This is a simple plugin that changes the next build number Hudson will use for a job.
This functionality is useful if you are using the Hudson build number as part of a version string, but you do a build outside of Hudson and you want Hudson to skip that number for the next build to avoid duplicate version numbers.
Hudson requires that build numbers are always increasing. When you click on the link installed by this plugin, a text field will be shown that contains the next build number Hudson will use. You can change this number to be anything larger than this value. Changing this to a smaller number will do nothing.
