Hi,
I'm trying to use the maven extension capability in my plugin. My test
is based on the Plexus tutorial. I have made one extra operation by
adding an API project where I have put the
org.codehaus.plexus.tutorial.WebsiteMonitor interface.
I have a API project (plexus-website-monitor-api) that declares a ROLE
within an Interface: WebsiteMonitor.
I have a project (plexus-website-monitor-component) with a default
implementation of my interface: DefaultWebsiteMonitor implements
WebsiteMonitor.
I have a plugin project (plexus-website-monitor-plugin) that uses this
component interface as an attribute of MonitorMojo.
Everything works fine if I declare in the plugin's 'pom.xml' a
dependency on the plexus-website-monitor-component artifact (the
implementation) :
<project>
...
<dependencies>
...
<dependency>
<groupId>org.codehaus.plexus</groupId>
<artifactId>plexus-website-monitor-component</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
</dependencies>
...
</project>
BUT if in my plugin pom.xml I declare a dependency on the API as follow:
<project>
...
<dependencies>
...
<dependency>
<groupId>org.codehaus.plexus</groupId>
<artifactId>plexus-website-monitor-api</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
</dependencies>
...
</project>
and in the project that use the plugin I add the extensions tag as
follow:
<project>
<build>
<plugins>
...
</plugins>
<extensions>
<extension>
<groupId>org.codehaus.plexus</groupId>
<artifactId>plexus-website-monitor-component</artifactId>
<version>1.0-SNAPSHOT</version>
</extension>
</extensions>
</build>
</project>
I get an error on the command line :
[INFO] Internal error in the plugin manager executing goal
'org.codehaus.plexus:plexus-monitor2-plugin:1.0-SNAPSHOT:monitor':
Unable to find the mojo
'org.codehaus.plexus:plexus-monitor2-plugin:1.0-SNAPSHOT:monitor' in the
plugin 'org.codehaus.plexus:plexus-monitor2-plugin' Component descriptor
cannot be found in the component repository:
org.codehaus.plexus.tutorial.WebsiteMonitor.
Does it mean that extensions and dependencies are not loaded by the in a
same way?
How can I resolve It, I suppose it is the same execution context for my
plugin than a Wagon specific implementation but I do not known why it
does not work for me... :-(
Please Help ...
Thanks,
Romain
