Eclipse编辑java文件报Unhandled event loop exception错误的解
本人Eclipse版本是”eclipse-jee-kepler-SR2-win32-x86_64“java
昨天由于换电脑，因此重装了一下软件，装好eclipse以后eclipse是可使用的（换电脑以前也一直是用这个版本）。后来又装了其余一些软件， 为了工做效率，只有边装软件边coding。后来发现再次在Eclipse中编辑java文件就一直会弹出错误提示框。如图。app
点开图下面的“Unhandled event loop exception"查看具体的错误，详细错误以下。eclipse

一大堆的错误信息，看不懂。上网搜了下，有的说是要把eclipse目下的Features目录和Plugins目下的全部带有org.eclipse.ui字样目录和jar给删掉。试了下也仍是问题照旧。this
没办法，只有删掉Eclipse，从新安装一个完整的试试。去官网上从新下载了”eclipse-jee-kepler-SR2-win32-x86_64“这个版本，结果一样的问题仍是会出现。spa
发如今错误消息中有一个是关于Git的，详细信息以下：rest
Warning: The environment variable HOME is not set. The following directory will be used to store the Git
user global configuration and to define the default location to store repositories: 'C:\Users\Administrator'. If this is
not correct please set the HOME environment variable and restart Eclipse. Otherwise Git for Windows and
EGit might behave differently since they see different configuration options.
This warning can be switched off on the Team > Git > Confirmations and Warnings preference page.

感受是否是由于安装Git的缘由？ 由于个人Git目录是装在”D:\Program Files (x86)“下，首先感受应该是由于目录中有空格，多是由于它引发来的。而后果断重装下Git，把目录放在”D:\Gi“下。重装好Git以后，重启 Eclipse，再编辑java文件，问题仍是出现了。
无心间在知乎上看到也有人碰到相似的问题，有人回复说把 百度杀毒 关了就行了。本身也正好运行着百度杀毒呢。而后立马把百度杀毒给关了。重启Eclipse，在编辑java文件，发现问题解决了。为了验证就是百度杀毒引 起来的，我有开启了百度杀毒，而后又重启Eclipse，编辑java文件，结果问题又出现了。关了百度杀毒就行了。
看来真是百度杀毒引发来的（百度杀毒是由于安装一个软件强制给装上的，当时感受既然装了，就用下吧）。果断卸掉！
