我有一个像这样的属性文件（user.properties）：
vc.ip=10.161.22.102,10.161.19.112
adminUserName=admin
adminPassword=password
sshUserName=userName
sshPassword=password
所以我把它包括在内：
<property file="user.properties"/>
之后我可以将vc.ip称为$ {vc.ip}。
但之后我想分割vc.ip并将值（10.161.22.102和10.161.19.112）存储在不同的变量中。我怎样才能做到这一点？
我试过这个：
<script language="javascript">
project.setProperty('variable1', project.getProperty(${vc.ip}).split(',')[0]);
project.setProperty('variable2', project.getProperty(${vc.ip).split(',')[1]);
</script>
但是我收到以下错误：
project.setProperty('vcIp', project.getProperty(${vc.ip).split(',')[0]);
