我继承了一个现有的RCP项目,我对这种类型的项目如何运作完全不了解。
我正在为Java Developers运行Eclipse IDE(版本:Oxygen.3 Release(4.7.3))。
当我尝试将项目作为Eclipse应用程序运行时,出现以下错误:
java.lang.NullPointerException

我已经看到了针对此问题的一些解决方案,说org.eclipse.equinox.ds
和org.eclipse.equinox.event
需要包含在插件依赖项中,但这并没有解决我的问题。
答案 0 :(得分:1)
要解决此问题,我执行了以下操作:
x
按钮,关闭org.eclipse.equinox.event
插件org.eclipse.equinox.event
添加到开始级别并将Auto-Start
设置为true
