Creating a Maven plugin Project using an archetype

Maven Archetypes are discussed in detail here.

1. From the command prompt, change directory to the location where you want to setup the maven plugin project.
2. Run the following command to set up a skeleton Maven Plugin project.

   
    mvn archetype:create -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-mojo \
        -DarchetypeVersion=1.0-SNAPSHOT -DgroupId=org.codehaus.plexus -DartifactId=plexus-website-monitor-plugin
   

The maven-archetype-mojo sets up a skeleton Maven plugin project 'plexus-website-monitor-plugin' for us with reasonable defaults.

Updating pom.xml dependencies

1. Locate pom.xml under the 'plexus-website-monitor-plugin' folder.
2. Edit it and add a dependency to the plexus-website-monitor-component that we have developed in earlier chapters.

   The pom.xml should look like this now:

   <?xml version="1.0"?>
   <project>
     <modelVersion>4.0.0</modelVersion>
     <groupId>org.codehaus.plexus</groupId>
     <artifactId>plexus-website-monitor-plugin</artifactId>
     <packaging>maven-plugin</packaging>
     <name>Maven Mojo Archetype</name>
     <version>1.0-SNAPSHOT</version>
     <url>http://maven.apache.org</url>
     <dependencies>
       <dependency>
         <groupId>org.apache.maven</groupId>
         <artifactId>maven-plugin-api</artifactId>
         <version>2.0</version>
       </dependency>
       <dependency>
         <groupId>junit</groupId>
         <artifactId>junit</artifactId>
         <version>3.8.1</version>
         <scope>test</scope>
       </dependency>
       <dependency>
         <groupId>org.codehaus.plexus</groupId>
         <artifactId>plexus-website-monitor-component</artifactId>
         <version>1.0-SNAPSHOT</version>
       </dependency>
     </dependencies>
   </project>

Setting up an Eclipse project

Note that this step assumes that we have Plexus Website Monitor Component available in our local repository or downloadable from a remote repository.

1. Run the following command to generate Eclipse project and set up library path to dependencies.

    mvn eclipse:eclipse

2. From the Eclipse workbench, use 'File > Import > Existing projects into workspace' to import the created maven plugin project.

   The website monitor plugin should now be set up as a project under Eclipse.
