Is it possible to capture the stdout from the sh DSL command in the pipeline

Question

For example   var output sh  echo foo   echo  output  output     I will get   output 0   So  apparently I get the exit code rather than the stdout  Is it possible to capture the stdout into a pipeline variable  such that I could get  output foo as my result

Now  the sh step supports returning stdout by supplying the parameter returnStdout      These should all be performed at the point where you ve    checked out your sources on the slave  A  git  executable    must be available     Most typical  if you re not cloning into a sub directory gitCommit   sh returnStdout  true  script   git rev-parse HEAD   trim      short SHA  possibly better for chat notifications  etc  shortCommit   gitCommit take 6    See this example

You can try to use as well this functions to capture StdErr StdOut and return code   def runShell String command       def responseCode   sh returnStatus  true  script     command   amp  gt  tmp txt       def output    readFile file   tmp txt        if  responseCode    0         println   ERROR    output         throw new Exception    output         else        return    output             Notice    amp  gt name means 1 gt name 2 gt name -- redirect stdout and stderr to the file name

Try this   def get git sha git dir           dir git dir            return sh returnStdout  true  script   git rev-parse HEAD   trim            node BUILD NODE                repo SHA   get git sha  src FooBar git       echo repo SHA             Tested on    Jenkins ver  2 19 1 Pipeline 2 4

Note  The linked Jenkins issue has since been solved   As mention in JENKINS-26133 it was not possible to get shell output as a variable  As a workaround suggested using of writ-read from temporary file  So  your example would have looked like   sh  echo foo  gt  result   def output readFile  result   trim   echo  output  output

I had the same issue and tried almost everything then found after I came to know I was trying it in the wrong block  I was trying it in steps block whereas it needs to be in the environment block          stage  Release                         environment                               my var   sh script   quot  bin bash   assign version     ls  quot     returnStdout  true  trim                                                         steps                                                                println my var
