詳細：

• Javaバージョン64ビット、1.8.0_91です。
• Eclipse Neon 4.6;
• Linux Debian 64ビット;
• Oracleの仮想ボックス4.3
• ロボットFramework 3.0の（Pythonの2.7.9）

これは、プラグインの問題であることを縫い目が、私は誰かが回避策を発見したかどうかを知りたいと思います。 https://github.com/NitorCreations/RobotFramework-EclipseIDE/issues/72

Answer 1

EclipseでRobotframework IDEをセットアップしようとしているときに、Nokiaが開発したREDを試してみたのかと思いました。

私の考えでは、より多くの機能（行ごとにデバッグ）、構文のハイライティング、コード補完&カスタム実行パラメータがあり、まだアクティブな開発中です。 NitorCreationさんは2015年10月以降にリポジトリを更新していません。
