Connector Template

Camunda Connector Template

Build

You can package the Connector by running the following command:

mvn clean package

This will create the following artifacts:

A thin JAR without dependencies.
An fat JAR containing all dependencies, potentially shaded to avoid classpath conflicts. This will not include the SDK artifacts since those are in scope provided and will be brought along by the respective Connector Runtime executing the Connector.

Shading dependencies

You can use the maven-shade-plugin defined in the Maven configuration to relocate common dependencies that are used in other Connectors and the Connector Runtime. This helps avoiding classpath conflicts when the Connector is executed.

Use the relocations configuration in the Maven Shade plugin to define the dependencies that should be shaded. The Maven Shade documentation provides more details on relocations.

Test with local runtime
