Hi,

I use whitesource plugin within scripted Pipelines at groovy:

def scanStep() {
    script.echo " *** start WhiteSource scan ***"
    script.echo "productName: ${this.productName}"
   script.echo "productVersion: ${this.productVersion}"
   script.echo "includes: ${this.includes}"
   script.echo "excluded: ${this.excludes}"

   script.whitesource jobApiToken: this.jobApiToken,
                 jobCheckPolicies: 'global', jobForceUpdate: 'global',
                 libIncludes: this.includes,
                 libExcludes: this.excludes,
                 product: this.productName,
                 productVersion: this.productVersion
     script.echo "*** stop WhiteSource scan ***"
}

Execution Console output:
07:31:52 *** start WhiteSource scan **[Pipeline] echo*07:31:52 productName: node-js-sample[Pipeline] echo*07:31:52* productVersion: 1.1.1-devel[Pipeline] echo*07:31:52* includes: */.js[Pipeline] echo*07:31:52* excluded: [Pipeline] whitesource*07:31:52* Updating White Source.07:31:52 Collecting OSS usage information*07:31:52* Starting generic job on /myworkspace*07:31:53* Job finished.07:31:53 WhiteSource Service URL:07:31:53 Checking policies*07:31:52* Scanning folder ojects_MD_jpl-sample-npm_develop*07:31:53* Found 322 dependencies matching include / exclude pattern in folder.07:32:55 Generating policy check report*07:32:55* Some dependencies violate open source policies, however all were force updated to organization inventory.07:32:55 Sending to White Source*07:32:57* WhiteSource update results: 07:32:57 WhiteSource organization: *****07:32:57 0 Newly created projects:07:32:57 07:32:57 1 existing projects were updated:07:32:57 develop - 1.1.1-devel*07:32:57* WhiteSource Support Token: ****

It looks like product parameter to plugin is ignored and plugin used branch name or folder name instead. It should be product name as provided by product parameter.
It behaves the same for npm and maven projects and WhiteSource reports at SaaS service are not categorized correctly.
