There is a .travis.yml template in this project which is prepared to automatically
deploy the plugin artifacts (JAR, DEB, RPM) to GitHub releases.
You just have to add your encrypted GitHub access token to the .travis.yml.
The token can be generated in your GitHub personal access token settings.
Before Travis CI works, you have to enable it. Install the Travis CI command line
application and execute travis enable.
To encrypt your GitHub access token you can use travis encrypt.
Alternatively you can use travis setup -f releases to automatically create a GitHub
access token and add it to the .travis.yml file. Attention: doing this
will replace some parts of the .travis.yml file and you have to restore previous
settings.
