java - 无法解决 Gradle 依赖项的构建失败异常

Question

我最近开始研究 github 上提供的 spring 安全教程。我刚刚下载了 zip，当我在 eclipse 中导出项目并尝试“构建模型”时，它在下面给出了异常消息。

Could not resolve all dependencies for configuration ':runtime'.
> Could not resolve com.google.appengine:appengine-tools-sdk:1.4.2.
  Required by:
      :buildSrc:unspecified
   > Could not GET 'http://repo1.maven.org/maven2/com/google/appengine/appengine-tools-sdk/1.4.2/appengine-tools-sdk-1.4.2.pom'. Received status code 407 from server: Proxy Authorization Required
   > Could not GET 'http://repository.springsource.com/maven/bundles/release/com/google/appengine/appengine-tools-sdk/1.4.2/appengine-tools-sdk-1.4.2.pom'. Received status code 407 from server: Proxy Authorization Required
   > Could not GET 'http://repository.springsource.com/maven/bundles/external/com/google/appengine/appengine-tools-sdk/1.4.2/appengine-tools-sdk-1.4.2.pom'. Received status code 407 from server: Proxy Authorization Required

我刚刚删除了我在 eclipse 网络连接中提供的代理设置，在那种情况下我没有收到任何此类代理授权错误，只是无法解决问题。如果有人知道可能是什么原因？

build.gradle

repositories {
    mavenCentral()
    maven {
        name = 'SpringSource Enterprise Release'
        url = 'http://repository.springsource.com/maven/bundles/release'
    }
    maven {
        name = 'SpringSource Enterprise External'
        url = 'http://repository.springsource.com/maven/bundles/external'
    }
}

dependencies {
    compile 'com.google.appengine:appengine-tools-sdk:1.4.2'
}

Answer 1

你有

Proxy Authorization Required

错误字符串中的消息。您可能需要配置您的 Internet 连接代理设置。 (例如在 Internet Explorer -> 工具 -> Internet 选项中)

一般来说，检查提到的二进制文件版本是否真的在 Maven Central 上也是有意义的 http://mvnrepository.com/
