Jenkinsfile variable used in two separate stages

I have a pipeline job that uses two separate nodes (one for build, one for test), and I'd like to share a variable between two of these blocks of code in my Jenkinsfile. I assume it's possible, but I'm very new to groovy and the Jenkinsfile concept. Here is the relevant code so far:

node('build') {
    stage('Checkout') {
        checkout scm
    }
    stage('Build') {
        bat(script: 'build')
        def rev = readFile('result')
    }
}

node('test') {
    stage('Test') {
            def SDK_VERSION = "5.0.0001.${rev}"
            bat "test.cmd ${env.BUILD_URL} ${SDK_VERSION}"
            archiveArtifacts artifacts: 'artifacts/**/*.xml'
            junit 'artifacts/**/*.xml'
       }
}

I want to assign the "rev" variable in the build stage, but then concatenate it to the SDK_VERSION variable in the Test stage. My error is: 

groovy.lang.MissingPropertyException: No such property: rev for class: groovy.lang.Binding

In a declarative pipeline, @mkobit's answer won't work. You can, however, switchinto script mode explicitly and use its scoping, e.g. like so:

...
steps {
   script {
       def foo = sh script: "computeFoo", returnStdout: true

       node('name') {
           script {
               someStep()
           }
       }
    }
}
...

Just define the variable before your node block:

def rev = ''
node('build') {
  stage('Checkout') {
    checkout scm
  }
  stage('Build') {
    bat(script: 'build')
    rev = readFile('result')
  }
}
