Some questions about the assembly plugin

[Rui Vilão]

Hi there,

I'm trying to do the following:

I want to be able to specify in what phase the maven assembly plugin runs.
Is this possible? I'm only able to run it using mvn assembly:assembly,
otherwise it won't run.
I've tried with 2.2-beta-5 and 2.1 with no success.

     <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-assembly-plugin</artifactId>
        <version>2.2-beta-5</version>
        <configuration>
          <descriptors>
            <descriptor>release.xml</descriptor>
          </descriptors>
          <executions>
            <execution>
              <id>make-assembly</id>
              <phase>package</phase>
              <goals>
                <goal>single</goal>
              </goals>
            </execution>
          </executions>
        </configuration>
      </plugin>

Does anyone had this problem?

Thanks in advance,

Rui Vilão
