Unable to set maven in groovy script

Question

I am using groovy script in jenkins pipeline job and I need maven to execute my stage.

I do not have control of .profile as it is running on slave. I need to set the Maven in my groovy script so that I can run man clean compile .

maven is located at /opt/runtime/apache-maven-3.3.3/bin/mvn.

I am very new to groovy and want to know how to use this.

You can do something like this:

// Maven location
def mvnHome = tool name: 'maven 3_3_9', type: 'hudson.tasks.Maven$MavenInstallation'
env.MAVEN_HOME = mvnHome

// Begin Compile
stage concurrency: 1, name: 'compile'
sh '''${MAVEN_HOME}/bin/mvn clean compile'''

Please note that the tool name comes from the Maven configuration you have defined in the Global Tool Configuration page.
