Controlling maven final name of jar artifact
I'm trying to define a property in our super pom which will be used by all child projects as the destination of the generated artifact.
For this I was thinking about using project/build/finalName yet this does not seem work, even for simple poms:
Command
mvn archetype:create
-DarchetypeGroupId=org.apache.maven.archetypes
-DgroupId=com.mycompany.app
-DartifactId=my-app
POM
maxim@maxim-desktop:/tmp/mvn_test$ cat my-app/pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

I would expect the string "testing" would appear somewhere in the generated artifact name.
Am I misunderstanding the purpose of "finalName" ?
Thank you, Maxim.
You set the finalName property in the plugin configuration section:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<finalName>myJar</finalName>
</configuration>
</plugin>
As indicated in the official documentation.
Update:
For Maven >= 3
Based on Matthew's comment you can now do it like this:
<packaging>jar</packaging>
<build>
<finalName>WhatEverYouLikey</finalName>
</build>
See bug report/documentation.

try this...
pom.xml
<groupId>org.opensource</groupId>

Commnad mvn clean install

Reference
All of the provided answers are more complicated than necessary. Assuming you are building a jar file, all you need to do is add a <jar.finalName> tag to your <properties> section:
<properties>
<jar.finalName>${project.name}</jar.finalName>
</properties>
This will generate a jar:
project/target/${project.name}.jar
This is in the documentation - note the User Property :
finalName:
Name of the generated JAR.
Type: java.lang.String
Required: No
User Property: jar.finalName
Default: ${project.build.finalName}
Command Line Usage
You should also be able to use this option on the command line with:
mvn -Djar.finalName=myCustomName ...
You should get myCustomName.jar, although I haven't tested this.
