At least one Instantiations product installed into this version of Eclipse was compiled

做插件开发的时候遇到了这个问题，百度竟然都找不到答案耶，难道都没有人遇到这个诡异的问题嘛！

问题描述：
启动项目的时候突然报这个错了

过了一小会会，还会弹出这个框
Incorrect version product
At least one Instantiations product installed into this version of Eclipse was compiled and built for a different version of Eclipse

This version of SWT Designer was compiled for Eclipse 3.6 but is running on Eclipse 3.3.
This version of RIM Designer was compiled for Eclipse 3.6 but is running on Eclipse 3.3.
This version of WindowBuilder was compiled for Eclipse 3.6 but is running on Eclipse 3.3.
This version of Shared was compiled for Eclipse 3.6 but is running on Eclipse 3.3.

这个诡异的问题竟然连我的师父——一名从事IT行业多年的资深大龄单身男性程序员，都束手无策。
我为什么要在此提到我的师父呢，是因为我寄几在机缘巧合之下，也出现了这个错误，发现了这个问题的形成原因以及解决办法（先叉会腰~~~）
原因就是

我又开了一个eclipse，我打开了一个sts，所以就出现了这个问题，把sts关掉，就好了！！！

因为我在这个插件项目里加了Gson包，这个在日志文件里也显示了

估计是Gson jar包的版本跟这个不兼容，所以就把我加上去的Gson那两行去掉，就大功告成了！！！
