How to remove unnecessary classes from fastutil with maven?

[Dawid Weiss]

What do you mean?

I mean a library is huge. In production I would like to use smaller one without classes that I actually not to use in my project. I want to know does somebody have experience in maven plugins usage to perform this task?

Use Eric Lafortune's proguard. I'm sure there's a maven plugin for it,
but I didn't look around.

Thank you for advise. That is I am exploring now. May be somebody has an example pom?

Use maven-shade-plugin. It will let you copy the Fastutil classes you
use into a single jar with your project.

I'd still recommend proguard -- it has a lot more tuning knobs and can
do pretty much anything what you may come up with (single jar output,
package flattening, renaming, whatever). It's one of the greatest
bytecode engineering tool I've come across.

Code example is really appreciated. Anyway thank you very much indeed.

Of course it is possible with Maven. Like I said: if you google around
there's plenty of solutions. I use my own version of Proguard to trim
and repackage third party dependencies here:

https://github.com/carrotsearch/randomizedtesting/blob/master/ant-junit4/pom.xml

But there are also more "standard" solutions like maven shade plugin:

http://maven.apache.org/plugins/maven-shade-plugin/

Like they say: everything is possible (given more time, resources,
money or any combination of the above...).

Do you mean that shade plugin remove unnecessary classes from
dependencies?
Is you proguard pom acceptable for regular proguard?

RTFM and search for an attribute "minimizeJar"...
http://maven.apache.org/plugins/maven-shade-plugin/shade-mojo.html

You haven't looked at that pom, have you? It uses an external proguard
JAR embedded in the project so you can substitute any version of
proguard you like (or make it a dependency if you wish). I use a
custom version because I need special package renaming which isn't in
proguard by default.

This is my final e-mail. I recommend that you read this before asking
more questions:

I am sorry. Thank you vey much. You have done a lot of.

[Nikolay Rychkov]

It looks like this is a solution. I will try.
