>
  <build>
    <pluginManagement>
        <plugins>
            <plugin>
                <configuration>
                    <archive>
                        <compress>false</compress>

...(close all tags)

in the top-level pom.xml. As a side note - this didn't really solved my initial problem of the build taking too much time.

Answer 4

Add the following to the build.plugins section in your project's pom.xml file.

<plugin>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.2</version>
    <configuration>
        <archive>
         <compress>false</compress>
        </archive>
    </configuration>
</plugin>

This turns off jar file compression for your maven project.
