Cannot access repo.spring.io for Spring-boot exercises

Question

I'm looking at spring-boot at the moment, but cannot access the repo.spring.io maven repository in builds.

I've created the initial Gradle build file , but receive a 401 (Unauthorised) response when I try to run the build for the first time. I've tried pulling down the POM/JARs manually (to manually deploy to my local repo), but again receive 401.

If I browse to the relevant folder and click on the JAR (POMS seem to be OK), I receive a 401 error here too (response is: The server http://repo.spring.io:80 requires a username and password. The server says: Artifactory Realm)

Can someone direct me to a repo I can actually pull these files from? Alternatively, can someone direct me to where I can get credentials for this repo?

Thanks

Answer 1

repo.spring.io lazily caches the contents of Maven Central. You don't say which dependency it is that's causing a problem, but I believe the problem that you're seeing is that you're attempting to access an artifact that has yet to be cached. This will result in a 401 response.

Trying adding mavenCentral() to the configured repositories in build.gradle. For example:

repositories {
    mavenCentral()
    maven { url "https://repo.spring.io/milestone" }
}

repo.spring.io is no longer serving through plain http. Check your gradle (pom.xml, etc) file for http://repo.spring.io and change it to https://repo.spring.io

The relevant maven error message is similar to this:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.8.2:site (default-site) on project tidy-up: SiteToolException: The site descriptor cannot be resolved from the repository: ArtifactResolutionException: Unable to locate site descriptor: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:xml:site_en:2.2.4.RELEASE from/to springplugins (http://repo.spring.io/plugins-release/): Access denied to: http://repo.spring.io/plugins-release/org/springframework/boot/spring-boot-starter-parent/2.2.4.RELEASE/spring-boot-starter-parent-2.2.4.RELEASE-site_en.xml , ReasonPhrase:Forbidden.

Answer 3

repo.spring.io is no longer serving through plain http.

1- Check your pom.xml file for http://repo.spring.io/plugins-release/

2- and change it to https://repo.spring.io/plugins-release/

like below

<repositories>
  <repository>
    <id>spring-repo</id>
    <url>https://repo.spring.io/plugins-release/</url>
  </repository>
</repositories>
