NMaven

NMaven is a fantastic piece of software that provides Maven 2.x plugins that can support the building of .NET applications. Its framework is specifically designed to provide the correct .NET compiler based on various criteria such as vendor, language, and operating system.

What particularly sets this software apart is how easy it is to add additional compiler support. This is achieved by implementing the NetCompiler interface and providing a compiler-plugins.xml file in the project directory. This means that the software can be tailored to suit a specific project's needs, providing an extremely flexible approach.

One of the other great features of NMaven is that it uses Maven's plugin architecture for the build lifecycle. The fact that it leverages Maven means that developers can rely on the larger Maven build-framework, which is widely used and very robust.

Overall, NMaven is a small, compiler-plugin-framework that sits on top of the larger Maven build-framework. It's well-designed and truly delivers on its promise of supporting the building of .NET applications with ease, flexibility, and reliability.
