Eclipseプラグインの開発では、CompilationUnitEditor、という名前のカスタマイズされたソースビューア、IJavaEditorTextHoverを拡張するエディタをカスタマイズします。 はplugin.xmlので、私は自分のエディタのテキストホバーを作成するEclipseプラグインの開発でエディタのテキストホバーを作成できません
plugin.xml エラーとしてorg.eclipse.jdt.ui.javaEditorTextHoverの拡張機能を作成します。

ありがとう、私はJavaEditorを拡張するためにエディタを改訂し、 "メッセージはJavaテキストホバー を作成できませんでした" – csytang
