Best/most idiomatic way to do parallel tasks that are largely the same?

[Adam Paul]

Hello,

Let's say I have a product that needs to build on two different architectures (indeed, I do).  The build steps are exactly the same, only the architecture differs.  What is the best way to do this in parallel in a pipeline without duplicating the code for each architecture.  The example below is simple, but my real world one isn't so much.

eg. instead of:

parallel(

    "sparc": {

        def arch="sparc"

        do_stuff(arch)

        do_more_stuff(arch)

    },

    "i386": {

        def arch="i386"

        do_stuff(arch)

        do_more_stuff(arch)

    }

)

There is:

def testList = ["sparc","i386"]

def branches = [:] 

for (int i = 0; i < testList.size() ; i++) {

       String arch=testList[i]

       stage ("branch_${arch}"){ 

            branches["branch_${arch}"] = { 

                node (){

                    do_stuff(arch)

                    do_more_stuff(arch)

                }

            }

      }

}

parallel branches

which works, but I'm wondering if there is a better/more idiomatic way to do this?

Thanks!
