java - eclipse "problems during content assist"弹出窗口

Question

在输入一些 Java 代码时，我点击了点/成员运算符 (.)，就像 ObjectName.methodName 中的点一样，并在 Eclipse 的弹出窗口中收到此错误:

The `org.elcipse.jst.ws.jaxws.ui.jaxwsjavacompletioncomputer` 
proposal computer from the `org.eclipse.jst.ws.jaxws.ui` 
plug-in did not complete normally.

第二个弹出窗口紧接着是消息:

"Cannot perform operation: The compilation unit 
is not in the build path of a Java project".

这是否意味着某些必需的库没有按需要安装？

Answer 1

来自 some of the occurrences out there ，看起来您当前的项目没有附加“Java 特性”。

检查项目属性。参见 if its .project file has a javanature in it .
