Re: Re: How to add a library to the classpath
I think as a user of maven the expected behavior (ask) is for the additionalClasspathElements to support a user.property which it doesn't currently. would be a good feature to add to maven exec plugin i believe. thanks again to all for the help.

Re: Re: How to add a library to the classpath
The way to separate multiple classpaths is to have multiple poms. You can make another child module (so that it inherits the base dependencies) and add the extra dependencies and the exec:java to THAT module.

Re: Re: How to add a library to the classpath
Hi All, Thanks for your help. To keep the discussion focused, the ask is how to add additional dependencies/jars to the classpath when running a program using mvn exec:java and from what i understand it is not possible. I am using mvn dependency:build-classpath to get the full CP and then augment it with additional jars and pass it to java (instead of maven exec:java) as workaround. but that is not the question being asked.

Re: Re: How to add a library to the classpath
Would using basic batch/shell specifying the dependencies with the Java classpath argument (without maven run) and the main runtime class be the alternative? Kind of a side question…when building with maven does it automate the addition dependencies within the META-INF/MANIFEST.MF (1) embedded within the jar?
