ANT configuration Ant_home is set incorrectly or ANT could not located_ant configuration

The reason ant almost got killed.

When I built ANT, I did it for half a day, and it was still an error in the command line: Ant_home is set incorrectly or ANT could isn't be located. Please set ant_home. I check the steps:

1, JDK installed Ah, java_home configuration ah: java_home:e:\java\jdk1.5.0_06;

2, Ant decompression in e: Disk AH

3, Path added to Ant's Bin directory ah: path:e:\ant\apache-ant-1.8.1\bin;

4, environment variable ant_home is also to ANT decompression directory yes: ant_home:e:\ant\apache-ant-1.8.1;

I faint ... You guess what, ant_home configuration, can not add a semicolon; I removed the semicolon, oak. Hey......
