编译失败 - 无法从 https://maven.repository.redhat.com/ga/javax/servlet/javax.servlet-api/maven-metadata.xml 加载 Maven 元数据

Question

Literally just hit up key in my command line to get the last command to compile my java project. Is this a combination of updatePolicy and a server error on RedHat side?

I'm not behind a proxy or anything, did not change anything.

Could not resolve all files for configuration ':compileClasspath'.

Could not resolve javax.servlet:javax.servlet-api:3.+. Required by: project : Failed to list versions for javax.servlet:javax.servlet-api. Unable to load Maven meta-data from https://maven.repository.redhat.com/ga/javax/servlet/javax.servlet-api/maven-metadata.xml . Could not HEAD ' https://maven.repository.redhat.com/ga/javax/servlet/javax.servlet-api/maven-metadata.xml '. Received status code 500 from server: Internal Server Error

If this is an issue with RedHat though, I should be seeing more issues streaming in but I don't so it makes me believe it's an issue on my side but can't think of anything on my side.

edit 1: in my build.gradle I can see maven { url "https://maven.repository.redhat.com/ga/" }

can this be changed to an address that is not failing?

Answer 1

It looks like an issue on Redhat maven repository side, the server seems down: if you try to download manually some artefacts you also get 500 errors: eg : https://maven.repository.redhat.com/ga/javax/

You can add other repositories in your repositories block :

repositories {
    jcenter()
    mavenCentral()

}

These two repositories should allow you to resolve all "standard" libraries in RELEASE version. You did not specify in your question which version of the servlet-api you need, but it should be there.

EDIT see https://access.redhat.com/articles/3620281 that can explain service down
