Re: Ant Project Convert To Maven
Posted by Hervé BOUTEMY <he...@free.fr>.
the approach i used in a company was in 2 steps:
1. continue to build with Ant, but with Maven Ant Tasks for dependency
management
2. use Maven to try to build, in parallel with Ant, to check if you get the
same result. A first result here was to get a reporting site working, even if
the artifact built by Maven wasn't completely right

Ron, Russ and myself have experience in both build environments
Ant <pathelement> becomes Maven <dependency> in <dependencies>
Ant Taskdef becomes Maven Mojo which has multiple @goals which you later bind to a maven lifecycle phase
Ant <target> becomes <plugin> in <build><plugins>
Ron is right ...alot of people fight with maven because they dont understand the importance of version specific artifacts deploying in execution environments
having inconsistent versions of libraries leads to runtime exceptions
if you're lucky you'll get a ClassNotFoundException or ClassCastException
if you're not lucky you'll get a Stacktrace which you will have to comb thru to get to the problem
which is the reason is why every build engineer will learn to become a 'maven maven'
start here
http://maven.apache.org/
maven founder has his own website with useful examples and tutorials at
http://www.sonatype.org/
Thanks and Regards,
Martin

Re: Ant Project Convert To Maven

Start by scanning a few of the free books and articles about Maven.
This will give you a good overview of the Maven way of looking at things.
I use Eclipse/STS from SpringSource http://www.springsource.org/sts.
It is a very good Maven IDE and comes ready to go with a single download.
I am sure that you will find a lot of Netbeans users here who are also
happy.
Maven is driven by convention and is very set in its ways.
Forget anything that you know about Ant and be prepared to completely
rethink your build processes.
If you try to make Maven into an advanced Ant build, you will have a big
fight on your hands until you change your mind.
Maven will not change its mind about building software no matter how
hard you try to bend it to your will.
Start out with a simple Maven project model and get it working before
you try to optimize your process.
A lot of people get into trouble by trying to implement advanced
automation before they get their project to build as a simple Maven project.
In the end, you will have a much more repeatable build process that can
be shared with your team without having to explain the steps.
It is pretty easy and safe to pick up someone's maven project and
rebuild it without having to read their POM files.

Hi Raja,
Having done this several times, with projects of varying complexity, I am sorry to say that AFAIK there is no automated way to do it. The problem is that ant is a very free form scripting language that allows you to describe builds - but ant writers cannot be guaranteed to do everything the same way.
Ant does not require any particular conventions for organizing source trees, invocation of external programs to process code, or even require a single source tree to map to a single artifact. Bottom line is, you're going to have to do the change manually. Now if your project is simple, turning it into a maven build is trivial. But I've spent a couple of works converting one project, and am in the middle of a massive one with a couple of hundred ant scripts and a few dozen special processing steps, that I expect to take several months to convert.
Do you have any specific questions about converting your build? How complex is it?

Re: Ant Project Convert To Maven

Please have a look at the freely available books at
http://maven.apache.org/articles.html
I'm sure one of these shows you a step by step approach for converting to Maven.
Something along the lines of
1) Write a basic pom that does nothing but invoke ant
2) Start removing bits from Ant and replacing them with the Maven equivalent
...
N) Done
