I'm using a single Repository URL with parameterized value: ${SVN_URL}/application, where SVN_URL is defined as a node level parameter. in that case SCM polling keeps running and chackout the entire workspace although there are no changes on SVN.

scm-polling.log:
Workspace doesn't contain ${SVN_URL}/application. Need a new build.
Done. Took 0 ms
Changes found

When using a clear text Repository URL all works fine.
