(Maven issue) Unknown packaging: hpi

[jonjendev]

I am trying to start developing plug-ins for Jenkins with Mac OSX.

FIrst, when I run 'mvn hpi:create', it takes a reeaally long time to
download all the files, up to several minutes per file. And it's a lot
of files. Total time is 4-5 hours! Why is it so slow?

Then, when I run 'mvn package' I get this error:

Why does maven not know about hpi?

This is my pom.xml:

www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://

I have changed the <version> of Jenkins to the version on my computer.
How can I resolve this error?

[domi]

see here: https://wiki.jenkins-ci.org/display/JENKINS/Plugin+tutorial
you probably did not add this to your settings.xml:
<settings>
<pluginGroups>
<pluginGroup>org.jenkins-ci.tools</pluginGroup>
</pluginGroups>
….

Hello,

it looks like maven fails at opening the jar containing the plugin. It is probably corrupted on your machine. You should try to delete org\jenkins-ci\tools\maven-hpi-plugin from your local repository and try again.

Before he goes deleting it, he might want to have a peek at it with e.g. less

I suspect it might be HTML, probably explaining why that file was not
downloaded correctly ;-)
