TrueZIP Maven Plugin

This plugin uses TrueZIP which treats archives as a virtual file systems. Each archive file is considered as a directory of a file system.

Similar to assembly and clean plugins, FileSet is used extensively to manipulate file system type actions.

The following contains some brief examples on how to use the truezip goals.

Remove

The remove goal can remove files from an existing archive. The below example shows how to remove any pom.properties file under the META-INF/maven directory of the archive.

  <build>
    [...]
    <plugins>
      [...]
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>truezip-maven-plugin</artifactId>
        <version>1.2</version>
        <executions>
          <execution>
            <id>remove-a-file</id>
            <goals>
              <goal>remove</goal>
            </goals>
            <phase>package</phase>
            <configuration>
              <fileset>
                <!-- note how the archive is treated as a normal file directory -->
                <directory>${archive}/META-INF/maven</directory>
                <includes>
                  <include>**/pom.properties</include>
                </includes>
              </fileset>
            </configuration>
          </execution>
          [...]
        </executions>
      </plugin>
      [...]
    </plugins>
  </build>

  <properties>
    <archive>path.to.an.archive</archive>
  </properties>

Copy

The copy goal can copy files in and out of the archive. The below example shows multiple executions:

Copy files from the archive to a real file system with option to rename the file on the fly. This is similar to the maven-assembly-plugin's files configuration.
Copy files from the archive to a real file system using FileSet interface.
Copy files from the real file system to the archive.

  </build>

Pack/unpack from command line

Use cp goal to copy an archive/directory to another archive/directory.

The following example shows how to unpack an archive to a directory
```
mvn truezip:cp -Dfrom=apache-maven-2.2.1-bin.tar.gz -Dto=.
```

The following example shows how to pack a directory to an archive

mvn truezip:cp -Dfrom=apache-maven-2.2.1 -Dto=apache-maven-2.2.1.zip

The following example shows how to transfer an archive to another archive

mvn truezip:cp -Dfrom=apache-maven-2.2.1-bin.tar.gz -Dto=apache-maven-2.2.1-bin.zip

Move

The move goal can move a file in, out, or within the archive. The below examples show how to move an archive's file to another location in the archive. Note that the location can be outside of the archive as well.

  <build>
    [...]
    <plugins>
      [...]
      <plugin>
        <groupId>org.codehaus.mojo</groupId>

            <goals>
              <goal>move</goal>
            </goals>
            <phase>package</phase>
            <configuration>
              <!-- move a archive file to another directory in the same archive -->
              <from>${archive}/META-INF/MANIFEST.MF</from>
              <to>${archive}/META-INF2/MANIFEST.MF</to>

              <!-- use this if you want to move it out of the archive -->
              <!--to>${project.build.directory}/MANIFEST.MF</to-->
            </configuration>
          </execution>
          [...]
        </executions>
      </plugin>

    </plugins>
