How to iterate over classpath or how to unwrap T?

[Sailsman63]

Working on trying to construct a staging directory for a full application. I need to place all runtime dependencies in a specific folder, call it T.dest / "lib".

runClasspath is of type [T[Seq[PathRef]]]. I can't figure out how to access that internal Seq for the purpose of iterating over it and copying each jar to lib/

Or is there a more idiomatic way of doing this?

def copyToLib(): Command[Unit] = T.command {
  runClasspath()
    .map(_.path) // the path
    .filter(p => os.exists(p) && os.isFile(p)) // only existing files
    .foreach(p => os.copy.over(p, millSourcePath / "lib" / p.last)) // copy files flat into lib/
}

Thanks! It turns out that the part I was missing was the difference between runClasspath and runClasspath(). Probably comes down to me being a total Scala noob.
