How to prevent from overriding parent pom dependency version in child pom

Question

I have parent pom with such config:

<dependencyManagement>  
    <dependencies>
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.2.9</version>
        </dependency>
    </dependencies>
</dependencyManagement>

And my child pom:

<dependencies>
    <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.3.5</version>
    </dependency>
</dependencies>

I want to use 4.3.5 version in my classpath, because at the moment I am getting error, parent version should not be modified:

java.lang.NoClassDefFoundError: org/apache/http/impl/client/HttpClients

Any ideas how to prevent from overriding that 4.2.9 version?

Answer 1

As you know that your parent pom dependency is include in the child pom then don't need to write dependency in the child pom.xml . To include the parent pom dependency in child use

<dependency>
            <groupId>${defined groupId of parent}</groupId>
            <artifactId>${artifact defined for parent }</artifactId>
            <version>${version defined for parent}</version>
        </dependency>

Answer 2

In your parent Pom file for the specified Dependency add scope as Provided

<dependencyManagement>  
    <dependencies>
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.2.9</version>
            <scope>provided</scope> 
        </dependency>
    </dependencies>
</dependencyManagement>

But As @Deltharis commented better to use the dependency only in the parent POM

Answer 3

I changed parent version to desired and removed dependency from child (the simple and the best solution). Thanks goues to @Deltharis for the comments!
