The "moduleDevelopmentDeployment" page is intended for non-Java modules. As you've seen, we simplified the Java module build process recently to remove the need for a build.xml file in most cases. The main build should build and deploy your custom module, assuming its source directory is referenced in the "standard.modules" file (either explicitly or implicitly via wildcards). The main build will compile your Java files and JSPs, package all code and resources into a .module file, and deploy that module.
