Question

过去几天我花了一些时间将Eclipse E4插件项目的构建过程转移到maven和tycho。在我开始工作之后，我想再次看一下producr并试图通过RunAs“xvy.product”启动它。我希望工作正常，但我收到此错误消息：

applicationXMI parameter not set and no branding plugin defined.

最后看起来，我自己的代码似乎没有任何问题？！经过一些谷歌搜索后，我终于发现了一些类似的错误：这个问题在stackoverflow Eclipse 4 RCP Deployment applicationXMI argument missing进行了讨论，但我没有收到 AssertionFailedException也不尝试导出RCP产品。另一个出现是eclipse.org上的一个错误Application.e4xmi should be default for "applicationXMI" 因此，我查看了我的plugin.xml，它看起来像这样：

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

   <extension
         id="prod"
         point="org.eclipse.core.runtime.products">
      <product
            application="org.eclipse.e4.ui.workbench.swt.E4Application"
            name="FinPim">
         <property
               name="appName"
               value="FinPim">
         </property>
         <property
               name="applicationXMI"
               value="mhFinPim/Application.e4xmi">
         </property>
         <property name="lifeCycleURI" value="bundleclass://mhFinPim/de.mho.finpim.lifecycle.Manager"></property>
      </product>
   </extension>

</plugin>

你可以在这里看到，我的applicationXMI指向mhFinPim / Application.e4xmi ，这是bundlename / Applicatione4xmi 那么，现在我想知道，还有什么可能是错误的，这会阻止我的产品开始？

在此例外之后，我再收到一个：

    at org.eclipse.equinox.launcher.Main.main(Main.java:1472)

我想，这只是由第一个异常引起的后续错误？

在Eclipse E4中启动产品时“applicationXMI参数未设置”
