Pentaho Data Integration

Pentaho Data Integration ( ETL ) a.k.a Kettle

Project Structure assemblies: Project distribution archive is produced under this module core: Core implementation dbdialog: Database dialog ui: User interface engine: PDI engine engine-ext: PDI engine extensions plugins: PDI core plugins integration: Integration tests How to build

Pentaho Data Integration uses the Maven framework.

Pre-requisites for building the project: Maven, version 3+ Java JDK 11 This settings.xml in your /.m2 directory Building it

This is a Maven project, and to build it use the following command:

$ mvn clean install

Optionally you can specify -Drelease to trigger obfuscation and/or uglification (as needed)

Optionally you can specify -Dmaven.test.skip=true to skip the tests (even though you shouldn't as you know)

The build result will be a Pentaho package located in target.

Packaging / Distributing it

Packages can be built by using the following command:

$ mvn clean package

The packaged results will be in the target/ sub-folders of assemblies/*.

For example, a distribution of the Desktop Client (CE) can then be found in: assemblies/client/target/pdi-ce-*-SNAPSHOT.zip.

Running the tests

Unit tests

This will run all unit tests in the project (and sub-modules). To run integration tests as well, see Integration Tests below.

$ mvn test

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

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

Integration tests

In addition to the unit tests, there are integration tests that test cross-module operation. This will run the integration tests.

$ mvn verify -DrunITs

To run a single integration test:

$ mvn verify -DrunITs -Dit.test=

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= -Dmaven.failsafe.debug

To skip test

$ mvn clean install -DskipTests

To get log as text file

$ mvn clean install test >log.txt

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 Contributing Submit a pull request, referencing the relevant Jira case Attach a Git patch file to the relevant Jira case

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

When writing unit tests, you have at your disposal a couple of ClassRules that can be used to maintain a healthy test environment. Use RestorePDIEnvironment and RestorePDIEngineEnvironment for core and engine tests respectively.

pex.:

public class MyTest { @ClassRule public static RestorePDIEnvironment env = new RestorePDIEnvironment(); #setUp()... @Test public void testSomething() { assertTrue( myMethod() ); } } Asking for help
