ant操作cvs commit

网上cvs login 用法 ，我尝试了好几次都不行，就直接使用command
<cvs  command="login -ppasswd"  cvsroot=":pserver:${cvs.user}@${cvs.host}:/SourceCode" />

ok

<?xml version="1.0"?>

<project default="main" basedir=".">

<property name="cvs.user" value="yuj"/>

<property name="cvs.host" value="192.168.1.xxx"/>

<property name="cvs.passfile" value="passwd"/>
