create grails project from Maven archetype

Question

When I try to create a Mavenized Grails 1.3.6 project using the archetype:

mvn archetype:generate -DarchetypeGroupId=org.grails 
-DarchetypeArtifactId=grails-maven-archetype -DarchetypeVersion=1.3.6 
-DgroupId=example -DartifactId=my-app 
-DarchetypeRepository=http://repo1.maven.org/maven2

I get the error

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:2.0:generate (default-cli) on project standalone-pom: The desired archetype does not exist (org.grails:grails-maven-archetype:1.3.6)

I've checked the repository and version 1.3.6 does exist. Moreover, if I replace version 1.3.6 in the command above with 1.3.2, it works.

Answer 1

Run mvn archetype:generate (interactive mode) and select option 286

286: remote -> grails-maven-archetype (Maven archetype for Grails projects.)

In general, I've had way more troubles than solutions with maven archetypes :S.

Answer 2

I don't know what's going on with your particular configuration, but I ran the exact command you listed there and it built successfully. Since I'm guessing this is related to your previous question about how to specify dependencies, I suspect that you care more about the contents of the pom file than actually figuring out what's going on with the archetype, I'll post the pom.xml file that the archetype generated for me.

New maven archetype for grails 2 will be available soon. See MAVEN-162
