Including Maven Dependencies in Build
I have a working ant build script but I changed my application to use
some maven dependencies. I am trying to include those dependencies into
that build script. I found this article for doing that:
https://stackoverflow.com/questions/7335819/ant-eclipse-complains-about-artifactdependencies
I know this article is old but I cannot find anything more recent that
is the equivalent. If anyone has anything I would certainly be
interested. Anyway as result I came up with this build.xml
<?xml version="1.0" encoding="UTF-8"?>
<project name="KCBSEvents" default="jar" basedir="."

<property name="member.name" value="" />
<path id="maven-ant-tasks.classpath"

When I run ant I get a successful build. However, when I try to run the
resulting jar file I get a traceback. The trackback seems to imply that
the maven dependencies were not pulled into the jar. Am I missing
something in the build that ties the dependencies to the jar? Can
someone help me debug this? TIA.
FWIW here is the resulting output from the build:

Although no one was able to ultimately help me with this problem I did
finally get it to work. It took a lot of digging and trying a lot of
different suggested solutions before I found one that actually worked.
To close out this thread for the archives, here is what I discovered:
It seems that 'ant' is not able to figure out how to handle the maven
remote repositories or maven jar files, at least in any of the solutions
I tried. I finally found that if I downloaded the maven jars manually
and put them in the normal maven library (.m2/repository) I could then
use the zipfileset directives to get them included. Although the library
itself is really arbitrary. Here is my final build xml file, the bolded
text is all I needed to change:

I found another article that suggested adding a classpath. I did notice
that "compile.classpath" in my original xml was not set. I created a new
"build.classpath" and added a "lib" directory to my build directory.
Although I am getting the same results perhaps I am a bit closer, at
least it makes logical sense to me now. Here is my latest xml:

Somehow I am still not able to get ant to pull in the maven dependencies.

Hi Jaikiran,
Thanks for the reply. I thought it must have been some thing like that.
After reading your link and as a maven noob and not much better with
ant, I see I have to copy those dependencies. But it is not clear where
they need to be copied to. The example shows "lib" but I don't see how
javac knows to look there unless it is by default. My build directory is
a local git repository so the structure is "bin" and "src" in that
directory. There is no "lib" at the present time. That is also were I
have the build xml file for ant along with some files for obtaining some
information during the ant build. The output file for the jar is in a
directory in "/tmp" which is later copied to its final location.

I don't see this fileset being used in the rest of the target(s) which
generate your jar file. Maybe you missed using it to copy over the

for an example on how you could use it.
