The configurations are stored by your backup magic:

https://github.com/freebsd/jenkins-config/tree/master/jobs/FreeBSD_HEAD-scan-build

There are some tricky points:

- "Multiple SCMs" plugin is used, for check out both scan-build scripts
  and source being checked
- scan-build is build from LLVM & Clang trunk, which are also checked out by
  multiple SCMs plugin and built when job triggered.  This is designed
  by uqs@ at the beginning because we want to use the latest tool to
  eliminate false results.

The build process is straightforward, just copying necessary files and
executing scan-build:

https://github.com/freebsd/jenkins-config/blob/50f1336a04b039852b73780314c3967e5d6f9b07/jobs/FreeBSD_HEAD-scan-build/config.xml#L85-L107

The scripts are stored here, they are originally developed by uqs at .

https://github.com/freebsd/freebsd-ci/tree/master/scan-build

Perhaps we can split this to another repository in the future.

This is interesting, I also want the clang-scan build plugin can support
scan-build from command-line.  I hope this can help to collect and
publish the results.  The way we publish scan-build results is a bit
dirty.
