Build for nightly/release

All required profiles are activated by the presence of a property named "release".

$ mvn clean install -Drelease

This will build, unit test, and package the whole project (all of the sub-modules). The artifact will be generated in: target

Build for CI/dev

The release builds will compile the source for production (meaning potential obfuscation and/or uglification). To build without that happening, just eliminate the release property.

$ mvn clean install

Build a subset of modules

TODO: list profiles

Unit tests

This will run all tests in the project (and sub-modules).

$ mvn test

If you want to remote debug a single java unit test (default port is 5005):

$ cd core
$ mvn test -Dtest=<<YourTest>> -Dmaven.surefire.debug

Integration tests In addition to the unit tests, there are integration tests in the core project.

$ mvn verify -DrunITs

To run a single integration test:

$ mvn verify -DrunITs -Dit.test=<<YourIT>>

To run a single integration test in debug mode (for remote debugging in an IDE) on the default port of 5005:

$ mvn verify -DrunITs -Dit.test=<<YourIT>> -Dmaven.failsafe.debug

IntelliJ

• Don't use IntelliJ's built-in maven. Make it use the same one you use from the commandline.
  • Project Preferences -> Build, Execution, Deployment -> Build Tools -> Maven ==> Maven home directory

1. Submit a pull request, referencing the relevant Jira case
2. Attach a Git patch file to the relevant Jira case

Use of the Pentaho checkstyle format (via mvn site and reviewing the report) and developing working Unit Tests helps to ensure that pull requests for bugs and improvements are processed quickly.
