Runtime ClassLoader Instead of Build ClassLoader

[Robert Fischer]

I'd like to call a Java class, but use the runtime classloader instead of the build classloader for
resolving and executing the class.  Is there an easy way to do this?

The wider background: I'm executing org.jruby.Main#main to execute JRuby scripts.  I'd like those
scripts to use the runtime classloader so I don't have to keep building up the
buildscript.dependencies closure.

Depends what do you mean by the 'runtime classloader'. What stuff do you
need to be visible (or not visible)?

I'd like to provide the dependencies specified in the "dependencies" closure, not by the stuff in
buildscript.dependencies.

There's no built-in method for doing this. It's quite easy to script it
up, however:

ClassLoader loader = new URLClassLoader(configurations.runtime.collect {
it.toURI().toURL() } as URL[])

It might be a good thing to be able to do something like:

cl = configurations.runtime.getAsClassLoader()
cl = configurations.runtime as ClassLoader

or possibly just

cl = new URLClassLoader(configurations.runtime as URL[])
