it looks you're getting an issue finding your archetype jar in your local repository, and the message is misleading: I'd love to improve it
can you share the stacktrace of your failed execution (add -e to your command line)? You can in parallel look at simple archetypes source code, to see the happy path, like https://maven.apache.org/archetypes/maven-archetype-simple/ and its source https://github.com/apache/maven-archetypes/tree/master/maven-archetype-simple look at its pom.xml (that has maven-archetype packaging): I hope your own archetype project uses this packaging), do "mvn install" to install 1.5-SNAPSHOT, and "mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-simple -DarchetypeVersion=1.5-SNAPSHOT" to generate a project from it Regards, Hervé On 2023/10/06 16:11:36 David Karr wrote: > Thanks for the responses.
