我的Eclipse RCP Maven项目使用Java 8构建良好，但在Java 9中失败：

有任何想法如何解决此错误？我尝试设置MAVEN_OPTS=--add-modules java.se.ee，但这没有用。
我的JDK版本为9-ea+175。
我将tycho版本从0.25.0升级到1.0.0。现在构建开始很好但后来失败了数百个错误，如：
... Compilation failure:
The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files
答案 0 :(得分：2)
这可能是因为在运行时/调试期间没有可用的少数插件/捆绑包。请访问您的项目"Run Configurations.."，然后转到Plug-ins标签。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
，然后单击右侧的“ Add Required Plug-ins”按钮，然后再次单击Apply和Run应用程序。
在月食Eclipse Bug中已经报告了类似的错误。您也可以参考这个。
