java.lang.StackOverflowError während der Verwendung von emailtext Plugin

Question

Am Ende meiner Pipeline möchte ich eine Mail senden, um zu sehen, ob meine Builds erfolgreich sind. Deshalb verwende ich die folgende groovy Skript:

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 
) 

Grundsätzlich ist der Code funktioniert aber nur, wenn ich die letzte Zeile aus kommentieren (build16). Die Variable ist korrekt zugewiesen. Aber wenn ich den Code ausführe, bekomme ich einen java.lang.StackOverflowError. (Über 1000 Zeilen)

kurz snipped:

Answer 1

das Problem gelöst. Die große Anzahl von '+' Operatoren verursachte den Überlauf. Jetzt bin ich usiung java.lang.StringBuilder und .append, um meine Ausgangsschnur zu bauen.
