Description

PostbuildTask loads the build log into memory, causing OutOfMemoryException.
https://issues.jenkins.io/browse/JENKINS-12830

We started hitting this problem this week, see discussion here:
https://the-asf.slack.com/archives/CK23JSY2K/p1643063068079200?thread_ts=1643052183.068300&cid=CK23JSY2K

Fix is to use the PostBuildTask plugin instead, which does not perform any reading off or matching on the build log.
