shade is a uber jar plugin. there are 3 uber jar plugins that matter, shade, maven-assembly, and proguard.
for beginners: all of them work more or less by merging a project into a single new jar just reading the pom dependencies. maven assembly does the least work. good for quick jobs shade-plugin sometimes does a good job but imho if it works once you are buying into a false sense of security and will be bitten as you grow a project. proguard is industrial strength and imho returns the best result for investing in rtfm. all of the above have a special configs to do parts and pieces. a beginner's mistake would be to pursue that course of action. don't. make a simple uber-jar project with one output jar combined from all of the input jars, and learn how to exclude collisions. if you have some proprietary jar with no source spend some time with jad to make source and refactor your packages to do the above, "simple" uber-jar On Mon, Jul 7, 2014 at 2:15 PM, Robert James <[email protected]> wrote: > How do I run Maven Shade on a standalone jar (ie with no sources to > build from)?
