Unzip dependency in maven - maven-2

Question

I have the following dependency in maven
<dependency>
<groupId>org.hyperic</groupId>
<artifactId>sigar-dist</artifactId>
<version>1.6.5.132</version>
<type>zip</type>
</dependency>
This creates sigar-dist-1.6.5.132.zip in my repository.
I have seen this question here, however I still can't make it work.
How can I unzip the sigar-dist.zip and place the content in a directory in my project? What is the mvn call I have to do to make it work?

Answer 1

You can do it with dependencies:unpack-dependencies:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.2</version>
<executions>
<execution>
<id>unpack-sigar</id>
<phase>package<!-- or any other valid maven phase --></phase>
<goals>
<goal>unpack-dependencies</goal>
</goals>
<configuration>
<includeGroupIds>org.hyperic</includeGroupIds>
<includeArtifactIds>sigar-dist</includeArtifactIds>
<outputDirectory>
${project.build.directory}/wherever/you/want/it
<!-- or: ${project.basedir}/wherever/you/want/it -->
</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
