Getting current timestamp in inline pipeline script using pipeline plugin of hudson

问题

I want to get Getting current timestamp in inline pipeline script using pipeline plugin of hudson. For setting up build display name.

Inline groovy script used:

def jobName = env.JOB_NAME + "_" + new Date()
currentBuild.displayName = "$jobName"
node {
   echo "job name $jobName"
}

Error on console :

org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: 
  Scripts not permitted to use new java.util.Date

回答1:

Jenkins scripts are running in a sandbox, by default the Groovy script doesn't have permissions for some operations.

When you perform an operation without permissions the RejectAccessException is thrown. So you've to execute your script, and then when the exception is thrown go to:

http://yourHost/jenkins/scriptApproval/

And approve the necessary permission:

you can also use this, I needed this in ms so:

echo "TimeStamp: ${currentBuild.startTimeInMillis}"

echo "TimeStamp: ${Util.getTimeSpanString(System.currentTimeMillis())}"

回答3:

There are a bunch of ways to get time depending on what APIs you find most intuitive:

new Date() has since been added to the script-security-plugin whitelist
RunWrapper APIs through use of currentBuild global variable
1. final long startTime = currentBuild.startTimeInMillis: long value of when the build was started in milliseconds
2. final long scheduledTime = currentBuild.timeInMillis: long value of when the build was scheduled in milliseconds
3. final long buildDuration = currentBuild.duration: milliseconds it has taken to build
4. final String buildDurationAsStrong = currentBuild.durationString: duration as a String

Using whitelisted java.time APIs, for example LocalDateTime

import java.time.LocalDateTime
final LocalDateTime currentTime = LocalDateTime.now()
// do stuff with LocalDateTime

Of course, shelling out and using the return value in your script

final String currentTime = sh(returnStdout: true, script: 'date +%Y-%m-%d').trim()

And I'm sure there are other methods, too.

You can also avoid script approvals by using LocalDateTime or LocalDate in string context. These will give you ISO 8601 defaults:

script {
  DATE_TAG = java.time.LocalDate.now()
  DATETIME_TAG = java.time.LocalDateTime.now()
}
sh "echo ${DATETIME_TAG}"

回答5:

Just format the Date object:

stage('Foo') {
  steps {
    script {
        def now = new Date()
        println now.format("yyMMdd.HHmm", TimeZone.getTimeZone('UTC'))
    }
  } 
}
