[英]Class not found exception in java though I have the jar file

原文 2016-12-04 16:17:02 0 1 java/ eclipse/ classnotfoundexception

I had a properly working eclipse project until this afternoon, when I closed my eclipse workspace (nothing special happened, but it closed a little bit slower than usually).我有一个正常工作的 eclipse 项目，直到今天下午我关闭了我的 eclipse 工作区（没有发生什么特别的事情，但它关闭的速度比平时慢了一点）。 When I restarted my eclipse a few hours later, I got a class not found exception.几个小时后，当我重新启动我的日食时，我遇到了一个未找到类的异常。

I think that somehow (I am not sure how, because I did not use my computer in the mean time), I broke the class path.我认为不知何故（我不确定如何，因为我当时没有使用我的电脑），我打破了课程路径。 I tried to import the missing jar file again, but it did not work because我试图再次导入丢失的 jar 文件，但它不起作用，因为

I already have it under the plugin dependencies我已经在插件依赖项下有了它
There are at least 20 imported jar files, and as I realized I can not delete just one, I have to remove the whole plug-in dependencies library, I and hope I do not have to import all of the other jar files again.至少有 20 个导入的 jar 文件，当我意识到我不能只删除一个时，我必须删除整个插件依赖库，我希望我不必再次导入所有其他 jar 文件。

Do you have any advice what can I try?你有什么建议我可以尝试吗？ I tried to look for similar cases, but most of them are usually a new project, which did not work before, and I just can not find the proper words for minimize the number of found solutions.我试图寻找类似的案例，但其中大多数通常是一个新项目，以前不起作用，我只是找不到合适的词来最小化找到的解决方案的数量。

Thank you!谢谢！

For each of my imported jar file, there were a number of access rules defined.对于我导入的每个 jar 文件，都定义了许多访问规则。 I removed the one, which name was forbidden */**, and now it works again.我删除了那个名字被禁止的 */**，现在它又可以工作了。
