Jenkins管道java.io.NotSerializableException java.util.regex.Matcher错误，即使使用@NonCPS [英] Jenkins pipeline java.io.NotSerializableException java.util.regex.Matcher error even with @NonCPS

问题描述

我在执行正则表达式匹配的Jenkinsfile函数前面使用了@NonCPS，即使使用@NonCPS批注，我仍然会收到java.io.NotSerializableException java.util.regex.Matcher错误.

I am using @NonCPS in front of my Jenkinsfile function which performs a regex match and i'm still getting java.io.NotSerializableException java.util.regex.Matcher error even with the @NonCPS annotation.

请注意，它会多次调用该函数，并且只有在实际匹配后才会发生该异常.

Note, it calls the function many times and the exception only occurs once a match is actually made.

这是我的代码:

@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
    }
}

推荐答案

可能是由于m变量作用域. 尝试像这样用def限制它:

Probably due to the m variable scope. Try restrict it with def like this:

def m = (logLine =~ TEST_LOGLINE_END_REGEX)

在没有def的情况下，变量是在全局脚本绑定中创建的，因此从方法退出后仍然存在.

Without def a variable is created in a global script binding and hence still exists after exiting from the method.
