我将Tycho版本从0.25.0升级到1.1.0。现在，构建开始时很好，但后来失败了，出现了数百个错误，如：

... Compilation failure:
The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files

Answer 1

这可能是因为在运行时/调试期间没有几个插件/包。请访问您的项目“运行配置..”并转到插件选项卡。启用以下插件

 1. org.eclipse.equinox.ds
 2. org.eclipse.team.core
 3. org.eclipse.ui.trace
 4. org.eclipse.equinox.util
 5. org.eclipse.equinox.common 

然后单击右侧出现的“Add Required Plug-ins”按钮，并再次单击Apply和Run应用程序。

类似的bug已经在eclipse中报告过。你也可以参考这个。
