Environment variable in Jenkins Pipeline

Question

Is there any environment variable available for getting the Jenkins Pipeline Title   I know we can use  JOB NAME to get title for a freestyle job   but is there anything that can be used for getting Pipeline name

You can access the same environment variables from groovy using the same names (e.g. JOB_NAME or env.JOB_NAME).

From the documentation:

Environment variables are accessible from Groovy code as env.VARNAME or simply as VARNAME. You can write to such properties as well (only using the env. prefix):
env.MYTOOL_VERSION = '1.33'
node {
  sh '/usr/local/mytool-$MYTOOL_VERSION/bin/start'
}
These definitions will also be available via the REST API during the build or after its completion, and from upstream Pipeline builds using the build step.

To avoid problems of side effects after changing env  especially using multiple nodes  it is better to set a temporary context   One safe way to alter the environment is    withEnv   MYTOOL HOME  usr local mytool          sh   MYTOOL HOME bin start       This approach does not poison the env after the command execution
