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 ...
