我正在尝试使用“gdata-scala-client”导入使用 scala 的谷歌联系人。我按照这里的说明进行操作,这是我的示例代码
import com.google.gdata.Service
import com.google.gdata.data.StdAtomFeed
object Con extends App {
println("hey")
val s = new Service("comp-test-1.0", "cp") {}
s.setUserCredentials("scalaprogrammer1@gmail.com", "xxxxxxxx")
val atomFeed = new StdAtomFeed
val f = s.query("http://www.google.com/m8/feeds/contacts/scalaprogrammer1%40gmail.com/base", atomFeed.feedPickler)
for (e <- f) println(e.title)
}
但我得到了这个例外:

我是 scala 的新手,有人可以建议我在哪里缺乏吗?
