Configuration:

Jenkins version: 2.55

pipeline:groovy plugin: 2.29

pipeline:basic Steps plugin:2.4

pipeline:nodes and processes plpugin: 2.10

pipeline: shared groovy libraries: 2.7

I have a master (ubuntu machine) and a slave "testSlave" (windows machine)

I have the following groovy script in my jenkinsfile in github.

node('TestSlave') {
stage('Update Slave Code') {
bat 'start cmd.exe /c UpdateSlaveCode.bat ' + Branch
sleep(5)
}

stage('Compile') {
bat 'start cmd.exe /w /k CompileAndTest.bat'
sleep(5)
}

stage('Merge Code') {
bat 'start cmd.exe /w /c Merge.bat '+masterBranch +" "+Branch
sleep(5)
}

Problem: stage('Merge Code') starts before stage('Compile') finishes executing. Note that i am calling a batch file(CompileAndTest.bat) within the bat command.

                                    bat 'start cmd.exe /w /k CompileAndTest.bat'

So Stage('Compile') just invokes the bat command and considers that stage as complete, however it is yet to finish executing.

The stage('Merge Code') should wait till stage('Compile') completes

CompileAndTest.bat is as follows:

       echo 'Compiling and testing...'
       set "mvnErr="
       call mvn clean test || set mvnErr=1

       if %mvnErr%==1 (
       echo 'Maven test failed'
       exit /B 1
       )
       echo '...done testing'
