Question

Can Maven create two jars specified in one pom.xml: one jar with my app but without dependencies, and second jar ONLY with dependencies? I’d like to have two separate jars, but I want to run jar with my app and this app has to ‘see’ all dependencies in second jar. Everything I want to have in one eclipse project, only in result of one run of mvn:package I’d like to create separate jars…Is it possible? Now I use maven-jar-plugin to create jar with app, where I specify the classpath by add line in configuration of maven-jar-plugin:

<addClasspath>true</addClasspath>

Before I have used maven-assebly-plugin to create jar-with-dependencies, but now I have to create separate jar-s….

Thanks in advance, seishin

Here’s how I’d do it:

• use dependency:unpack to
  unpack all dependencies to a common
  folder,
• use the assembly plugin to create a
  new JAR from the unpacked dependencies
• provide a custom manifest to your project’s jar that
  links to the dependency jar
