A simple Java CLI tool to export the messages from a Rocket Chat server. It currently supports groups, channels and direct message export. You can either choose a single conversation or export all in a batch. As export format this tool only supports the Slack CSV output format as of now, but adding new output format is quite easy (check out the ExportFormat interface).
This tool uses the RocketChat API and is useful for situations where the user does not have administrative access to the server.
Provide the tool with your host URL, output file and username.
java -jar .\rocketchat-exporter.jar --host "http://my-rocket-chat.com" -o "./out" -u "fname.lastname@mail.com"
After that the password will be prompted. The tool will print all available channels. Choose one and the resulting export will be written to the provided file. Example output:
Please enter your RocketChat password: ************
Authentication successful (fname.lastname).

Use the Maven wrapper to create a jar including all dependencies
mvnw clean install
This project uses my common-parent which centralized a lot of
the plugin versions as well as providing the checkstyle config rules. Specifically they are maintained
in checkstyle-config. Locally the files will be copied after
you mvnw install into your target folder and is called
target/checkstyle-checker.xml. So if you use a plugin for your IDE, use this file as your local configuration.
