URLTrigger

ID: urltrigger

UrlTrigger Plugin

URLTrigger plug-in makes it possible to monitor changes of the response got from an URL invocation.

Features

Jenkins can be configured to poll URL changes.
The plug-in makes it possible to check the last modification date response and the response content of a URL invocation.
For the response content, you can check:

  • a simple response content (the content nature is not interpreted; a MD5 is used)
  • a TXT response content (the returned values from the evaluation of regular expressions are checked)
  • an XML response content (the returned values from the evaluation of XPath expressions are checked)
  • a JSON response content (the returned values from the evaluation of JSONPath expressions are checked)

Some Use cases

  • Enables users to check if new artifacts (such as binaries) have been deployed in a repository (managed for example by a repository manager such as Sonatype Nexus, JFrog Artifactory, Apache Archiva and so on).
  • Know if a stage of a pipeline (for a continuous testing, a continous delivery or a continuous deployment) has to be executed.

Known Limitations

Only http(s) and ftp URLs are supported. For non-http protocols, consider other XTrigger plugins such as the FSTrigger Plugin
