Jenkins: SCM triggering constant builds despite no change

Question

We have a problem where despite no code changes SCM is triggering a build. SCM polls for changes every 15 minutes and should only trigger a build if changes are found.

Answer 1

Be carefull with svn redirections, in my case i had the same case Jenkins could not detect if svn has no changes and allways was triggering.

The problem was that in my jenkins svn configuration had this url:

https://xxxx.yyy.es:443/svn/myproject/trunk and its redirect to

http://xxxx.yyy.es:8008/svn/myproject/trunk (i dont know why)

Jenkins had to be configured with the last URL in order to detect the svn changes properly.

This is my issue Resolved.
