Description

Original: When setting  {code:java} buildDiscarder([$class: 'EnhancedOldBuildDiscarder', artifactDaysToKeepStr: '',                                                      artifactNumToKeepStr: '',                                                      daysToKeepStr: 7,                                                      numToKeepStr: '',                                                      discardOnlyOnSuccess: false,                                                      holdMaxBuilds: false]), {code} in _properties_, the build is not removed after 7 days if there is only one build remaining.  The documentation for "Days to keep builds" states: {noformat} if not empty, build records are only kept up to this number of days {noformat} so I would assume that the build should be discarded even if it is the last remaining build.

I also tried

buildDiscarder([$class: 'EnhancedOldBuildDiscarder', artifactDaysToKeepStr: '',
                                                     artifactNumToKeepStr: '',
                                                     daysToKeepStr: '1',
                                                     numToKeepStr: '0',
                                                     discardOnlyOnSuccess: false,
                                                     holdMaxBuilds: true]),

The help explicitly states:

Setting Max # of builds to keep to 0 causes any build exceeding the age limit to be discarded.

But the latest build will still remain.

In the Jenkins log there is an entry:

job #2 is not to be removed or purged of artifacts because it’s the last successful build
