今晚使用CheckStyle在Eclipse里面通过Ant检查项目Java代码时，遇到以下的异常：

[CheckStyleTask] Running Checkstyle 5.5 on 159 files

Google了一下，网上说是CLASS_PATH出错了，也没明白怎么出错了，又有人说是使用了旧版本的antlr库，盯着天花板想了想，前几天确实将Ant从eclipse的plugin 1.7.1替换成了单独的1.8.2，于是，嗯，就解决问题了。下面详细记录下我的环境

Eclipse 3.5 Galileo
Apache Ant 1.8.2

解决办法

按照Ant自带的安装教程 %ANT_HOME%/docs/manual/install.html上所说的设置好Ant的class path信息，以Eclipse 3.5 Galileo为例

  1. 选择菜单Window->Preference
  2. 点开Ant->Runtime
  3. 点击"Ant Home..."按钮，选择%ANT_HOME%的具体路径
  4. "Ant Home Entries"的列表load完之后，选中其中的%ANT_HOME%/lib/antlr-2.7.7.jar，然后点击"Remove"按钮删除之
  5. 然后，问题就解决了。
