グルーヴィーな変数を印刷する方法は？

Jenkinsパイプライン内に次のコードがあります。

stage ('Question') {
    try {
        timeout(time: 1, unit: 'MINUTES') {
            userInput = input message: 'Choose server to publish to:', ok: '', parameters: [
                [$class: 'hudson.model.ChoiceParameterDefinition', choices: 'pc-ensureint\nother-server', description: 'Choose server to publish to:', name: 'server']
        ] 
      }
    } catch (err) {
        userInput = [server: 'pc-ensureint'] // if an error is caught set this value
    }
}

node () {
    println ${server}
}

「ChoiceParameterDefinition」で設定されている「server」変数の問題をトラブルシューティングしようとしています。

ビルドを実行すると、次のエラーが表示されます。

私の知る限り、「サーバー」はグルーヴィーな変数なので、$ {}を使用してアクセスできるはずです。

だから私は試しました：

echo ${server}
print ${server}
println ${server}
println "${server}"

しかし、私が何をしようとしても、このエラーが発生し続けます。

私が間違っていることを知っていますか？

次のコードは私のために働いた：

echo userInput

yorammi

文字列の外にいるときは${varName}を使用しないでください。varNameを使用するだけです。文字列の中では、このように使用します。 echo "this is a string ${someVariable}";。実際、一般的なJava式を${...}内に配置できます。 echo "this is a string ${func(arg1, arg2)}。
