    <p>In my new project I am confronted with a complex infrastructure with several modules which have grown over the years in an unpleasant, uncontrolled way.</p> <p>To come to the point: The build process is the horror. There are over 40 different, complex Ant files, which are connected multiple times and the SOA framework also generates several dynamic Ant files. It took a few days to really understand all the dependencies and to finally build the whole project without any errors.</p> <p>My plan was or is to migrate the whole project from Ant to Maven, since new components are planned and I would like to avoid these problems in the future and well, because it is just horrible the way it is now ;-) </p> <p>Since I am new to the migration of bigger projects, I am a little bit confused about the best workflow. There are dozens of XML files and scripts involved, which are distributed in a non-Maven directory structure. Overall there are over 3000 files involved. One of the main problems is that I don't know if I really should try to migrate everything in the known Maven directory structure and therefore risk endless editing and refactoring of every single file. Or should I keep the folder structure as it is and bloat my pom.xml files and possibly run into problems with all the different involved plugins? Honestly, both ways don't sound quite constructive. </p> <p>Does it even make sense to migrate a project in this dimension to Maven? Especially when the SOA framework must use its own Ant files - therefore a combination of Ant and Maven would be necessary. What would be the best strategy to simplify this process?</p> <p>Thanks for all suggestions.</p>

    1. CO"Does it even make sense to migrate a project in this dimension to Maven?" Depends on what your goal is. In general I would tend to "no", specifically especially because of the horror of "dynamically generated Ant files". I would _never again_ start such a project using Ant - but converting an existing project is a completely different cup of tea.
