#pentaho-metaverse

This project defines implementations and interfaces for use with the Pentaho Metaverse, which provides the following capabilities:

• Data Lineage
• Impact Analysis
• Metadata auditing/governance
• Provenance diagnostics (missing links, references, files, etc.)

How to build this project

This is a maven-based project so you must have it available on your system.

Typical build. This will compile the code, run the unit tests, and assemble a Pentaho platform-plugin in the target folder.

mvn install

Compile only.

mvn compile

Run the unit tests.

mvn test

Run the integration tests.

mvn integration-test

Run the unit tests with code coverage. This will output an html report here: target/site/cobertura/index.html

mvn clean compile test-compile cobertura:cobertura

Run checkstyle against the code. This will output an html report here: target/site/checkstyle.html

mvn checkstyle:checkstyle

Maven command line switches to get familiar with

• -o, --offline Work offline
• -D, --define Defines a system property. One particularly useage of this iw when you don't want the unit tests to run. To do that, just define the skipTests property

mvn install -DskipTests

• -U, --update-snapshots Forces an update for releases and snapshots from remote repository

Other build tips

The default profile when building is "production". When that profile is active, the install goal will also obfuscate the artifact. To force this to the development profile where obfuscation is not run, you have 3 options...

• set the active profile on the commandline

mvn install -P development
mvn install -P production

• activate the profile with the "env" property setting

mvn install -Denv=dev
mvn install -Denv=prod

• activate the profile in your /.m2/settings.xml file using the env property

<settings xmlns="http://maven.apache.org/SETTINGS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd">

  <profiles>
    <profile>
      <activation>
        <activeByDefault>true</activeByDefault>
      </activation>

      <properties>
        <env>dev</env>
      </properties>
    </profile>
  </profiles>
</settings>
