1) within the <ant:classpath> I need to somehow iterate through the list of
The short answer is to use ${maven.dependency.classpath}...see below:
From the aspectj-3.0 plugin:
<ant:iajc
fork="${maven.aspectj.fork}"
maxmem="${maven.aspectj.maxmem}"
incremental="${maven.aspectj.incremental}"
destDir="${maven.build.dest}"
sourceRootCopyFilter="${maven.aspectj.sourceRootCopyFilter}"
debug="${maven.aspectj.debug}"
emacssym="${maven.aspectj.emacssym}"
verbose="${maven.aspectj.verbose}">. . .
<ant:classpath>
<ant:path refid="maven.dependency.classpath"/>. . .
</ant:classpath>
.
.
.
</ant:iajc>
2) Secondly if the user specifies multiple classpath entries, like maven -DadditionalClasspath="/path/to/something.jar;/path/to/anotherjar.jar" is there someway for me to break that up into classpath entries?
Try this:
<util:tokenize
xmlns:util="jelly:util"
delim=";"
trim="true"
var="myPaths">
${additionalClasspath}
</util:tokenize><c:forEach xmlns:c="jelly:core" items="${myPaths}" var="path">
<ant:pathelement path="${path}"/>
</c:forEach>
3) and i lied one more question, to access VM variables do I simply do {variableName} from maven.xml?
What types of args are you trying to gain access to? You might be able to access them as system properties (for example: ${java.vm.version} or something)...beyond that, I'm not sure.

Subject: Re: A Goal that can execute a class' main method?
You might want to try Ant's <java> task for this. To use it, you should try embedding in a custom goal within your project's maven.xml file. I'll look something like this:
<project default="dbLoad" xmlns:ant="jelly:ant">
<goal name="dbLoad"> <ant:java [...options...] classname="com.myco.DbLoader"> <ant:arg value="${myData}"/>
<ant:classpath> <ant:pathelement path="${myPath}"/> </ant:classpath> </ant:java> </goal>
</project>
which you might then invoke using the following command:
maven -DmyData=/path/to/my/data -DmyPath=/path/to/my/classes dbLoad
You can find more info on the Ant java task at: http://ant.apache.org/manual/CoreTasks/java.html

Hi guys got a couple questions. Ive got a project that has a class that updates a database with information. What I was wondering is if it
would be
possible to make a maven goal that executes that class, thus making it
easy
on the end user (since the majority of the dependencies are listed
within
the dep list). The requirements are these: 1) I'd need to be able to pass in a java environment variable (from the command line) for where the datafiles are at to be ported into the db 2) I'd need to be able to add elements to the classpath of the class
that
will be executed (From the command line) in addition to the dependencies that are listed within maven
Is something like this possible? And if so, if you could point me in
the
direction on how to implement it I'd be greatly appreciative. Thanks, David
