Error occured in this method :
public void compute(Job job) {
List<Run> builds = job.getBuilds();
for (Run build : builds) {
if (build.getResult().isBetterOrEqualTo(Result.SUCCESS))
addSuccess();
else if (build.getResult().isBetterOrEqualTo(Result.UNSTABLE))
addUnstable();
else if (build.getResult().isBetterOrEqualTo(Result.FAILURE))
addFail();
}
}
build.getResult() seems to be null.
I've made a groovy script to find job where a build can have a null result :
Jenkins.instance.items.findAll{job -> job.isBuildable()}.each{ Job job ->
if(job.getBuilds() != null) {
for (Run build : job.getBuilds()) {
if(build.getResult() == null) {
println "('"+build.number+"') null : " + job.name
}
}
}
}
All resulting jobs are currently building.
It seems that the plugin don't check if the job is currently building, that result in a NullPointerException here.
