Eclipse Juno -断言失败(当从插件调用代码时出现问题:“org.eclipse.jface”)。

I recently installed Eclispe Juno for Java for Android. I usually press . after a class name to know the associated methods, in case I wish to choose some other method instead of one already chosen from this list the following error pops up in the IDE.

我最近为Android安装了Java的Eclispe Juno。我通常的新闻。在一个类名之后，要知道相关的方法，如果我希望选择其他方法，而不是从这个列表中选择的方法，那么在IDE中会出现以下错误。

How can tell IDE that this is not an error and there is no need to pop this message again and again?

如何告诉IDE这不是一个错误，并且不需要一次又一次地弹出这个消息?

The following is the error log from Eclipse

As mentioned before, the problem is caused by the plugin Coffee-Byte plugin for Eclipse. I managed to work-around the problem, for myself at least; disabled everything except Import Statements, Source Headers, Javadocs, and User Defined Regions. I had to manually add regions to the template of methods to get them to fold automatically, but it's a small price to pay for having custom folding.

如前所述，这个问题是由Eclipse的plugin Coffee-Byte插件引起的。我设法解决了这个问题，至少对我自己来说;禁用除导入语句、源头、Javadocs和用户定义区域之外的所有内容。我必须手动将区域添加到方法模板中，以使它们自动折叠，但对于定制折叠来说，这是一个很小的代价。

Also, if anyone is interested in fixing it, the error only occurs if Report problems as you type is enabled in Preferences->Java->Editor. If disabled, then all types of folding work.

另外，如果有人对修复它感兴趣，那么只有当您在首选项中启用了该类型的报告问题时才会出现错误——>Java->编辑器。如果禁用，则所有类型的折叠工作。

Update: I'm currently using Eclipse version Kepler Service Release 1, and build id 20130919-0819. I've re-enabled Normal Methods, Constructors, and Getters and setters; so far, the assertion error hasn't appeared. It seems that the problem has been fixed.

更新:我目前正在使用Eclipse版本的开普勒服务版本1，并构建id 20130919-0819。我重新启用了常规方法、构造函数、getter和setter;到目前为止，断言错误还没有出现。看来问题已经解决了。

Looks like the problem was caused by Coffee-Byte plugin of Eclipse (plugin used for folding) http://kosiara87.blogspot.in/2011/12/how-to-install-coffee-bytes-plugin-in.html?showComment=1341091754230#c8853438068212069468.

看起来这个问题是由Eclipse(用于折叠的插件)的咖啡字节插件引起的。
