为我的web项目使用ant build(Using ant build for my web project)

 事实证明，创建一个只有一个字段的新记录类型模式并不困难 - 我想用作关键字段，就像我上面的例子： 
 
{"name":"TestRecordKey", "type":"record", "fields":[
  {"name":"id", "type":"long"}
]}
 
 我在运行时这样做，因为我使用有效负载模式初始化我的Schema.Parser - 我只是以编程方式基于有效负载模式创建密钥模式。 
 
 希望不那么长期的解决方案，但这是有效的。 我仍然会投票并接受任何更清洁的解决方案。 

As it turns out, it wasn't that difficult just to create a new record-type schema with only one field -- the field I want to use as the key, like the example I have above:
 
{"name":"TestRecordKey", "type":"record", "fields":[
  {"name":"id", "type":"long"}
]}
 
I do it on the fly, as I initialize my Schema.Parser with the payload schemas -- I just create the key schema based on the payload schema programmatically.
 
Was hoping for a less long-hand solution, but this works. I'll still upvote and accept any solution that is cleaner.
