Creating a Project with a Working Example of OpenL Maven Plugin Usage

OpenL Tablets has an archetype which can be used to create a simple OpenL Tablets rules project containing an example of OpenL Maven plugin usage.

OpenL rules project archetype

Current project is ready to deploy to OpenL Rule Services and shows an example of pure OpenL rules project with separated main and test modules.

  1. Execute the following command in the command line: 
      mvn archetype:generate
  2. Select the openl-project-archetype menu item then follow the wizard instructions to complete project creation.

    When the new Maven-based project is created, it appears in the file system:

    • The main OpenL project are located in src/main/openl directory.
    • The test OpenL project are located in src/test/openl directory.

    Directory structure is described here.

  3. To compile the project, in the command line, execute the following command from the root of the project folder: 
      mvn install

After that, the following objects can be found the target folder:

  • ZIP file with ${project.artifactId}-${project.version}.zip name.

    This archive contains only main project from src/main/openl directory and can be deployed to the OpenL Rules Services.
