我只是想动手使用 Spray 库，但是由于 maven 依赖性而无法执行它的示例。

正如文档中所提供的，我已将 Spray 存储库定义如下：

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

然后我定义了它的依赖如下：

  <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>

但是，当我尝试执行 maven 安装时，我遇到以下错误：

[错误] 无法在项目 spray-test1 上执行目标：无法解析项目 org.spray:spray-test1:jar:1.0-SNAPSHOT 的依赖项：无法收集 [io.spray:spray-http:jar:1.1 的依赖项-M7 (编译), io.spray:spray-httpx:jar:1.1-M7 (编译), io.spray:spray-util:jar:1.1-M7 (编译), com.chuusai:shapeless_2.9.2:jar: 1.2.0（编译）]：无法读取 io.spray:spray-http:jar:1.1-M7 的工件描述符：无法将工件 io.spray:spray-http:pom:1.1-M7 从/到 sprayrepo 传输（http://repo.spray.io/）：连接超时 http://repo.spray.io/io/spray/spray-http/1.1-M7/spray-http-1.1-M7.pom -> [帮助 1] [错误]

任何指针或建议将不胜感激。

谢谢
