As discussed with teilo, we should use "File.getCanonicalPath()" instead of "File.getAbsolutePath()" to prevent mismatches between the path seen by the Maven Event Spy and the path reported by the Jenkins master.

We have faced such mismatch in https://github.com/jenkinsci/pipeline-maven-plugin/commit/33a8425c88d8d2f18c03d4d62a8b957064370975
