 running this pipeline: def do_i(p) { return { echo "$p" for (i = 0; i < 10; i++)  { echo "i: $i" }  } } stage('i') { parallel( "x" : do_i('xx'), "y" : do_i('yy') ) } produces this output: [Pipeline] stage [Pipeline] {  [Pipeline] parallel [Pipeline] [x] { (Branch: x) [Pipeline] [y]  { (Branch: y) [Pipeline] [x] echo [x] xx [Pipeline] [y] echo [y] yy [Pipeline] [x] echo [x] i: 0 [Pipeline] [y] echo [y] i: 1 [Pipeline] [x] echo [x] i: 2 [Pipeline] [y] echo [y] i: 3 [Pipeline] [x] echo [x] i: 4 [Pipeline] [y] echo [y] i: 5 [Pipeline] [x] echo [x] i: 6 [Pipeline] [y] echo [y] i: 7 [Pipeline] [x] echo [x] i: 8 [Pipeline] [y] echo [y] i: 9 [Pipeline] [y] } [Pipeline] [x] echo [x] i: 10 [Pipeline] [x] } [Pipeline] // parallel [Pipeline] } [Pipeline] // stage [Pipeline] End of Pipeline Note how i is incremented as if both threads were referring to the same variable i. If I modify the for loop to: for (int i = 0; i < 10; i++) then it works as I expect, where each thread has its own i variable: [Pipeline] stage [Pipeline] {  [Pipeline] parallel [Pipeline] [x] { (Branch: x) [Pipeline] [y]  { (Branch: y) [Pipeline] [x] echo [x] xx [Pipeline] [y] echo [y] yy [Pipeline] [x] echo [x] i: 0 [Pipeline] [y] echo [y] i: 0 [Pipeline] [x] echo [x] i: 1 [Pipeline] [y] echo [y] i: 1 [Pipeline] [x] echo [x] i: 2 [Pipeline] [y] echo [y] i: 2 [Pipeline] [x] echo [x] i: 3 [Pipeline] [y] echo [y] i: 3 [Pipeline] [x] echo [x] i: 4 [Pipeline] [y] echo [y] i: 4 [Pipeline] [x] echo [x] i: 5 [Pipeline] [y] echo [y] i: 5 [Pipeline] [x] echo [x] i: 6 [Pipeline] [y] echo [y] i: 6 [Pipeline] [x] echo [x] i: 7 [Pipeline] [y] echo [y] i: 7 [Pipeline] [x] echo [x] i: 8 [Pipeline] [y] echo [y] i: 8 [Pipeline] [x] echo [x] i: 9 [Pipeline] [x] }
