copied!<p>First of all, thanks for answering :)</p> <p>Today I'm trying to get a better understanding of how archetypes works looking at the tutorial on maven <a href="http://maven.apache.org/guides/mini/guide-creating-archetypes.html" rel="nofollow noreferrer">here</a>, althought is still very disapointing.</p> <p>My problem is that I am having a build failure in maven when I try to do the mvn archetype:generate instruction. This is, as simple as possible, my problem. The build problem says that 'The defined artifact is not an archetype'. </p> <p>I have tried the decreapted instruction archetype:create and the error is more or less the same but it adds that 'Embedded error: The META-INF/maven/archetype.xml descriptor cannot be found.' In my archetype there is an archetype.xml so it seems that the decreapted instruction is decreapted for a good reason.</p> <p>My total instruction is at follows</p> <pre><code>mvn archetype:generate -DgroupId=my_groupid -DartifactId=my_artifactid -Dversion=1.0 -DarchetypeGroupId=archetype-foo-lib -DarchetypeArtifactId=my.archetype.foo -DarchetypeVersion=1.0 -DarchetypeRepository=C:/.m2/repository -Dbasedir=C:/.m2/repository/archetype-foo-lib -B -DinteractiveMode=false </code></pre> <p>In basedir I have the pom.xml and the dom4j.jar and the repository is up (in a little tomcat server). Also, the archetype is installed and the archetypegroupid, archetypeartifacid and archetypeversion are the same as the one in the src\main\resources\archetype-resources folder. I also tried to change the slashes to '\' in the basedir (just in case) with no better results.</p> <p>As I am now trying to do it directly in maven console you can forget about the webapp project and all that stuff. I can hopefully make it work there once it starts working in the console.</p> <p>Alas! Also I have the stacktrace (as I have also done this with -e parameter)</p> <pre><code>+ Error stacktraces are turned on. [INFO] Scanning for projects...

I am know investigating why it seems to not be an archetype, and it seems that mvn archetype:generate -DarchetypeCatalog=local has 0 archetypes. So it appears that it's not installed. I have done the mvn install and the mvn archetype:crawl but it doesn't work. Any ideas why it doesn't let me install my own archetypes? Thanks again :)</p> <p>Edit Again: Problem with local archetypes resolved, I had to move the archetype-catalog.xml from ~/.m2/repository/ to ~/.m2/ and then just like that Maven found my local archetypes. Strange off all, it still gives me the same error. I have also changed my archetype repository and base dir.</p> <p>Last Edit (I hope so!): well, I finally found the error. It's so stupid I feel my self ashemed to write t down (it's been three days by know becouse of this). My archetypeArtifactId and my archetypeGroupId where exchanged (I mean, one was the other). Once I started passing the corrtect parameters (defined in archetype-catalog.xml that, although, I still had to move to the correct place) it started to do wonders. Thanks too all peoplo who read or wrote :)</p>
