## Composition by architecture modules

Each [architecture module and platform](platforms.md) can contribute code to any of the runtimes.
Not every module contributes to every runtime.

The core-runtime module defines each runtime:

- The target JVM for the runtime. Each runtime has its own JVM compatibility constraints.

    @Test
    void testGetModulePathAdjustment() throws IOException {
        Model moduleModel = new Model();

        MavenProject module = new MavenProject(moduleModel);
        module.setFile(new File("module-dir/pom.xml"));

        Model parentModel = new Model();
        parentModel.addModule("../module-dir");

        MavenProject parent = new MavenProject(parentModel);

// Module misc contains binaries that pertain to specific platforms
// (Android, iOS, and WebAssembly), as well as some miscellaneous
// tests and tools.
module misc

            // The formatting and structure are preserved automatically
            modulesElement.name(SUBPROJECTS);
            context.detail("Converted <modules> to <subprojects>");

            // Convert all module children to subproject
            var moduleElements = modulesElement.children(MODULE).toList();
            for (Element moduleElement : moduleElements) {
                moduleElement.name(SUBPROJECT);
            }

OkHttp URLConnection
====================

This module integrates OkHttp with `Authenticator` and `CookieHandler` from `java.net`.

This module is obsolete; prefer `okhttp-java-net-cookiejar`.
