I am using parallelization for my builds. Let's say if I write my code like this and my job name is "newjob"

parallel ( "stream 1" : { node("node1") { unstash "binary" sh "sleep 20s" sh "echo hstream1" } }, "stream 2" : { node("node1") { unstash "binary" sh "echo hello2" sh "hashtag fail" } } )

what it will do is it creates a workspace on node->node 1 for stream1 as /var/tmp/build/newjob and for the stream2 as /var/tmp/build/newjob@2 or stream1 as /var/tmp/build/newjob@2 and for stream 1 as /var/tmp/build/newjob

for a code base like mine @ symbol will create an issue and it fails my build 

I haven't seen this issue in freestyle upstream-downstream parallel jobs but in workflow, I am seeing this do let me know if you need more information
