How to create an Ant build file from Maven (pom.xml)?
In some cases, you may need to generate Ant build file (build.xml) for your project integration purpose. For example, the klockwork code analysis tool is required Ant file to perform the static code analysis processes for java project.
Maven Ant plugin
Maven comes with a handy Ant plugin to generate Ant build file from Maven pom.xml easily. Locate your pom.xml file, and issue the command : mvn ant:ant.
D:\Project_ABC>mvn ant:antOutput

Dear Mr MYKong
I saw your article converting Maven to Ant. I need the reverse of this. We have a project which uses Ant for build. I need the pom.xml for the same.
Can you please let me know how do I achieve this?
Any help is greatly appreciated.
Thanks
Abhijit
As far as I know that is impossible. Maven is a build system, Ant is a build tool. You can do the system->tool conversion, but not the other way around. Plus that Maven is more restrictive than Ant. If you want to convert an Ant script to Maven you’ll have to move the source code(java and resources) in certain folders, understand your dependencies and their scope, replace some Ant tasks with some Maven plugins, etc…
See answer from @Lucian Ochian.
Some draft ideas, convert the project into Maven structure, replace Ant functions with Maven plugins. Find the dependencies detail from http://search.maven.org/.
What could I do to change the local repository where ant makes maven download the artifacts??? I have the archives fetch.xml and get-m2.xml, and I have tried there, but it didn’t work because i didn’t do it properly, i suppose. Changing settings.xml in this case doesn’t work in any way.
Any idea??
Thank you!
hi, did you means Ant’s “Download dependencies target ” ? For example,
< get src="http://download.java.net/maven/2/junit/junit/4.5/junit-4.5.jar"
dest="${maven.repo.local}/junit/junit/4.5/junit-4.5.jar"
usetimestamp="false"
ignoreerrors="true" / >
Just change the “dest” to point to your destination folder.
