Integrating rules as a Maven project in an IDE

Develop business rules as a Maven project – auto-generated pom.xml, development mode and Java 8 SDK.

From Nuclos 4.30, business rules can conveniently be integrated as a Maven project in an IDE. Nuclos automatically generates a pom.xml under <NUCLOS-HOME>/data/codegenerator.

Prerequisites

the server runs locally (the codegenerator directory is on the developer machine) – or CODEGENERATOR_POM_LIBDIR, …_AXIS_LIBDIR and …_EXTENSION_LIBDIR are configured;
the server runs in development mode;
an IDE with Maven support (example: IntelliJ IDEA Community Edition);
a Java 8 JDK (ideally the same as the server).

Run Nuclos with normal user rights (not as a service) to avoid access problems. If that does not help, deleting the codegenerator directory (recreated on server start) may help.

Steps

Create a new project and select the codegenerator directory (IntelliJ recognizes it as a Maven project).
Enable „import Maven projects automatically“.
Keep the server running in the background – only then are all libraries found.
Add the missing SDK (Java 8) via the plus button and finish the wizard.

Templates: pom.xml without extension and pom.xml with extension.
