Failure to find org.springframework.cloud:spring-cloud-dependencies:pom

Question

I have been trying to set up a spring boot project but am getting an error. I researched and tried various options but no luck so far. Any help would be appreciated.

The pom.xml file:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

<groupId>com.sysyaas.pardakhtyary</groupId>
<artifactId>auth</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>master</name>
<packaging>jar</packaging>
<description>Auth Server Pardakhtyary</description>

Answer 1

You need to specify ${spring-cloud.version}. Add properties section into your pom:

    <properties>
        <spring-cloud.version>Greenwich.RELEASE</spring-cloud.version>
    </properties>

Ofc, instead of "Greenvich.RELEASE" you can use any other version of spring-cloud-dependencies

Answer 2

Well, you commented out

<!--<properties>-->
    <!--<java.version>1.8</java.version>-->
    <!--<spring-cloud.version>Finchley.M8</spring-cloud.version>-->
<!--</properties>-->

So Maven has no idea how to get the placeholder for

<version>${spring-cloud.version}</version>

Un-comment these lines and you should be good to go.
There is also a new version for that module, Greenwich.RELEASE.
