我有9个jar文件在我的项目/ lib文件夹和我的类路径似乎是准确的。在我编译之前，一切正常，但是在编译单个jar之后，stringtree-json-2.0.5.jar在我尝试运行它时抛出ClassNotFoundException异常。单个jar抛出ClassNotFoundException后我编译
事情我已经尝试：
- Using '*' to load everything in my lib folder at once
- 使用杰克逊交换（假设它是罐子具体），但Stringtree具有完全相同的问题。这个问题jar只是一个json解析器，我只用了一次（在关键领域）。
- 尝试在编译之前和之后改变类路径以确保其正确。
- 也许还有更多我不记得......一直停留一个星期左右。
这里的错误，因为它是抛出：

我使用Eclipse来开发和编译。解决此问题的重复建议之一是将项目导出为可运行Jar文件。但是，这是一个插件，因此没有“主要”方法。
有没有其他想法呢？我觉得我已经筋疲力尽（...我自己和）我在google和stackoverflow上找到的所有选项。
谢谢！
