when read the build log, i saw that sometime it got a wrong build number, which is the last one of the triggered build. I also readed the source of plugin, and found that "Validate the build number via parameters" try to query build #n-2 to #n+2 (n means the triggered build number), i didn't know why, is there who can tell me? And I guess that query the build immediately after triggered may cause the problem above, because the build may be started to run after a few seconds delay. If add sleep for seconds before build could solve this?
