Including dependencies with a JAR package

[tommycli <to...@ucla.edu>]

I use buildr with the transitive compile.with artifact specifications.

My problem is this: After buildr makes its package, I have a nice JAR file,
but I cannot run it without its dependency JARs.

I don't even know which JARs it depends on. How do you find out which JARs
you need to distribute with your project? Can buildr package all of it into
one file?

Neat!  I added this to our How-To section.

Thanks for sharing.

I am using autojar with builder to find and bundle dependencies to the Jar:

def add_dependencies(pkg)
  tempfile = pkg.to_s.sub(/.jar$/, "-without-dependencies.jar")
  mv pkg.to_s, tempfile

  dependencies = compile.dependencies.map { |d| "-c #{d}"}.join(" ")
  sh "java -jar tools/autojar.jar -baev -o #{pkg} #{dependencies} #{tempfile}"
end

package(:jar).enhance { |pkg| pkg.enhance { |pkg| add_dependencies(pkg) }}

<http://stackoverflow.com/questions/1279419/buildr-package-dependencies-into-a-single-jar/1285293#1285293>

this is a hack and potentially has problems (it uses autojar's
dependency resolution mechanism and therefore cannot find dynamically
added dependencies) but for us it works quite well in practice.

What you want is an uberjar ?
