7. Now you can use in your job the variable created.

For the example provided you only have to add -t $TOOLCHAIN in your Goal of your maven job

Note: You need to have one or several JDK installed on the agent and you have to hardcode their paths in the toolchain (You could have some problem using the path of JDKs installed with the default JDK Installer or with the Custom tools installer)

Option 2: Placing the toolchain under $HOME/.m2/toolchain.xml

Same as Option 1 for steps from 1 to 5 and then:

6. Go to your Maven project job and in the “Build Environment” section, click on “Provided configuration files”, select the toolchain file created and choose a Target a fill it with $HOME/.m2/toolchain.xml (its default location)
