Maven release failing : A zip file cannot include itself - maven

Question

I am facing an issue while releasing a Maven project to nexus repository. I am doing this by Jenkins job. I am getting the error:
Failed to execute goal org.apache.maven.plugins:maven-source-plugin:3.0.1:jar (attach-sources) on project xyz: Error creating source archive: A zip file cannot include itself -> [Help 1]
I am using maven assembly plugin and external.atlassian.jgitflow:jgitflow-maven-plugin.
I have followed below article on StackOveflow : A zip file cannot include itself - Maven-assembly plugin
But this did not solve the problem. Below is how I am using the plugin

Can someone point me where I am making the mistake.
Thanks.
