How do i pass a build number to a downstream job for jobs that are part of a Build Pipeline

[Eric Wood]

I use the build pipeline to manage a series of related jobs (downstream).  I want to be able to pass the build number from the upstream job to be used in the downstream jobs as the build number there.  How is this best accomplished.

Thanks, Eric

Hi,

I usually  add a "Predefined parameter" something like MYBUILD_NUMBER=${BUILD_NUMBER}  and use that environment variable (Parameter) in the next build step.....

Chris:

Thanks for the reply. Not sure i fully understood the steps. Can you elaborate? Where do i set a Predefined parameter and are you saying that once the variable is predefined I can merely reference the variable using the ${MYBUILD_NUMBER} in the downstream job?

Some of our jobs use the following script in a build step to set the build number of the downstream jobs:

 

echo **** Keep build numbers in pipeline consistent ******

"C:\Program Files (x86)\Curl\curl.exe" -d "nextBuildNumber=%BUILD_NUMBER%" http://user:password@localhost:8080/job/DOWNSTREAM_JOB1/nextbuildnumber/submit

"C:\Program Files (x86)\Curl\curl.exe" -d "nextBuildNumber=%BUILD_NUMBER%" http://user:password@localhost:8080/job/DOWNSTREAM_JOB2/nextbuildnumber/submit

 

 

This uses the nextbuildnumber plugin.

I use the ParameterizedTriggerPlugin to pass various properties, including build name/number, to downstream jobs.  In the upstream job, I have a build step to write the properties to a properties file in the workspace.  Then, using the plugin’s “Trigger parameterized build on other projects” task, I specify the downstream project and specify the properties file in the “Parameters from properties file” field.

 

Then, in the downstream job configuration, select “This build is parameterized” and create a “string parameter” for each of the desired properties from the properties file you created in the upstream job.
