Eclipse RCP java.lang.ClassNotFoundException：org.eclipse.core.runtime.adaptor.EclipseStarter

Question

我使用Eclipse 4.3.0开发插件/ RCP。 在插件开发101，第2部分：Chris Aniszczyk 2008引入富客户端应用程序http://www.ibm.com/developerworks/library/os-eclipse-plugindev2/时，尝试执行RCP产品时，从.product概述选项卡中单击Launch an Eclipse application时出现以下错误。

注：有在Use existing product没有rcp.product选项（我认为这是在教程中明确的错误）

Answer 1

如果您使用.product文件，则必须在Dependencies选项卡上添加所有插件或功能依赖项。您的rcp.product文件目前没有相关性，因此无法找到任何内容！该选项卡上有一个Add Required按钮，该按钮应添加所需的所有内容。

注意：该教程看起来像使用的产品文件的旧版本与配置选项卡上存在依赖关系。

更新： 要想获得正确的依赖关系，首先添加自己的插件，然后按Add Required，这将添加很多额外的插件。对于基于Eclipse 4.3.1非常相似的插件（使用不同的名称），我得到：

<?xml version="1.0" encoding="UTF-8"?> 
<?pde version="3.5"?> 

<product application="TestRCPView.application" useFeatures="false" includeLaunchers="true"> 

    <configIni use="default"> 
    </configIni> 

    <launcherArgs> 
     <vmArgsMac>-XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts</vmArgsMac> 
    </launcherArgs>

Answer 2

apt autoremove eclipse* --purge 
apt autoremove libosgi* --purge 

如果你有，那么也删除此英国媒体报道：

apt autoremove libmaven* --purge 
apt autoremove libsisu* --purge 

然后再安装回：

apt install eclipse-cdt 

您还将获得C++索引器。
