Maven-gae-plugin 0.9.4: no version available for org.codehaus.plexus:plexus-archiver:jar-- Help me explain the solution of the bug

Question

This bug was closed on github, https://github.com/maven-gae-plugin/maven-gae-plugin/issues/39 however i don't understand its fixing, and when i execute gae goal such as mvn gae:update it always gives me the same problem. could anyone explain the root cause of this problem based on its fixing?

For your info, i copy-paste the original problem and its fixing here:

From this morning I continue to get this error:

Failed to execute goal net.kindleit:maven-gae-plugin:0.9.4:unpack (execution2) on project gui: Execution execution2 of goal net.kindleit:maven-gae-plugin:0.9.4:unpack failed: Plugin net.kindleit:maven-gae-plugin:0.9.4 or one of its dependencies could not be resolved: Failed to collect dependencies for net.kindleit:maven-gae-plugin:jar:0.9.4 (): No versions available for org.codehaus.plexus:plexus-archiver:jar:[1.2,3.0) within specified range

.. and I am stuck with this plugin at the moment!

the fix is:

.. and I added the "-U" option to the command I use to use: mvn clean verify .. it becomes: mvn -U clean verify

Thanks in advance.

If it can help someone, here is my solution for the error "No versions available for org.codehaus.plexus:plexus-archiver:jar:[1.2,3.0)".

I changed the pom configuration for gae-plugin :

<plugin>
    <groupId>net.kindleit</groupId>
    <artifactId>maven-gae-plugin</artifactId>
    <version>0.9.4</version>
    <dependencies>
        <dependency>
            <groupId>org.codehaus.plexus</groupId>
            <artifactId>plexus-archiver</artifactId>
            <version>2.1.2</version>
        </dependency>
    </dependencies>
</plugin>
