A Goal that can execute a class' main method?
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

Posted by John Casey <jd...@commonjava.org>.
If you don't use fork, you've got to deal with the fact that maven has a
copy of Xerces in its endorsed directory
${maven.home}/lib/endorsed...this could cause classloader issues, I'd
imagine.
Anyway, I think fork="true" is usually a good idea regardless.

Re: A Goal that can execute a class' main method?
Posted by David Erickson <de...@cmcflex.com>.
Ok I got it to work by having ant spawn my class in a different JVM.. using
fork="true" spawn="true". I think there some 'issues' with running
something that needs xml access from inprocess with maven.. i cant remember
the circumstances I ran into last time but it was similar and drove me
nuts.. fortunaetly this works great.
Thanks everyone for the help!!

Re: A Goal that can execute a class' main method?
Posted by David Erickson <de...@cmcflex.com>.
Thanks got everything working as its supposed to I *think* except I am
having major XML issues.. it seems like I ran into something similar like
this previously, I wasnt sure if its because maven has xml stuff loaded or
what.. but heres the errors:
[echo] C:\projects\NADA/target/classes/NADA-.1.jar

and yet within my project I have:

Any ideas?

No single page, I don't think...(maybe I'm not up to date on that,
though). You might have some luck here:

Re: A Goal that can execute a class' main method?
Posted by David Erickson <de...@cmcflex.com>.
Thanks a ton to John and Carlos you guys have been extremely helpful.
Couple more Q's
1) Is there a webpage somewhere that lists all the variables that maven
makes available that can be accessed in maven.xml? I hate having to ask
stupid questions about that even though I cant find a listing =/
2) Here is what I've got in there now:
<goal name="updateDatabase">
<attainGoal name="build:start"/>
<attainGoal name="java:prepare-filesystem"/>
<attainGoal name="java:compile"/>
<attainGoal name="java:jar-resources"/>
<ant:java classname="com.cmcflex.nada.util.UpdateDb">
<ant:classpath>
<ant:path refid="maven.dependency.classpath"/>
<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="${path}"/>
</c:forEach>
</ant:classpath>
<ant:jvmarg value="-DnadaPath=${nadaPath}"/>
</ant:java>
</goal>
However I forgot that the actual files generated by the project arent on the
dependency list, is there a variable that holds the path to the target jar
file that is generated? I need it for my classpath.
Also this line I used: <ant:jvmarg value="-DnadaPath=${nadaPath}"/>
is that gonna fly? basically I just need to pass a variable from the
current jvm system property into the spawned version from ant's java?
Thanks,
David

The short answer is to use ${maven.dependency.classpath}...see below:
From the aspectj-3.0 plugin:
<ant:iajc

Try this:
<util:tokenize

trim="true"

${additionalClasspath}
</util:tokenize>
<c:forEach xmlns:c="jelly:core" items="${myPaths}" var="path">

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.

Re: A Goal that can execute a class' main method?
Posted by David Erickson <de...@cmcflex.com>.
John,
Thanks that helps tremendously, my other 2 remaining questions would be
1) within the <ant:classpath> I need to somehow iterate through the list of
project dependencies, something like:
<ant:classpath>
<while mydeps.hasmore>
<ant:classpath path=mydep>
</while>
</ant:classpath>
Is there someway to do something similar to this?
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?
3) and i lied one more question, to access VM variables do I simply do
{variableName} from maven.xml?
Thanks,
David

Re: A Goal that can execute a class' main method?
Posted by John Casey <jd...@commonjava.org>.
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
HTH,
john

<maven:get var="" property="" default""/>
For concrete syntax you can check the announcement plugin "plugin.jelly" for
example

You can check the java plugin
<ant:classpath>
<ant:path refid="maven.dependency.classpath"/>
<ant:pathelement path="other paths"/>
</ant:classpath>

Re: A Goal that can execute a class' main method?
Posted by David Erickson <de...@cmcflex.com>.
1) ok so when I call maven from the command line like "maven mygoal" how do
I specify these things? like "maven mygoal -Dmyoption=myvalue" ?
2) how can I get a handle on that variable from within my goal scripts?
3) how can I get a handle on the classpath from the dependencies in my
project.xml?
Thanks,
David

Hi,
You can implement it with ant tasks (<java> I think) in maven.xml
1) -Dvar=value
2) <java> can have nested classpath
