Question

我是Eclipse RCP的新手。我尝试使用默认项目资源管理器在E4的基础上构建一个RCP项目。我找到了这两个教程：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

毕竟我有一个带有部件的窗口但是没有加载项目浏览器。这是来自log的stackstrace。

这是我的plugin.xml

<?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>

我尝试了谷歌的所有tipps，但我不知道该怎么做。

感谢您的帮助！

我在this tutorial中从头开始创建了一个新的RCP项目，但它确实有效。在此之后，我意识到原始项目的pom.xml与新项目的pom.xml不同。

<?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。下一个问题是第二个扩展点必须定位到相同的id：id =＆＃34; spside.rcp.perspective＆＃34;如Application.e4xmi。

无法创建类CompatibilityView
