Question

如何将TextEditor与某个文件关联？（Eclipse插件开发）

我确实喜欢下面，但是错了，我无法弄明白。我看过docs

   <!-- git -->
   <extension
         point="org.eclipse.ui.editors">
      <editor
            class="org.eclipse.ui.editors.text.TextEditor"
            contributorClass="org.eclipse.ui.texteditor.BasicTextEditorActionContributor"
            default="true"
            extensions="gitignore,gitmodules,gitattributes"
            icon="icons/git.ico"
            id="org.eclipse.ui.DefaultTextEditor"
            name="Text Editor">
      </editor>
   </extension>
