Managing Maven / JAR Dependencies

This skill explains how to add, update, and remove Maven/JAR dependencies in a Mendix module using MDL. These are the dependencies declared in Studio Pro's Module Settings → Java dependencies tab, stored as Projects$JarDependency entries inside the module's Projects$ModuleSettings unit.

When to Use This Skill

• Adding a new external library for a Java action (Jackson, Apache HTTP client, etc.)
• Updating a library version across modules
• Disabling a dependency without removing it (included = false)
• Auditing which modules have JAR dependencies

If you only need to copy JARs into vendorlib/ for a local build (without registering them in module settings), that is a different operation and does NOT require MDL.

Listing Dependencies

-- All modules
LIST JAR DEPENDENCIES;

-- Single module
LIST JAR DEPENDENCIES IN MyModule;

Output columns: module, group, artifact, version, included.

Describing a Dependency

DESCRIBE JAR DEPENDENCY MyModule 'com.fasterxml.jackson.core:jackson-databind';

Outputs a re-executable ALTER MODULE ... ADD JAR DEPENDENCY (...) block.

Adding a Dependency

mdl 1;
ALTER MODULE MyModule
  ADD JAR DEPENDENCY (
    group    = 'com.fasterxml.jackson.core',
    artifact = 'jackson-databind',
    version  = '2.21.2',
    included = true,
  );
