Define 'jenkinsUrl', 'jenkinsUser' and 'jenkinsApiToken' gradle properies. Api token can be added on https://{jenkinsUrl}/user/{jenkinsUrl}/configure url.
Execute 'gradle syncJenkinsConfig' command in project folder.
If automatic download of Jenkins installed plugins failed due to some issues and bugs your can open the https://jenkins-aws.indexdata.com/pluginManager/api/json?depth=2 url, save the content to "jenkinsResources/plugins.json" file and rerun "gradle syncJenkinsConfig" and at this time all Jenkins dependencies will be added to classpath.
