Relationsship "pom.xml" and "build.xml" from Ant
Sorry for this Maven newbie question but I want to clarify the relationsship
between pom.xml and Ant's build.xml.
Are the following statements correct?
pom.xml is solely Maven related
build.xml is solely Ant related
Both do not (never) depend on each other (are e.g. included).
So if I get a project which contains a pom.xml and a build.xml then the
developer offers to use
either Ant or Maven. If I select Maven then I can delete build.xml. If I
select Ant then I can delete pom.xml without harm.
Is there a way to convert a build.xml into a pom.xml and vice versa?
Ok in case of pom.xml -> build.xml I would loose some functionality but this
should not be the question at this point.
Is there such a converter?
Thank you
Ben

It is possible to build Maven projects from Ant, and vice versa.

Generally yes, but not always.

No.

Also, if an ant build uses the Ant Maven plugin, for example to access a dependency, the plugin will read the pom file.

maven/POMs can make use of ant build scripts, so be wary of this
scenario; it is fairly common to use ant via maven

also a project can have various components that build in different
ways, so again, I wouldn't make the above assumption
there is no way to convert an ant build script into a maven POM,
because ant scripts don't have any kind of enforced convention; it
would be impossible to write such a converter

Re: Relationsship "pom.xml" and "build.xml" from Ant
Posted by Shan Syed <sh...@gmail.com>.
you can reference an external build file within the ant-run plugin, so
something like:
..
<ant antfile="${basedir}/build.xml">
<target name="test"/>
</ant>
..
taken from the second example
http://maven.apache.org/plugins/maven-antrun-plugin/examples/classpaths.html
chances are that in your case:
-the two separate builds are required to build the overall project,
and maybe they didn't have time to migrate certain parts of the ant
build to maven
or
-the maven build references the ant one and invokes it
and/or
-the ant is used for something other than an actual build (ant is
still a great tool for other stuff)

Ask the person who built the code/gave you the project, or check for
project documentation.

Thank you. But how do I find out if a pom.xml uses a build.xml in the same
directory?
Do I have to search for a
<include>build.xml</include>
or a
<call>build.xml</call>
statement in pom.xml?
