[MJAR-198] jar:jar without classifier replaces default jar
The maven-jar-plugin now will fail if you try to replace the original
artifact in case of a second execution without defining a classifier.
Improved documentation about the classifier. (khmarbaise:

> Key: MJAR-198

> Project: Maven JAR Plugin
> Issue Type: Bug
> Affects Versions: 2.3.1, 2.3.2, 2.4, 2.5, 2.6
> Environment: Windows 8.1 Pro
> JDK 1.8 45
> Maven 3.2.5
> Reporter: Elias Elmqvist Wulcan
> Assignee: Karl Heinz Marbaise
> Priority: Minor
> Labels: newbie
> Fix For: 3.0.0

> Attachments: 0.tar, mvn.install.debug.txt

>
> If I add an execution of jar:jar in a project of packaging jar and do not
> configure a classifier for the additional jar, the additional jar will be
> installed instead of the default jar.
> Omitting a classifier in the configuration for the goal jar:jar is documented
> to have the effect that the jar will not be attached and this is the behavior
> that I want. Instead, the jar is attached and replaces the default jar.
> AbstractJarMojo.java:254 checks nullness of classifier to decide whether to
> attach or not. JarMojo.java:51 declares a default value the empty string for
> classifier. Maybe the combination of these lines cause the bug.
