Mattermost

This announcer has been deprecated in v1.4.0 and will be removed in v2.0.0. Use Webhooks instead as shown here.

Posts a message to a Mattermost room. You must create a custom webhook for this announcer to work.

Webhooks are not protected, anyone with access to the webhook URI can send messages to the target room. Prefer setting the JRELEASER_MATTERMOST_WEBHOOK environment variable over explicitly setting a value in the configuration DSL.
