Get all logs of the current Jenkins build with currentBuild.rawBuild.getLog

Question

I want all my jenkins logs of my current build in groovy

env.logs = currentBuild.rawBuild.getLog(1000).join('\n')

This works, but the problem here is I have to specify the amount of lines. When I use:

env.logs = currentBuild.rawBuild.getLog().join('\n')

env.logs is empty. What is the right command to get all the logs without specifying the amount of lines. Is this possible?

currentBuild.rawBuild.log seems to work but is deprecated?

Answer 1

You can use the getLog method with a max value getLog(Integer.MAX_VALUE)

Answer 2

This is working for me - it reads the actual log file instead of using the API:

logFileContent = new File("${JENKINS_HOME}/jobs/${JOB_NAME}/builds/${BUILD_NUMBER}/log").collect {it}
