Gradle build: Exclude resources files from Spring Boot Jar file

I would like to exclude all config files from the jar file since they will be provided at the provisioning and having a different version in the build path may create some runtime issues. I am using the following Gradle build script, but for some reason, I can still see whatever exist in the resources directory to be copied into the built Jar. Which means for some reason the provided Gradle build is not working as expected.

apply plugin: 'distribution'

    distributions {
        main {
            baseName = "${project.name}"
            contents {
                into('/conf'){
                    from('src/main/resources')
                    exclude("application.yml")
                }
                into('/lib'){
                    from('build/libs')
                }
                into('/bin'){
                    from('../bin')
                }
            }
        }
    }


    processResources {
        # Not sure how I need to point to the resources, so I included both. However, none is working.
        exclude('resources/*')
        exclude('src/main/resources/*')
    }

    bootJar{
        # Not sure how I need to point to the resources, so I included both. However, none is working.
        exclude('resources/*')
        exclude('src/main/resources/*')    
    }

    distTar {
        dependsOn bootJar
    }

    tasks.withType(Tar) {
        compression = Compression.GZIP
        extension = "tar.gz"
    }

    configurations {
        customArch
    }

    artifacts {
        customArch file(distTar.archivePath)
    }
