We use the Mattermost Plugin for Jenkins. When the Pipelinebuild has finished in Jenkins it shall send a message to the hook in mattermost reporting the status of the build. Can I assign an avatar on per project basis like
failure {
mattermostSend color: 'danger', message: 'API-Tests have failed', channel: 'api-tests', avatar: 'http://someadress.com/avatar.jpg'
}
?
What format must the icon have? size and extension?
