Elias Elmqvist Wulcan commented on MJAR-198:
--------------------------------------------
That is very nice but the artifact is still attached and installed which is
opposite of what the documentation says.
{quote}
classifier
String
Classifier to add to the artifact generated. If given, the artifact will be
attached. _If this is not given,it will merely be written to the output
directory according to the finalName._
{quote}
A project using jar packaging and also building some intermediary jar files,
will have its default jar overwritten by one of the intermediary jar files on
install. If the intermediary jars are strange in some way, for example with
special class path prefixes or special excludes, this behavior will cause
depending projects to fail.
> jar:jar without classifier replaces default jar

> Key: MJAR-198
> URL: https://issues.apache.org/jira/browse/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
> Priority: Minor
> Labels: newbie
> 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.
