Resolving same classes defined in different dependencies

Question

I'm running into a strange issue where I have two dependencies in my Maven file that both define BasicLineFormatter.class. The issue that I am running into is that one of my dependencies obviously uses a different version that the code is expecting and it throws and error.

How can I tell Maven that I want to use my standard http-core dependency for this class rather than the one that is causing an issue.

RESOURCE LOCATION: jar:file:/var/lib/tomcat8/webapps/ROOT/WEB-INF/lib/tika-app-1.10.jar!/org/apache/http/message/BasicLineFormatter.class

My pom.xml looks like this:

<groupId>xxx</groupId>

<name>xxx</name>

<dependencies>

    <dependency>

        <artifactId>commons-logging</artifactId>

    </dependency>

    <dependency>-->
        <groupId>org.apache.tika</groupId>
        <artifactId>tika-app</artifactId>
        <version>1.10</version>
    </dependency>
</dependencies>

My code is getting the BasicLineFormatter class from the Tika dependency which is causing the issue. I want it to be coming from my defined http-core which is the correct version. It also seems to be ignoring the ordering the dependencies in the file.

Use - Shade Plugin - https://maven.apache.org/plugins/maven-shade-plugin/examples/includes-excludes.html

Reference - Maven dependency: exclude one class
