所以这工作正常：
properties([
//https://stackoverflow.com/questions/35370810/how-do-i-use-jenkins-pipeline-properties-step
parameters([
//note here that the default will be the element you have as a first choice in the array
choice(name: 'environmentName', choices: ['PROD', 'STAGE'], description: 'Choose the environment you want to run automation tests'),
]),
//explained here: https://stackoverflow.com/questions/44113834/trigger-hourly-build-from-scripted-jenkinsfile
//recall that ANY change you do here you will need to execute the job once manually for the new cron parameter to be updated, pushing it is not enough
//minutes, hours, day of month, month, day of week //H is any first available (here minute) of the hour according to resources
pipelineTriggers([
parameterizedCron('*/2 * * * 0-4 %environmentName=STAGE')
]),
])
但是，当尝试在多行中定义它时，如下所述：https://github.com/jenkinsci/parameterized-scheduler-plugin/blob/master/README.md https://github.com/jenkinsci/parameterized-scheduler-plugin/blob/master/README.md
那么这不起作用：
properties([
//https://stackoverflow.com/questions/35370810/how-do-i-use-jenkins-pipeline-properties-step
parameters([
//note here that the default will be the element you have as a first choice in the array
choice(name: 'environmentName', choices: ['PROD', 'STAGE'], description: 'Choose the environment you want to run automation tests'),
]),
//explained here: https://stackoverflow.com/questions/44113834/trigger-hourly-build-from-scripted-jenkinsfile
//recall that ANY change you do here you will need to execute the job once manually for the new cron parameter to be updated, pushing it is not enough
//minutes, hours, day of month, month, day of week //H is any first available (here minute) of the hour according to resources
pipelineTriggers([
//cron('H 23 * * 0-4') //this works with the DEFAULT parameters
parameterizedCron { //this is documented here: https://github.com/jenkinsci/parameterized-scheduler-plugin/blob/master/README.md
parameterizedSpecification( '''
# leave spaces where you want them around the parameters. They'll be trimmed
#*/2 * * * * %environmentName=STAGE;SomeOtherVariable=Pluto
#you may repeat multiple configuration if you want
*/2 * * * 0-4 %environmentName=STAGE
''' )
}
]),
])
执行詹金斯作业后收到的异常是这样的：
java.lang.ClassCastException: org.jenkinsci.plugins.parameterizedscheduler.ParameterizedTimerTrigger.parameterizedSpecification expects class java.lang.String but received class org.jenkinsci.plugins.workflow.cps.CpsClosure2
所以看来parameterizedSpecification发现方法正常，它只抱怨传递的参数，但传递的参数只是一个多行字符串。
这是正确的 Groovy 语法问题还是其他问题？完全不确定。我们需要你的帮助
