Almost newbie: Q: How get rid of unused jars?

[Alec Leamas]

Last package in this bunch...

Package builds a number of jars in a hierarchical build. One of these is 
really what I think is called an ũber-jar, and that's the only one I 
want to package.

However, since the %mvn_build/%mvn_install  discovers also the other 
jars, they also get installed. I could of course just remove them after 
%mvn_install, but they are also part of the metadata, so...

My question: is there any sane way to remove one or more jars from the 
installed set? Something like %mvn_remove_artifact?

Cheers!

Why would you want to? What I'd other developers want to depend on those
other artifacts? Is there a problem with keeping them?

I just don't want to expose this internal structure. After all, isn't 
this the very idea with what seemingly is called an über-jar?

How is the package distributed upstream? For example, are both fine-grained
and uber jars in maven central or only the uber jar?

As a point of reference, the "objectweb-asm" package in Fedora has both an
"all" uber jar and fine-grained jars for those users who only need a subset
of the functionality. I'm sure there are other examples of this too.

über-jars can go against the spirit of maven (that's not to say there isn't
a use for them) as they cause problems for dependency management. I'd just
think that there should be a good reason for excluding those artifacts, so
you don't have to force people to use the über one.

which project you are working? usually a "uber-jar" is created by 
assembler plugin
you should remove the plugin or change the configuration of this one
if is a module just adding %pom_disable_module ...

It's recommended to package all the small JAR files instead of "uber
jar". See http://fedoraproject.org/wiki/Packaging:Java#Split_JAR_files

%mvn_install does "the right thing" by default, but if you really want
to invent your own way of packaging you can always install JAR file
manually w/o using %mvn_install.

It is also possible to skip installation of some JARs using
"%mvn_package ... __noinstall" macro. See man mvn_package
