Subject [jira] [Updated] (MJAR-198) jar:jar without classifier replaces default jar
Date Tue, 20 Nov 2018 21:12:00 GMT

     [ https://issues.apache.org/jira/browse/MJAR-198?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Hervé Boutemy updated MJAR-198:
-------------------------------
    Description: 
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|https://maven.apache.org/plugins/maven-jar-plugin/jar-mojo.html#classifier]
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.
