Question

After a simple apt-get update on ubuntu 10.11, I lost the svn polling possibility. None of my projects, that could poll svn, can anymore.
The plugin Update center shows an update is available for this plugin ( 1.34 -> 1.37 ) but update does not work, wether with web interface or cli.
Jenkins logs show a whole bunch of errors relating the subversion plugin

ATTENTION: Caught exception evaluating: it.isTagged(). Reason: java.lang.NullPointerException

etc … etc …

I removed by hand :

drwxr-xr-x 4 jenkins nogroup     4096 2012-01-25 16:33 subversion
-rw-r--r-- 1 jenkins nogroup  2105983 2012-01-24 18:34 subversion.bak
-rw-r--r-- 1 jenkins nogroup  2105983 2012-01-24 18:34 subversion.hpi
-rw-r--r-- 1 jenkins nogroup        0 2012-01-25 16:31 subversion.hpi.pinned
-rw-r--r-- 1 jenkins nogroup  2103308 2012-01-25 16:31 subversion.jpi

but the plugin keeps being listed in the update area.

Question : what is the proper procedure to remove EVERY and ALL references to this plugin, to make a very clean reinstall ?
thanks

it seems to be common problem

try these steps

• Downgrade jenkins, restart

• Disable subversion plugin, restart

• Upgrade jenkins, restart

• Enable subversion plugin, restart

• Edit each build configuration, enable subversion, save.
