Jenkins ver. 2.73.3
P4 Plugin ver. 1.8.12
I created a very simple pipeline job to test polling without a sync (preview only mode) and it is failing with the below error:
P4 Task: failed: java.lang.NullPointerException
There is no exception logged in the Jenkins log. The exception seemed to occur on the slave, so I checked the swarm log and nothing was found.
Here is the pipeline script:
pipeline {
agent {
label "CentOS6"
}
stages {
stage("Init") {
steps {
checkout perforce(
credential: 'p4-hbase-build',
populate: previewOnly(quiet: true),
workspace: manualSpec(
charset: 'none',
name: 'jenkins-${NODE_NAME}-${JOB_NAME}-${EXECUTOR_NUMBER}',
pinHost: false,
spec: clientSpec(
allwrite: false,
backup: false,
clobber: true,
compress: false,
line: 'LOCAL',
locked: false,
modtime: false,
rmdir: false,
serverID: '',
streamName: '',
type: 'WRITABLE',
view: '//sandbox/hdara/test/... //jenkins-${NODE_NAME}-${JOB_NAME}-${EXECUTOR_NUMBER}/...'
)
)
)
}
}
stage("Run") {
steps {
echo "INFO: Running..."
sh "export"
}
}
}
}
Here is the job console output:

I tried to capture the NPE by starting swarm JVM in debug mode and put a breakpoint via jdb. Here is the stacktrace:

Looks like iclient is null as seen in the below jdb output:
