Eclipse的自动完成一些Java文件不工作 [英] Eclipse autocomplete not working in some Java files

问题描述

我注意到，自动完成没有在一些在Eclipse Java文件的工作。
此外，在自动完成不工作的文件，显示一个中空的J为Java文件的图标。其中，自动完成工作，对Java文件的图标是一个充满J的文件

I have noticed that autocomplete is not working in some of java files in Eclipse. Also, the files where autocomplete is not working, display a hollow "J" as the icon for the Java file. The files where autocomplete is working, icon for java file is a filled "J"

我想知道，如果有人可以点出了什么毛病都suddent，为什么图标的变化，为什么自动完成和语法高亮是关断的文件，一个空心J的图标？

I am wondering if someone can point out what went wrong all of suddent, why the change in icons and why autocomplete and syntax highlighting is turned-off in the files with a hollow "J" icon?

感谢。

更新

基本上，我在做什么VonC曾建议但是Eclipse并没有令人耳目一新，这就是为什么我在想，VonC的建议不工作，做了刷新后，问题解决了。

Basically, I was doing what VonC has suggested but Eclipse was not refreshing that it why I was thinking that VonC's suggestion isn't working, after doing a refresh, the problem resolved.

推荐答案

在此下面的图片， MyClass.java 有一个中空的Ĵ，因为它明确地从源头上排除建：

In this following picture, MyClass.java has a hollow J, because it is explicitly excluded from the sources to build:

你能去该项目的性质， Java构建路径节来源选项卡看看一些排除过滤器已设置？结果
这是通常例如定义：

Could you go to the properties of the project, "Java Build Path" Section, "Source" tab and see if some exclusion filter has been set ?
It is usual for instance to define:

**/Test*.java

在第一次构建任何单元测试类排除（当你有一大套的来源，不希望自动完成过程中与测试类psented $ P $，或者不想让他们在源搜索考虑）

to exclude at first building any unit-test class (when you have a large set of sources and do not want to be presented with Test classes during auto-completion, or do not want them considered during source searches).
