'Could not transfer artifacts from/to central maven repo when using Spring Framework Cloud

I am trying to create a maven project using Spring Framework Cloud. I defined pom.xml file as below

When trying to build maven getting error for all dependencies as

Could not transfer artifacts from/to central (https://repo.maven.apache.org/maven2)

Multiple annotations found at this line: - Failure to transfer org.springframework:spring-orm:jar:4.2.6.RELEASE from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced.

When I go to the location, I can clearly see the Jar files are present in that location. Is there something else I need to add to my pom.xml?

javamavenpom.xmlspring-cloud

I tried the same pom.xml inEclipse IDE and surprisingly it worked there as it is.

To make it work on STS, I added following properties

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <start-class>io.pivotal.microservices.services.Main</start-class>
        <spring-cloud.version>Brixton.RELEASE</spring-cloud.version>
    </properties>

Refer Unable to download/import package org.springframework.cloud.config.server.EnableConfigServer

This worked for me, though I am still curious about the difference.

Try force refreshing your dependencies. Specifying -U does that

mvn clean install -U

Edit: You can purge your local release dependencies and to the normal mvn clean install afterwards:

mvn dependency:purge-local-repository

There is not way to force the release dependencies to be pulled, the -U only works with snapshot dependencies

Solution 3:[3]

I had the same error on my project and this is what worked for me.

First of all, go to your pom.xml and find your spring-parent version. Then go to https://repo.maven.apache.org/maven2/springframework/spring-parent and check if your same springframework version exists, if not change your springframework version to an existing one.
