401 嘗試解析 org.gradle.api.plugins:gradle-tomcat-plugin:1.2.4 時未授權

Question

So, I am trying to build the sample spring security saml project provided in https://docs.spring.io/spring-security-saml/docs/1.0.x/reference/html/chapter-quick-start.html but i嘗試構建時出現以下錯誤：

* 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

我找不到明確的解釋，但即使我嘗試導航到https://repo.spring.io/plugins-release/org/gradle/api/plugins/gradle-tomcat-plugin/1.2.4/gradle-瀏覽器上的tomcat-plugin-1.2.4.pom我得到同樣的錯誤。

任何想法，將不勝感激！

您好我有同樣的問題，根據這個答案，這是由於 spring repos 緩存工件，當工件尚未被緩存時，它返回 401。我解決了這個問題，只需將jcenter添加到我在gralde.build如下：

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