无法创建类CompatibilityView

Question

我是Eclipse RCP中的新成员。我尝试使用默认项目浏览器在E4的基础上构建RCP项目。我发现了这两个教程：dirksmetric.wordpress.com/2012/08/01/tutorial-eclipse-rcp-e4-with-3-x-views-like-project-explorer-properties-etc/ vogella.com/tutorials/ Eclipse4MigrationGuide/article.html

毕竟我有一个窗口的部分，但没有加载项目浏览器。这是来自日志的堆栈。

这个北京时间我的plugin.xml

<?xml version="1.0" encoding="UTF-8"?> 
<?eclipse version="3.4"?> 
<plugin> 
    <extension 
     id="product_spside" 
     point="org.eclipse.core.runtime.products"> <!-- org.eclipse.core.runtime.applications --> 

     <product application="org.eclipse.e4.ui.workbench.swt.E4Application" name="SPS IDE"> 
     <!-- org.eclipse.e4.ui.workbench.swt.E4Application -->  
     <property name="appName" value="SPS IDE"> </property> 
     <property name="applicationXMI" value="spside.rcp/Application.e4xmi"> </property> 
    </product> 
     <!-- <application> 
     <run 
      class="spside.rcp.Application"> 
     </run> 
    </application>--> 
    </extension> 
    <!-- <extension point="org.eclipse.ui.perspectives"> 
     <perspective 
      name="RCP Perspective" 
      class="spside.rcp.Perspective" 
      id="spside.rcp.perspective"> 
     </perspective> 
    </extension>--> 
</plugin> 

我试着从谷歌所有的窍门，但我不知道该怎么做。

感谢您的帮助！

我从零开始制作了一个新的RCP项目，就像this tutorial一样，它工作。在此之后，我意识到原始项目的pom.xml看起来不同于新项目。

<?xml version="1.0" encoding="UTF-8"?> 
<?eclipse version="3.4"?> 
<plugin> 

    <extension 
     id="application" 
     point="org.eclipse.core.runtime.applications"> 
     <application> 
     <run 
       class="spside.rcp.Application"> 
     </run> 
     </application> 
    </extension> 
    <extension 
     point="org.eclipse.ui.perspectives"> 
     <perspective 
      name="Perspective" 
      class="spside.rcp.Perspective" 
      id="spside.rcp.perspective"> 
     </perspective> 
    </extension> 
    <extension 
     point="org.eclipse.ui.views"> 
     <view 
      name="View" 
      inject="true" 
      class="spside.rcp.View" 
      id="spside.rcp.view"> 
     </view> 
    </extension> 
    <extension 
     point="org.eclipse.ui.perspectiveExtensions"> 
     <perspectiveExtension 
      targetID="*"> 
     <view 
       standalone="true" 
       minimized="false" 
       relative="org.eclipse.ui.editorss" 
       relationship="left" 
       id="spside.rcp.view"> 
     </view> 
     </perspectiveExtension> 
    </extension> 
    <extension 
     point="org.eclipse.ui.menus"> 
     <menuContribution 
      locationURI="menu:org.eclipse.ui.main.menu"> 
     <menu 
       label="File"> 
      <command 
        commandId="org.eclipse.ui.file.exit" 
        label="Exit"> 
      </command> 
     </menu> 
     </menuContribution> 
    </extension> 
<extension id="product_test" point="org.eclipse.core.runtime.products"> 
    <product application="spside.rcp.application" name="My Product"> 
    <property name="appName" value="SPS IDE"> </property> 
    <property name="applicationXMI" value="spside.rcp/Application.e4xmi"> </property> 
    </product> 
</extension> 
</plugin> 

我认为主要问题是我没有在第一个扩展中初始化3.x组件。接下来的问题是第二个扩展点必须针对相同的id：id =“spside.rcp.perspective”，如Application.e4xmi中所示。
