Maven: missing artifact org.springframework:spring:jar:4.2.6

I have a dynamic web project in SpringToolSuite.
It is converted into a Maven project.

I am getting the issue:


Mising artifact org.springframework:spring.jar:4.2.6


I already tried to clean, rebuild and run the project.
It gives:


Error reading file
C:\Users\jublikon.m2\repository\org\springframework\spring\4.2.6\spring-4.2.6.jar
C:\Users\jublikon.m2\repository\org\springframework\spring\4.2.6\spring-4.2.6.jar
(The system cannot find the specified file)


I do not understand why it is asking for jar files while I am using Maven?

I have already seen this post but somehow I am not able to solve my problem.

enter image description here

When I execute


mvn clean install


in the root directory of the project I get:

>mvn clean install

I have also checked my proxy settings. The active provider in eclipse is set to 'native' and I am not connected through a proxy

In the directory


~/.m2/settings.xml


main is org.apache.maven.cli.MavenCli from plexus.core

set maven.home default ${user.home}/m2

[plexus.core]
optionally ${maven.home}/lib/ext/*.jar
load ${maven.home}/lib/*.jar
load ${maven.home}/conf/logging

Answer

I'm quite sure there is no artifact called "spring"

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring</artifactId>           <!-- *** spring doesn't *** exist  -->
    <version>4.2.6</version>
</dependency>

Depending on the Spring components you need, you should basically include these dependencies:

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>4.2.6.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>4.2.6.RELEASE</version>
    </dependency>

In my Spring project, I include the Spring artifacts via a BOM (Bill of Materials):

<properties>
    <spring.version>4.2.6.RELEASE</spring.version>
</properties>

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