Development

Setting up Intellij

Run ./gradlew idea to (re-) generate IntelliJ project and module files from the templates in .baseline. The generated project is pre-configured with Baseline code style settings and support for the CheckStyle-IDEA plugin.

Install Docker

Install and run Docker to support local containers.

Building

$ ./gradlew clean build

Testing

$ ./gradlew clean test

Formatting the code

Run ./gradlew format task which autoformats all Java files using Spotless.

Building deployment into local Maven cache

$ ./gradlew clean publishNebulaPublicationToMavenLocal

Releasing

We release by tagging which kicks off a CI build. The CI build will run tests, integration tests, static analysis, checkstyle, build, and then publish to the public Bintray repo to be synced into Maven Central.

Tag format:

vMajor.Minor.Patch

You can tag via git or through Github's Release UI.

Contributing

Mantis is interested in building the community. We welcome any forms of contributions through discussions on any of our mailing lists or through patches.

For more information on contribution, check out the contributions file here.
