Re: [pdt-dev] org.eclipse.wst.sse.ui.semanticHighlighting extension

[赵忠伟 <zhaozhongwei@xxxxxxxxxxxxxxxx>]

hi,

Does this patch work?

2011/6/27 Robert Gründler <r.gruendler@xxxxxxxxx>

Hi again,

i tried to follow the Wiki entry to add SemanticHighlighting to my plugin for
PHP Annotations:

http://wiki.eclipse.org/PDT/Dev2Dev/Semantic

by adding an extension point like this:

<extension
      point="org.eclipse.wst.sse.ui.semanticHighlighting">
<highlighting
         class="org.eclipse.symfony.ui.editor.highlighting.AnnotationHighlighting"
         target="org.eclipse.php.core.phpsource">
</highlighting>
</extension>

I'm getting a ClassNotFoundException during startup for org.eclipse.symfony.ui.editor.highlighting.AnnotationHighlighting,
although my plugin is exporting the necessary packages.

According to the eclipse irc channel, the way the SemanticHighlighting extensions are loaded by the PDT plugin will only work for internal pdt-bundle classes (in SemanticHighlightingManager line 71).

Is this a bug in PDT or am i just not providing the extension point correctly?

thanks!

-robert
