How to invoke Inject environment variables to the build process plugin in jenkinsFIle jenkins 2.x with pipeline

Question

I'm trying to migrate my project from jenkins 1 to jenkins 2.x using pipeline as code or Jenkinsfile.
But I don't see any option in snippet generator to generate environment injector plugin into a script in Jenkinsfile.

Anyone can help?

Answer 1

I'm assuming that you want to read properties from a specific file and inject them as environment variables?

If so, this is a solution:

• Create the file that will contain the environment properties

  • You create some properties file called project.properties with following content:

    PROJECT_VERSION='1.4.34'

Then, on your pipeline code, you've to add the following code in order to be able to read the file and inject read variables as environment variables:

node { load "${WORKSPACE}\\project.properties" // assuming that props file is in Jenkins Job's workspace echo "PROJECT VERSION: ${PROJECT_VERSION}" }

• First line read and inject variable PROJECT_VERSION as environment variable
• Second line is just to print read variable to make sure that everything worked seamlessly

Result:

Wanted to just comment on your question, but my lack of reputation is hindering me.

The list of supported steps is here: https://jenkins.io/doc/pipeline/steps/

In general, you can use other plugins by using their Java style invocation.

i.e.

step([$class: 'classname', parametername: 'value'])
