Jenkins
坑1:sh: adb: command not found
背景:在任务中使用了adb命令
adb 使用时要在服务器上配Android-home的环境变量的
配置完成之后发现在服务器上 adb OK,但是在jenkins 执行job时不OK
参考一下两篇文档
https://stackoverflow.com/questions/29216244/jenkins-build-failed-due-to-missing-android-sdk
http://www.linuxdiyf.com/linux/28771.html
1.在jenkins 设置里配置Android-home,然而并没有用
2.在Execute shell 里将#!/bin/bash 改成 #!/bin/bash -ilex
实测是有用的~
3.实际挨个试了下#!/bin/bash -ilex中的各个参数 发现有用的是-l
‘‘‘
-l Make bash act as if it had been invoked as a login shell (see
INVOCATION below).
When bash is invoked as an interactive login shell, or as a non-inter-
active shell with the --login option, it first reads and executes com-
mands from the file /etc/profile, if that file exists. After reading
that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile,
in that order, and reads and executes commands from the first one that
exists and is readable. The --noprofile option may be used when the
shell is started to inhibit this behavior.
‘‘‘
综上,就是加载了/etc/profile或者其他几个配置环境变量的文件
所以直接改成在 shell 脚本里增加source /etc/profile就好啦~
坑2 Jenkins + python 的任务,console output 没有及时输出日志
期初是以为是 #!/bin/bash -ilex 中四个参数导致console output 没有输出,后来突然意识到是python的print应该有buffer的问题
https://stackoverflow.com/questions/22826006/how-to-get-python-print-result-in-jenkins-console-output
https://stackoverflow.com/questions/11631951/jenkins-console-output-not-in-realtime
有两种解释
1.jenkins 要输入换行符才能展示数据
Any output to stdout
from a process spawned by Jenkins should be captured by Console Output. One caveat is that it won‘t be displayed until a newline character is printed, so make sure your lines are terminated.
2.print有buffer
ruby
or python
or any sensible scripting language will buffer the output; this is in order to minimize the IO; writing to disk is slow, writing to a console is slow...flush()
‘ed automatically after you have enough data in the buffer with special handling for newlines. e.g. writing a string without newline then sleep()
would not write anything until after the sleep()
is complete (I‘m only using sleep
as an example, feel free to substitute with any other expensive system call).解决方法看到两个
1.print 信息后加sys.stdout.flush()
2.
for python
, you can use python -u
or the environment variable PYTHONUNBUFFERED
to make stdin/stdout/stout
not buffered, but there are other solutions that do not change stdin
or stderr
export PYTHONUNBUFFERED=1
