Grails Maven Plugin

This NoClassDefFoundError (see attached screen shot) is thrown straight out of the box with version 1.1beta1 (as of 12/15/08). Steps to reproduce:

• Create new project using grails-maven-archetype
• CD into new project directory
• Do 'mvn initialize'
• Do 'mvn grails:create-domain-class' and enter Foo as the class name
• Do 'mvn grails:generate-all' for the Foo class
• Do 'mvn clean package' (not really necessary step)
• Do 'mvn grails:run-app' and navigate to your app
• In the Welcome screen, click on 'FooController' link
• Following NoClassDefFoundError error is thrown indicating the classpath is missing some core JSTL dependencies:

I proceeded to add the following dependency in the project pom:

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>

Re-ran the app and the error now changes to:

Error 500: JSP support not configured
Servlet: jsp
URI: /grails-test/WEB-INF/grails-app/views/foo/list.jsp

Seems that some base dependencies and configs might still missing from the archetype.

Let me know if I left out any needed information. I'll be happy to keep testing this.

There are actually two problems here:

1. The "generate-all" command is not creating the views.
2. Both JSTL and Jetty's JSP support are missing

To fix the first, I need to change one of the Grails scripts. For the second, I will add JSTL to the archetype pom.xml and Jetty's JSP support as a dependency of "grails-scripts" artifacts.

Deployed new Grails artifacts and archetype.

Confirmed. Cleared my local maven repository and downloaded the latest archetype. The JSTL dependencies are now declared and 'generate-all' creates the views.
