In the documentation of declarative pipelines, It is mentionned that you can't use when in the post block. when is allowed only inside a stage directive. So what you can do is test the conditions using an if in a script:

post {
success {
  script {
    if (${env.BRANCH_NAME} == 'master')
        currentBuild.result = 'SUCCESS'
  }
 }
// failure block
}
