无法使用Tycho和Java 9构建Eclipse项目

Question

我的Eclipse项目使用Java 8构建得很好，但是Java 9失败了：

有什么办法解决这个错误吗？我试图设置MAVEN_OPTS=--add-modules java.se.ee，但这没有帮助。

我的JDK版本是9-ea+175。

更新

我将tycho版本从0.25.0升级到1.0.0。现在，构建很好地启动，但是后来失败了，有数百个错误，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/包可用。请访问您的项目"Run Configurations.."并转到Plug-ins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 

然后单击右侧的"Add Required Plug-ins“按钮，然后再次单击Apply和Run。

eclipse 月食虫中已经报告了类似的bug。你也可以参考这个。
