At the end of my pipeline I want to send a Mail to see if my builds are successfull. Therefore I use the following groovy script:

emailext (
to: 'mail@example.com',
subject: 'Job: ' + env.JOB_NAME + ' / ' +'Build #' + env.BUILD_NUMBER + ' / ' + ' Summary',
body:'Integrity Checkout: '+ '\t\t\t' + checkoutStatus +'\n\n' + 'Build1: '+ '\t\t\t' + Build1 + '\n' 
                                                       + 'Build2 :'+ '\t' + Build2 + '\n'
                                                       + 'Build3 :'+ '\t' + Build3 + '\n'
                                                       + 'Build4 :'+ '\t' + Build4 + '\n'
                                                       + 'Build5 :'+ '\t' + Build5 + '\n'
                                                       + 'Build6 :'+ '\t' + Build6 + '\n'
                                                       + 'Build7 :'+ '\t' + Build7 + '\n'
                                                       + 'Build8 :'+ '\t' + Build8 + '\n'
                                                       + 'Build9 :'+ '\t' + Build9 + '\n'
                                                       + 'Build10:'+ '\t' + Build10 + '\n'
                                                       + 'Build11:'+ '\t' + Build11 + '\n'
                                                       + 'Build12:'+ '\t' + Build12 + '\n'
                                                       + 'Build13:'+ '\t' + Build13 + '\n'
                                                       + 'Build14:'+ '\t' + Build14 + '\n'
                                                       + 'Build15:'+ '\t' + Build15 + '\n'
                                                       + 'Build16:'+ '\t' + Build16,
attachLog: true,
compressLog: true
)

Basically the code is working but only if I comment out the last line (build16). The variable is correctly assigned. But if I execute the code I get a java.lang.StackOverflowError. (over 1000 lines)

Solved the problem. The massive amount of '+' operators caused the Overflow. Now I am usiung

java.lang.StringBuilder

and

.append

to build my output string.
