一个ant简单问题
为什么报这个错误呢,
element   type   "project "must   be   followed   by   either   attribute   specfiication  
, "> "or   "/> "
可是我明明有结尾呀...

我是按照书上操作的,build.xml文档也没有错误呀
<?xml   version= "1.0 "   encoding= "UTF-8 "?>
<project   name= "base "default= "run "basedir= ". ">
<property   name= "src "value= "src "/>
<property   name= "dist "value= "classes "/>
<property   name= "hello_jar "value= "hello.jar "/>
<target   name= "init ">
<mkdir   dir= "${dist} "/>
</target>
<target   name= "compile "   depents= "init ">
<javac   srcdir= "${src} "destdir= "${dist} "/>
</target>
<target   name= "build "   depends= "compile ">
<jar   jarfile= "${hello_jar} "   basedir= "${dist} "/>
</target>
<target   name= "run "depends= "build ">
<java   classname= "antdemo.HelloWorld_ant "classpath= "${hello_jar} "/>
</target>
</project>

------解决方案--------------------
这不叫ANT的问题.是你的问题.要注意XML中Element的多个属性要用空格隔开.
