EclipseはオープンJSPエディタ

Question

のEclipseプラットフォームはできません - バージョン：3.8.1、Ubuntuの16.04

の下で、私は一般的なEclipseプロジェクトで開いたファイルのWebアプリケーション・グループを持っています。ここで私はjavaとjspファイルが動作するようになっています。

マーケットプレイスをダウンロードしてプラグインを提案したので、Eclipse Web Developer Tools、Eclipse Plug-in Development Environment、Eclipse Java Web Developer Tools、 Eclipse Java Development Tools）ので、私はJava EEパースペクティブに切り替えてJSPエディタを起動できます。

このようにして、.jspファイルを開こうとすると、以下のペーストで他のエラーが発生します。

私は、Eclipseが不正なJavaバージョンを使用していると思われますが、それがどのバージョンであるかを確認する方法を見つけることができません。私はそれが/ usr/lib/eclipseのeclipse.iniファイルにあるべきだと読んでいますが、そのファイルには何も似ていない（それは-vmという行があるはずです。

私はアイデアを持っていないし、あなたの一部が私を育てることを願っています！ここで

は、Eclipseのエラーです：

Could not open the editor: The editor class could not be instantiated. This usually indicates a missing no-arg constructor or that the editor's class name was mistyped in plugin.xml.

Answer 1

最新のEclipseバージョンを公式サイトからダウンロードして、すべてがうまく動かなくてはなりませんでした。 aptパケットを使用しないでください。これは、サポートされていない古いバージョンのEclipseを指しているためです。

Answer 2

私はcom.ibm.icu.util.StringTokenizerクラスがロードされていない場合、Ubuntuのビルドがちょうど壊れている疑いがあります。これは、com.ibm.icuバンドルによって提供されています。これは、プレーンなEclipse Platformのダウンロードで提供されています。
