   For example, <h1>Hello world! ${artifactId}</h1> in ${project-path}/target/generated-sources/archetype/src/main/resources/archetype-resources/src/main/webapp/WEB-INF/views/home.jsp
4. Create jar.
   Please note that the SNAPSHOT cann’t be published into release repository.

Create New Project from Published Archetype

Create from http://localhost:8081/nexus/content/repositories/releases/ as other public archetype.
When I use myApp as Artifact Id, the home.jsp is rendered ${artifactId} as myApp.

Done!!
