使用简单查询的Anorm 2.4-SNAPSHOT隐式转换错误

Question

我正在尝试使用Anorm docs逐字记录的示例：

import anorm._ 

DB.withConnection { implicit c =>
  val result: Boolean = SQL("Select 1").execute()    
} 

我收到了这个错误：

[error] /Users/Greg/git/slurpee/src/test/scala/ReaderTests.scala:115: type mismatch;
[error]  found   : anorm.SqlQuery
[error]  required: ?{def execute: ?}
[error] Note that implicit conversions are not applicable because they are ambiguous:
[error]  both method sqlToSimple in package anorm of type (sql: anorm.SqlQuery)anorm.SimpleSql[anorm.Row]
[error]  and method sqlToBatch in package anorm of type (sql: anorm.SqlQuery)anorm.BatchSql
[error]  are possible conversion functions from anorm.SqlQuery to ?{def execute: ?}
[error]                 SQL("select 1;").execute()

这是2.4特有的吗？

applicius'评论是正确的 - 稳定版本逐字逐句。一定是SNAPSHOT版本的一些问题。它发生了。
