Have you look at <DependencyManagement> node?
Look at
http://jira.codehaus.org/browse/MNG-743 and download the
sample-m2-project.jar from the attachement.
I.E.
<dependencyManagement>
<dependencies>
<dependency>
<groupId>net.bzdyl.demo</groupId>
<artifactId>demo-par</artifactId>
<version>1.0</version>
</dependency>
</dependencyManagement>
Note: by default maven-jar-plugins hardcoded the .jar file name
extension. I don't think it's hard to patch the
maven-components/maven-plugins/maven-jar-plugin/src/main/java/org/apache/maven/plugin/jar/JarMojo.java
file to suport this feature.
Regards,
Edward Yakop
Note:
The attached file is a sample implementation of JarMojo.
To use:
0. Check out maven-source tree
svn co https://svn.apache.org/repos/asf/maven/components/trunk
maven-components
or follow
http://maven.apache.org/maven2/developers/building.html
1. Update JarMojo.java
Replace the JarMojo.java inside
maven-components/maven-plugins/maven-jar-plugin/src/main/java/org/apache/maven/plugin/jar
and
cd maven-components/maven-plugins/maven-jar-plugin ; m2 install
2. Replace pom.xml of demo-par dir.
<project xmlns="http://maven.apache.org/POM/4.0.0";
