Error: no workspace

There's no workspace for this project. Possible reasons are:

1. The project was renamed recently and no build was done under the new name.
2. The slave this project has run on for the last time was removed.
3. The workspace directory (/home/tomcat/.jenkins/workspace/org.bouncycastle.openpgp.wot) is removed outside Jenkins.
4. The workspace was wiped out and no build has been done since then.

Run a build to have Jenkins create a workspace.
