View URLTrigger on the plugin site for more information.
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 an 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)
Note: The plug-in uses only persistence in memory. There is no impact on the Jenkins infrastructure (no new files created).
This plugin provides a polling typology among the XTrigger Plugin.
Some Use cases
* This plugin 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).
* This plugin is useful to know if a stage of a pipeline (for a continuous testing, a continous delivery or a continuous deployment) has to be executed.
Only http(s) and ftp URLs are supported. For non-http protocols, consider other XTrigger plugins such as the FSTrigger Plugin
Declarative Pipeline Syntax
Comparison with similar plugins
This plugin supports all URL Change Trigger features and it includes all the fixes of the current URL Change Trigger issues.
And unlike the URL Change Trigger, URLTrigger plug-in is also able to check the content nature (TEXT, XML, JSON) of a file.
Additionally the plugin can be extended (in the same plugin or by an other plugin) to check other content type.
Bugfix for the 'inspect content' checkbox being incorrectly set automatically.
Pipeline compatibility. As well as now supporting pipeline jobs, declarative syntax for triggers is supported.
Bugfix: Triggers configured to check ETag values no longer build immediately on Jenkins startup
