Jenkins在openshift上构建失败/取消

Question

我在使用 jenkins 将新代码推送到我的 openshift 应用程序时遇到问题。我已经从 Web 控制台管理员启用了 jenkins，它可以工作（没有自定义设置）。但是，在将新更改推送到我的应用程序之前，我必须至少推送 2 次。
我有青铜计划。我使用 3 个应用程序（主应用程序、数据库应用程序、jenkins），在推送时，jenkins 创建了第 4 个应用程序。
推送新版本的应用程序需要很长时间，因为每次推送后我都会升级搜索索引。当我第一次推送时，这就是我得到的：

git push origin
Counting objects: 38, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (18/18), done.
Writing objects: 100% (20/20), 2.33 KiB | 0 bytes/s, done.

remote: 
remote: Waiting for build to schedule.....................................................................
remote: **BUILD FAILED/CANCELLED**
remote: Please see the Jenkins log for more details via 'rhc tail'
remote: !!!!!!!!
remote: Deployment Halted!
remote: If the build failed before the deploy step, your previous
remote: build is still running.  Otherwise, your application may be
remote: partially deployed or inaccessible.
remote: Fix the build and try again.
remote: !!!!!!!!
remote: An error occurred executing 'gear postreceive' (exit code: 1)
remote: Error message: CLIENT_ERROR: Failed to execute: 'control post-receive' for /var/lib/openshift/55a0310e4...4/jenkins-client
remote: 
remote: For more details about the problem, try running the command again with the '--trace' option.

这是我的第二次推送：

$ git push origin

Compressing objects: 100% (6/6), done.
Writing objects: 100% (6/6), 481 bytes | 0 bytes/s, done.

为什么我的第一次推送总是失败？我在 rhc tail myapp 中没有看到任何关于 jenkins 的错误

Answer 1

当我push first提交时，它会大喊BUILD FAILED/CANCELLED。在第二次推动它是成功的。如果我在第二次之后立即进行第三次推动，这也是成功的。几乎就像詹金斯应用程序会休眠，但它不能。我有青铜计划，我尝试加载 jenkins url，所以我确定 jenkins 应用程序正在运行。
我能想到的第一次推送失败的唯一可能原因是我有 16 个应用程序中的 3 个，并且可能第 4 个应用程序创建时间太长，并且 Jenkins 没有等待并以错误结束。

所以每次我想要推送我的应用的新版本时，我都会继续推送两次而不是一次。
