无法执行喷雾示例| Maven依赖关系错误

Question

我只是想试试Spray库，但是由于maven的依赖性，无法执行它的示例。

如在文档提供我已经定义了喷雾库如下：

<repositories> 
     <repository> 
      <id>sprayrepo</id> 
      <name>spray repo</name> 
      <url>http://repo.spray.io/</url> 
      <layout>default</layout> 
     </repository> 
</repositories> 

然后如下我定义的依赖：

<dependency> 
      <groupId>io.spray</groupId> 
      <artifactId>spray-http</artifactId> 
      <version>1.1-M7</version> 
     </dependency> 
     <dependency> 
      <groupId>io.spray</groupId> 
      <artifactId>spray-httpx</artifactId> 
      <version>1.1-M7</version> 
     </dependency> 
     <dependency> 
      <groupId>io.spray</groupId> 
      <artifactId>spray-util</artifactId> 
      <version>1.1-M7</version> 
     </dependency> 
     <dependency> 
      <groupId>com.chuusai</groupId> 
      <artifactId>shapeless_2.9.2</artifactId> 
      <version>1.2.0</version> 
     </dependency> 
    </dependencies> 

然而，当我尝试执行到Maven安装，我面对以下错误：

[ERROR] Failed to execute goal on project spray-test1: Could not resolve dependencies for project org.spray:spray-test1:jar:1.0-SNAPSHOT: Failed to collect dependencies for [io.spray:spray-http:jar:1.1-M7 (compile), io.spray:spray-httpx:jar:1.1-M7 (compile), io.spray:spray-util:jar:1.1-M7 (compile), com.chuusai:shapeless_2.9.2:jar:1.2.0 (compile)]: Failed to read artifact descriptor for io.spray:spray-http:jar:1.1-M7: Could not transfer artifact io.spray:spray-http:pom:1.1-M7 from/to sprayrepo (http://repo.spray.io/): connection timed out to http://repo.spray.io/io/spray/spray-http/1.1-M7/spray-http-1.1-M7.pom -> [Help 1] [ERROR]

任何指针或建议将高度赞赏ated。

试试这个：

    <scala.tools.version>2.10</scala.tools.version> 
    <scala.version>2.10.2</scala.version>
