I’ve recently implemented some new improvements to Minify Maven Plugin. Version 1.6 added support for Google Closure Compiler and version 1.7 offers several performance improvements and more detailed logs (e.g. compression benefits from minification). A complete list of changes can be found in the changelog file. For next releases I’m planning to add Source Maps support and improve the documentation.…Read more »
This bug is fixed on versions 2.2 or higher, and consequently, that workaround does not work anymore.

Reduce HTTP requests
Each of those are extra HTTP requests, and each unique request takes a relatively long time. The fewer requests to the server that the browser has to make, the faster the page will load.
There is an inherent overhead in each HTTP request. It takes substantially less time to serve one 60K file than it does three 20K files and a lot less than it does six 10K files.
Combine and minimize files
To keep the modularity that comes with splitting these files out by section (or business unit), keep them split in your development process, and combine them in your build process. A first Ant task will combine them and a second task will generate their minimized versions.
This technique has been successfully used in libraries such as jQuery, MooTools, Dojo, ExtJS, YUI, etc, allowing developers to better organize their code.

The Maven 2 Cobertura Plugin web site lacks information to successfully generate Cobertura reports. Worse, some of the usage examples are incorrect and don’t work. The most common problem when generating Cobertura reports is when the generated report shows 100% test coverage while in reality many of the classes don’t even have tests. The following example shows how to configure the reports so that it would reflect real test coverage and then check if the specified packages achieved the wanted test coverage:…Read more »
Problem - You want to use the last Hibernate 3 (Object to Relational Mapping Solution) with a code generation tool that automatically generates your Hibernate descriptor files, and build your project with an advanced build tool like Maven2.
Solution - Use maven2-xdoclet2-plugin.
Maven is a popular open source build tool for enterprise Java projects; it can manage a project’s build, reporting and documentation from a central piece of information (POM file).
XDoclet is an open source code generation engine with the goal of continuous integration. It enables Attribute-Oriented Programming for java. It uses custom JavaDoc-like tags to generate external resource files to support the main Java classes. XDoclet has mainly been used for the auto-generation of EJB descriptors (and related J2EE container technologies). XDoclet2 is a rewrite of the XDoclet engine. It allows you to use Hibernate 3 features, Java5 language features in your model POJOs, and has substantially better error reporting than XDoclet.
