In the technique below, the echo lines are run on the remote (slave node). The “Inject environment variables” step works on the slave node and reads any files it needs from there, not the server. Also, this technique was built to allow one shell step to calculate the values of environment variables and inject them into later steps. Given your specific case, you don’t have to get this involved.
The environment variables in your case below don’t appear to depend on anything the job does. These variables look like properties of the machine you’re running on. While the envInject technique would still work, you could set the environment variables either at the build environment section of the job or in the node configuration. In either case, you’ll have to specify ACE as “/opt/play/apps/default-ace/ACE”; “$APPS/default-ace/ACE” only makes sense within a shell. There’s a good argument to be had for inserting these variables in the slave node itself, as they describe information specific to that host rather than specific to any job. If you do set the environment variable at the slave level, make sure to reboot the slave by selecting Disconnect on it (slaves should restart themselves)—until the slave process reboots, it will have the old values for environment variables. --Rob (Same Rob, different job) From: jenkinsci-users@googlegroups.com [mailto:jenkinsci-users@googlegroups.com] On Behalf Of Adrian Paraschiv Sent: Friday, January 16, 2015 6:43 AM To: jenkinsci-users@googlegroups.com Cc: rmandevi...@litle.com Subject: Re: Variable from shell script to Jenkins job Hello Rob, I have a couple of questions: 1. The line "echo “varID = $varID” > export_props.properties" is run on the jenkins server or on the remote ? 2. If I need something like this on the remote server for a script that jenkins runs: .......... export APPS="/opt/play/apps" export ACE="$APPS/default-ace/ACE" .......... What would be the best method to use: 1. Add build step (before Execute shell ) "Inject enviromnet variables" and at the "Properties Content" I add the above...or 2. At "Build Environment" check "Inject environment variables to the build process" and add the above at "Properties Content" Thanks On Thursday, January 23, 2014 at 5:55:55 PM UTC+2, Mandeville, Rob wrote: We’ve got a technique for this at our shop. It requires the envInject plugin. You write a line such as: echo “varID = $varID” > export_props.properties In the step after the shell step, create an “Inject environment variables” step that reads from export_props.properties. Now, the contents of export_props.properties is injected into the job itself, and will be injected into shell steps as environment variables. --Rob From: jenkins...@googlegroups.com<javascript:> [mailto:jenkins...@googlegroups.com<javascript:>] On Behalf Of Naumenko, Roman Sent: Thursday, January 23, 2014 10:50 AM To: jenkins...@googlegroups.com<javascript:> Subject: Variable from shell script to Jenkins job Jenkins experts, Does anybody remember how to pass variable from shell execution inside the job to Jenkins itself? Say there is pre-step: varID=(grep something ${WORKSPACE}/pom.xml | cut something else) Is it possible to use $varID in further non-shell steps in the job? --Roman _______________________________________________________________________ This email is intended only for the use of the individual(s) to whom it is addressed and may be privileged and confidential.
