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
