Subject RE: Jenkins builds take hours?
Date Wed, 24 Oct 2012 01:33:38 GMT
Thanks Steve and Britt.  These are great suggestions.
The below have been created now:
will check for svn for changes and will run compile test
(auto archiving disabled now)
runs @daily

Let's see how that works out.  Keep in mind that Jenkins distributes it's load across shared
hardware so if it's a new machine, it may take longer for a fresh checkout.

FYI: if you need admin access to create/edit jobs, any one of the chairs should be able to
run the command to grant you access to Jenkins (if not, open an infra jira): hudson-jobadmin --add=<Apache username>

Note that `mvn package` isn't the problem - the entire `mvn install` only takes 15 minutes
on our Jenkins. The delay comes from Jenkins archiving stuff after the build.

But I agree that it makes a lot of sense to just run `mvn test` on every commit, and `mvn
package` only once a day. And if we're going to let Jenkins archive anything, we could restrict
it to the results of that once-daily `mvn package`.
