Maven maven-exec-plugin execution before zip packaging - eclipse

Question

I'm building a Maven+Tycho Eclipse RCP application and I would like to run my codesign maven-exec-plugin on OS X before the product is being compressed to zip and before the binary gets compressed for distribution in repository/binary.
So I suppose that the step should be somewhere between the compiling and packaging but I'm having a hard time just by trial and error.
Which lifecycle build phase should it be tied to?
My maven-exec-plugin looks like this at the moment (the app gets codesigned but after the zip has already been created):
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.2.1</version>
<executions>
<execution>
<id>exec</id>
<phase>package</phase>
<goals>
<goal>exec</goal>
</goals>
</execution>
</executions>
<configuration>
<executable>codesign</executable>
<workingDirectory>/tmp</workingDirectory>
<arguments>
<argument>-s</argument>
<argument>"My Developer ID"</argument>
<argument>-vvv</argument>
<argument>${project.build.directory}/products/${product-id}/macosx/cocoa/x86/MyApp/MyApp.app"</argument>
</arguments>
</configuration>
</plugin>

Answer 1

Use the prepare-package lifecylce phase in your execution block instead of the package lifecycle phase.
