Build flow job gets indecipherable Groovy error

[CLOSE Dave]

I have a Jenkins job using the build flow plugin. A portion of it looks
like the code below.

parallel (
{ ignore ( FAILURE ) { build ( "job1", BRANCH: params [ "BRANCH" ] ) } },
{ ignore ( FAILURE ) { build ( "job2", BRANCH: params [ "BRANCH" ] ) } }
)

I'd like to replace the BRANCH parameter with a call to a script so that
I can use a fallback branch in some cases. Doing so seems fairly tricky
but I think I got it working, sort of. The code now looks like this.

branchName = build.buildVariableResolver.resolve("BRANCH")
def chkbranch ( String product, String branch ) {
def cmd = ["/bin/bash", "-c", "/home/jenkins/bin/chkbranch"+"
"+product+" "+branch] // Build the command string to run
def ans = cmd.execute().text // Run the command
return "$ans"[0..-2] // Chomp the answer before returning
}
parallel (
{ ignore ( FAILURE ) { build ( "job1", BRANCH: chkbranch ( "job1",
branchName ) ) } }
{ ignore ( FAILURE ) { build ( "job2", BRANCH: chkbranch ( "job2",
branchName ) ) } }
)

But this doesn't work. It throws a completely indecipherable Groovy
error and I'm lost. But it does work if I remove the "parallel"
grouping. Unfortunately, that extends the time to run the job excessively.

The error looks something like the following. Any ideas?

Hi,
I am not sure that this is what cause the error but I think you forgot a comma between the two ignores

Thanks for the reply. But that was just a cut-and-paste error. I don't
actually have the version quoted as the parallel statements are
commented in my copy. Without the parallel, the commas should not be
present. When I removed the comments to include the code in my message,
I forgot to put the commas back.

I'm still stymied by the obtuse Groovy error and hoping for some
enlightenment.

This will probably not help you, but I tried your example, and it worked.
