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

Question

我使用 Eclipse 4.3.0 开发插件/RCP。在尝试按照插件开发 101 进行 RCP 产品时，第 2 部分:富客户端应用程序简介 http://www.ibm.com/developerworks/library/os-eclipse-plugindev2/作者 Chris Aniszczyk，2008 年，从 .product Overview 选项卡单击 Launch an Eclipse application 时出现以下错误。

更多信息

注意:Use existing product 中没有rcp.product 选项(我认为这绝对是教程中的错误)

Answer 1

如果您使用的是 .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 文件目前没有依赖项，因此不会找到任何内容!选项卡上有一个 Add Required 按钮，可以添加所需的所有内容。

注意:该教程看起来像是在使用旧版本的产品文件，该文件依赖于“配置”选项卡。

更新:要获得正确的依赖项，请先添加您自己的插件，然后按 Add Required 这将添加很多额外的插件。对于 Eclipse 4.3.1 上的一个非常相似的插件(具有不同的名称)，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>
