Install the Kundo Hudson Plugin, you should be able to do this through the management interface, if not, upload the kundo.hpi manually and restart Hudson.
If you only have one Kundo installation on your system and already have the KUNDO_HOME environment variable set, this installation will be picked up automatically. You can however add additional Kundo installations by selecting Manage Hudson and then selecting Configure System from the Hudson interface.
Scroll down the page, if the plugin was successfully installed you should see a section entitled Kundo. Click the Add button to add an extra installation:
Give your installation a name you will recognise, could be a version, in the name field.
That is it for adding additional Kundo installations. Now you will want to configure a job.
Click New Job then select Build a free-style software project, give your job a name and click OK.
Enter all the appropriate source code management and job information and then the select Add build step button. From the drop down list that appears select Invoke Kundo job.
Now you can select the Kundo installation you wish to use, and simply add the phases you want to call Kundo with in the Phases field. If you want to specify properties to modify Kundo behaviour, and you probably do, click the Advanced button:
Now you can add properties in the Properties field that has just appeared. Add one property per line, if you need to expand the field, click the arrow on the right hand side and you can carry on adding properties to your heart's content.
