Maven and special building behaviour
Hello,
perhaps you can help me.
I got a WAR (web archive) which is built with maven.
It works perfectly.
mvn clean package install
But from now on, I need to create and additional special version of this war
from the same code base. In this special version, some modification will be done:
- some classes are removed from the war (indeed controller classes)
- a configuration file is changed
the special version is a limited version of the normal version.
It should be deployed with a special tag, e.g.
MyWar - Version 1.0.0 - specialEdition.
Is this possible with maven?
If so, how?
Branching in svn is overwhelming
Thanks you

Maven can do damn near anything. That does not mean that it should.
The first advice was right.
Split MyJar to remove the classes to make a MyJar-common of all the
classes that you always want.
Make MyJar-common a dependency of a smaller MyJar that only has the 3
classes.
Make your other jars depend on the either MyJar-common (war) of the new
MyJar which has all the classes(mostly by dependency)
That is the "Maven Way". You and Maven will remain friends if you do this.
It may also be easier to maintain as your project grows since it starts
you down the road to smaller more functionally-oriented projects that
are more stable in the same way that functional design at the code level
helps make software more robust and reduces the scope of maintenance
activity.
Other ways to make your end-result happen will piss-off Maven and get
you into a war of attrition which you will eventually give up on and go
back to the advice that you got, in order to restore your relationship
with Maven.
"Resistance is futile".

Thank you, but maybe you got it wrong.
My Project is already separated in the following way
MyJar.jar
MyWar.war
MyEear.ear
During the build of the war, some 3 class files should be removed, like this
del src/main/java/.../controller/SpecialAdmin1Controller.java
del src/main/java/.../controller/SpecialAdmin2Controller.java
del src/main/java/.../controller/SpecialAdmin3Controller.java
Can this done with maven without separating?

Probably not, it should be deployed with a specific name that differs
it from the normal artifact. Not a special tag.

Yes

You divide your project in different modules. Everything common should
be in a common module, anything specific should be in a specific
module. Typically one module per artifact.
The common module should create a jar that the specific modules depends on.
These specific modules should all depend om the common module, add
it's specific difference and finally produce a war as deployable
artifact.
This would be the Maven way. Common things in one module, specific
things in specific modules.

Branching my be the root of all evil. Avoid if possible.
