Jenkins Gerrit轮询失败:不断触发构建

Question

因此,我们在Jenkins CI构建管理器上使用Gerrit Trigger(2.23.0)并使用docker容器进行实际构建.

Gerrit Repo轮询最近出现在我们的一些分支机构中的问题是失败并导致它每次都"检测到变化",所以尽管没有变化,它仍在不断重建.

检查Gerrit Repo Polling Log以查找任何受影响的作业,并提供以下输出之一:

Started on Feb 1, 2017 3:12:25 PM
Polling SCM changes on aosp-host
[workspace] $ repo init -u http://xxx.xxx.xxx.xxx/git/project/platform/manifest.git -b branch -m branch.xml

fatal: Not a git repository: '/home/jenkins/workspace/.repo/manifests.git'
fatal: cannot obtain manifest http://xxx.xxx.xxx.xxx/git/project/platform/manifest.git
Done. Took 1 min 19 sec
Changes found

或者,如果构建已经构建(gerrit在进行scm轮询之前等待构建完成)

Started on Feb 2, 2017 3:24:15 AM
Polling SCM changes on aosp-host
[workspace] $ repo init -u http://xxx.xxx.xxx.xxx/git/project/platform/manifest.git -b branch -m branch.xml
fatal: cannot make /home/jenkins/workspace/.repo/repo directory: File exists
Done. Took 2 hr 4 min
Changes found

由此失败触发的构建使用相同的命令并正常工作:

[workspace] $ repo init -u http://xxx.xxx.xxx.xxx/git/project/platform/manifest.git -b branch -m branch.xml

导航到清单目录,我们看到症状:

jenkins@f052b3453d95:~/workspace/.repo$ ll

同

lrwxrwxrwx 1 jenkins jenkins    20 Dec 20 10:13 manifest.xml -> manifests/branch.xml

以红色突出显示,因为branch.xml找不到关联...所以从上面的Gerrit Log是准确的,它没有init正确.这可以通过repo status主目录中的a确认:

jenkins@f052b3453d95:~/workspace$ repo status
Traceback (most recent call last):
  File "/home/jenkins/workspace/.repo/repo/main.py", line 531, in <module>
    _Main(sys.argv[1:])
  File "/home/jenkins/workspace/.repo/repo/main.py", line 507, in _Main
    result = repo._Run(argv) or 0
  File "/home/jenkins/workspace/.repo/repo/main.py", line 180, in _Run
    result = cmd.Execute(copts, cargs)
  File "/home/jenkins/workspace/.repo/repo/subcmds/status.py", line 130, in Execute
    all_projects = self.GetProjects(args)
  File "/home/jenkins/workspace/.repo/repo/command.py", line 140, in GetProjects
    all_projects_list = manifest.projects
  File "/home/jenkins/workspace/.repo/repo/manifest_xml.py", line 350, in projects
    self._Load()
  File "/home/jenkins/workspace/.repo/repo/manifest_xml.py", line 407, in _Load
    self.manifestProject.worktree))
  File "/home/jenkins/workspace/.repo/repo/manifest_xml.py", line 443, in _ParseManifestXml
    root = xml.dom.minidom.parse(path)
  File "/usr/lib/python2.7/xml/dom/minidom.py", line 1918, in parse
    return expatbuilder.parse(file)
  File "/usr/lib/python2.7/xml/dom/expatbuilder.py", line 922, in parse
    fp = open(file, 'rb')
IOError: [Errno 2] No such file or directory: '/home/jenkins/workspace/.repo/manifest.xml'

问题是,repo init -u <url> -m branch.xml通过命令行运行正常,并生成一个有效的仓库.

可以为此问题提供任何见解？
