所以，我正在尝试构建https://docs.spring.io/spring-security-saml/docs/1.0.x/reference/html/chapter-quick-start.html 中提供的示例 spring security saml 项目，但在尝试构建时出现以下错误：

* What went wrong:
A problem occurred configuring root project 'spring-security-saml'.
> Could not resolve all artifacts for configuration ':classpath'.
   > Could not resolve org.gradle.api.plugins:gradle-tomcat-plugin:1.2.4.
     Required by:
         project :
      > Could not resolve org.gradle.api.plugins:gradle-tomcat-plugin:1.2.4.
         > Could not get resource 'https://repo.spring.io/plugins-release/org/gradle/api/plugins/gradle-tomcat-plugin/1.2.4/gradle-tomcat-plugin-1.2.4.pom'.
            > Could not GET 'https://repo.spring.io/plugins-release/org/gradle/api/plugins/gradle-tomcat-plugin/1.2.4/gradle-tomcat-plugin-1.2.4.pom'. Received status code 401 from server: Unauthorized

我找不到明确的解释，但即使我尝试在浏览器上导航到 https://repo.spring.io/plugins-release/org/gradle/api/plugins/gradle-tomcat-plugin/1.2.4/gradle-tomcat-plugin-1.2.4.pom，我也会遇到同样的错误。

任何想法都将不胜感激！

您好，我遇到了同样的问题，根据this 的回答，这是因为 spring repos 缓存工件并且当工件尚未被缓存时它返回 401。我解决了这个问题，只需将jcenter 添加到我在gralde.build 中配置的存储库中，如下所示：

repositories {
         jcenter()
         maven { url "https://repo.spring.io/plugins-release" }
}
