Find centralized, trusted content and collaborate around the technologies you use most. Connect and share knowledge within a single location that is structured and easy to search. I know that this is a complicated question, but I would like know which one is better in the case of a system that it's already in production, with a lot of bugs and really bad design at all. A really mess. I needed to adjust the folder structure, separate a terrible framework made at the company from the project it was converted into a jar lib , fix a lot of details that broke the project all the time, configure the POM.
Well, it was a really hell. I went crazy during this task and the question that followed me all the time was "And if I was converting it to Ivy?
Would be easier? I never worked with Ivy, but as I know it work with Ant and it's easier then Maven to adapt the project. On the other hand, Maven it's much more used allover the word Am I wrong? The key information:. First, the most important difference is that they aren't at all the same kind of tools. But this goes beyond the scope of this page which concentrates on dependency management only. Ivy adds dependency management functionality to Ant, so really, the question in terms of what build system you use is either:.
If your build is already using Ant, Ivy will be an easier transition since your build scripts don't need to be ported to a different build system. If you decide to transition to Maven it will require more effort, because you need to rewrite your build scripts and Mavenize everything as well as configure your dependency management.
Examples An example of what to put in your pom. About An Ivy to Maven bridge for dependencies. Resources Readme. Releases No releases published. Packages 0 No packages published. You signed in with another tab or window. For example, the configuration test would contain all artifacts used for testing. Appendix A. What you need to know about Ivy. Module identification. With Apache Maven, it's a bit difficult to clearly know what can be considered as dependency management documentation, but we didn't managed to find much: some small introductory guides, short entries in the pom reference guide, and not really much more.
Even in the maven book you can get for free on mergere website , the insight about dependency management is still light in our point of view.
Conflict management Conflict management are an important part of dependency management, cause when dealing with transitive dependencies you often have to face conflicts. In this area, Apache Ivy let you do whatever you want: use one conflict manager in one module, another one elsewhere, decide which revision you will get, You can even plug your own conflict manager if you need to.
With Apache Maven, conflict management is quite simple: the principle is to get the nearest definition. So if your module depends on foo 1.
It may be ok in some cases, it may not in others Flexibility In Apache Ivy many things can be configured , and many others can be plugged in : dependency resolvers, conflict manager, module descriptor parser, latest revision strategy, Apache Maven also offers repository pluggability, but not much more as far as we know.
Moreover, repository configuration is much less flexible than with Apache Ivy: no repository chaining, no way to split metadata and artifacts in multiple repositories,
