Building from source

JMXFetch uses Maven for its build system.

In order to generate the jar artifact, simply run the mvn clean compile assembly:single command in the cloned directory.

The distribution will be created under target/.

Once the jar is created, you can update the one in the Datadog Agent repo.

Coding standards

JMXFetch uses Checkstyle with Google Java Style to enforce coding standards.

To perform a Checkstyle analysis and outputs violations, run:

mvn checkstyle::check

Checkstyle analysis is automatically executed prior to compiling the code, testing.

Generated code

JMXFetch uses Lombok to modify classes and generate additional code at runtime. You may need to enable annotation processors to compile in your IDE.
