forcing maven to use local dependency - maven

Question

I'm stuck with a problem which may seem silly, but I don't know how to resolve it. I also looked online, but none of the solutions work for me.
I have a spark code which is using the spark graphX module. I need to make changes inside the graphX and force my project to use this modified version of the graphX. In order to do that, I have first taken out the graphx module from spark source code and compiled it independently. Then I specify the dependency in my application pom.xml file, which has the scope of "system". There is my application pom.

When I compile my code, it still downloads the graphx dependency and seems like it uses the original jar file during the runtime as well. I really don't know how to resolve this issue. Any help would be appreciated.

Answer 1

spark-mllib contains a dependency on spark-graphx. You should exclude it in your pom.xml :
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-mllib_${scala.binary.version}</artifactId>
<version>${spark.version}</version>
<exclusions>
<exclusion>
<groupId>org.apache.spark</groupId>
<artifactId>spark-graphx_${scala.binary.version}</artifactId>
</exclusion>
</exclusions>
</dependency>
