[jira] Commented: (ARCHETYPE-159) mvn archetype:generate is failing to download needed archetype artifacts

["Olivier Martin (JIRA)" <ji...@codehaus.org>]

    [ http://jira.codehaus.org/browse/ARCHETYPE-159?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=130987#action_130987 ] 

Olivier Martin commented on ARCHETYPE-159:
------------------------------------------

Same error here, there is an incompatibility between the archetype plugin and Maven 2.0.9.

I can reproduce it with any of the default catalog and with our own catalog.
The only workaround is to have a local version of the archetype, it's not downloaded from the server.

{code}
Downloading: http://static.appfuse.org/releases/org/appfuse/archetypes/appfuse-basic-jsf/2.0/appfuse-basic-jsf-2.0.jar
org.apache.maven.archetype.downloader.DownloadException: Error downloading.
        at org.apache.maven.archetype.downloader.DefaultDownloader.download(DefaultDownloader.java:58)
        at org.apache.maven.archetype.common.DefaultArchetypeArtifactManager.exists(DefaultArchetypeArtifactManager.java:310)
        at org.apache.maven.archetype.ui.DefaultArchetypeGenerationConfigurator.configureArchetype(DefaultArchetypeGenerationConfigurator.java:103)
{code}


For me this is a blocker.

> The same error also happens with an archetype artifact ID of "maven-archetype-webapp" (and probably all the others as well).
> However, if I issue the same command but using archetype:create instead of :generate, not only will the archetype artifact correctly download (and the command work successfully), subsequent usages of archetype:generate with that same archetype artifact will also correctly run.
> So I think the problem is that mvn archetype:generate needs to download archetype artifacts just like mvn archetype:create does.
