Eclipse插件 - 引起：java.lang.ClassNotFoundException：无法找到clazz

Question

我已经成功创建了一个Eclipse插件，我添加了一个命令，以便用<xsl:text>包装一些文本。

我的环境是Win 7 x64，Eclipse Mars，Java 1.7。

为了实现这个功能，我只是复制/粘贴了org.eclipse.wst.sse.ui.internal.handlers.ToggleLineCommentHandler类，后者又使用了一些内部类，其中包括CommentingStrategy。

我知道非API类在插件MANIFEST中被标记为x-friends，因此它会在编译时出现错误，您可以关闭它，因为在我的情况下是警告......

但是在运行时我尽管我的插件依赖项设置正确，但仍然收到以下错误：

这是我的宣言：

那么，是否绝对禁止使用eclipse内部类？

如果是这样，我怎样才能实现我的目的，即通过用<xsl:text>标记围绕它们来简单地对XML文件中的某些字符进行纹理化，就像ToggleLineComment一样。

感谢您的回答！
