Jenkins rurociąg błąd java.io.NotSerializableException java.util.regex.Matcher nawet z @NonCPS

Question

używam @NonCPS przed moim Jenkinsfile funkcji, która wykonuje dopasowanie regex i nadal jestem coraz java.io.NotSerializableException java.util.regex.Matcher błąd nawet z @NonCPS adnotacji .

Uwaga, funkcja ta jest wielokrotnie wywoływana, a wyjątek pojawia się dopiero po wykonaniu meczu.

Oto mój kod:

@NonCPS 
def extractEndTime(logLine) { 
    def MY_REGEX = /.*(20[0-9]{2}-[0-9]{2}-[0-9]{2}).([0-9]{2}:[0-9]{2}:[0-9]{2}).*\"\w+\"\sthe text\s(\w+)\./ 
    m = (logLine =~ TEST_LOGLINE_END_REGEX) 
    if (m.count) { 
     return [m[1],m[2],m[3]] 
    } else { 
     return null 
    } 
} 

Wyjście gdy robi Jenkins produkcji:

Answer 1

Prawdopodobnie ze względu na zakres zmiennej m. Spróbuj ograniczyć ją def tak:

def m = (logLine =~ TEST_LOGLINE_END_REGEX) 

Bez def zmienna jest tworzona w globalnym skryptu wiązania i stąd nadal istnieje po wyjściu z tej metody.

Answer 2

Jenkins wymaga, aby wszystkie zmienne były poddawane serializacji, ponieważ stan potoku jest okresowo zapisywany na dysku w przypadku przerwania, takich jak restart serwera. Ta funkcja pozwala potokom utrzymywać ich stan i kontynuować nawet po zrestartowaniu serwera. Zmienne typu Matcher nie są przekształcalne do postaci szeregowej i wymagają dodatkowej pracy dewelopera.
