using settings files in environment

[Bill C]

  In a declarative pipeline, is it possible to define a variable for a settings file in the environment section?

Currently many of my stages have for following form

steps {
   configFileProvider([configFile(fileId:'M3',variable:'MAVEN_SETTINGS')]) {
      sh 'mvn -s $MAVEN_SETTINGS ...'
   }
}

 Since it appears in basically every stage I think it really clutters up the pipeline. I'd like to do something like this

environment {
   MAVEN_SETTINGS = configFile('M3')
}

...

steps {
   sh 'mvn -s $MAVEN_SETTINGS ...'
}

I've been combing through the docs but have not found anything. Does anyone know if something like this is possible?

 Thanks
