This will NOT be passed to your script. # CHECKING ANT TASK RESULTS WITHIN ANT SCRIPT ############################################# # If you want to run some <exec> and then check the results of that execution, you can do so in the ant script that calls RSSFeedWatcherTask. # The following properties will be set after you run the task: # feedWatchAction.Result.0 - The result returned from the <exec> task; if set, something bad happened # feedWatchAction.Error.0 - Details about the error that occurred, if set, something bad happened # feedWatchAction.Output.0 - Console output from your <exec>, if any; # this will depend on what you run in response to a feed change, and if that process produces console output # feedWatchAction.OldValue.0 - The original value of the node you asked for, from the previous cached version of the feed # feedWatchAction.NewValue.0 - The changed value of the node you asked for, from the latest version of the feed; # if you asked for changes to the test status for performance tests, this could be "PASS"; # if you asked for any changes to the feed, this will be the XML datestamp of the last update, eg: 2006-05-04T12:14:33Z # # If you are watching for more than one condition, you can check for feedWatchAction.Result.0, feedWatchAction.Result.1, feedWatchAction.Result.2, etc. # RUNNING NO EXTERNAL <exec> ############################################# # If you only want to check for changes to the feed and handle the response yourself within Ant instead of an <exec>, # simply pass in the executable as "null" to prevent any shell execution from occurring. For example: # feedWatchActions=//*[name() = 'entry'][1]/*[name() = 'updated']/text(); null; null # If the node is found and the feed has been changed, the property feedWatchAction.NewValue.0 # (and/or feedWatchAction.NewValue.1, feedWatchAction.NewValue.2, etc.) will be set to the new changed value. # XPATH EXAMPLES - SAMPLE NODES TO WATCH FOR CHANGES #################################################### # 1. to watch for ANY change in the feed, check the <feed>'s <updated> node (and respond with an email, passing -debug 1 to the mail script) # feedWatchActions=/*[name() = 'feed']/*[name() = 'updated']/text(); ../scripts_rss/sendEmailAlert.sh; -debug 1 # 2. to watch for ANY changes in the current build, check the first <entry>'s <updated> node (and respond with an email, no commandline flags) # feedWatchActions=//*[name() = 'entry'][1]/*[name() = 'updated']/text(); ../scripts_rss/sendEmailAlert.sh; null # 3a. to watch for coordinated status changes, check the first <entry>'s <build> node's coordinated="" attribute (and respond using some custom Ant script) # feedWatchActions=//*[name() = 'entry'][1]/*/*/*[name() = 'coordinated']/@status; null; null # 3b. to watch for jar signing status changes, check the first <entry>'s <build> node's jars="" attribute (and respond using some custom Ant script) # feedWatchActions=//*[name() = 'entry'][1]/*/*[name() = 'build']/@jars; null; null # 3c. to watch for changes in the current build's performance test results on linux-gtk (and respond using some custom Ant script) # feedWatchActions=//*[name() = 'entry'][1]/*/*/*/*[@type = 'performance']/*[name() = 'result'][@os = 'linux'][@ws = 'gtk']/text(); null; null
