如何在詹金斯管道构建日志中禁用命令输出

问题描述

我正在使用 Jenkinsfile 编写管道脚本.

I am using Jenkinsfile for scripting of a pipeline.

有什么方法可以禁止在构建日志中打印已执行的 shell 命令?

Is there any way to disable printing of executed shell commands in build logs?

这里只是一个简单的 jenkins 管道示例:

Here is just a simple example of a jenkins pipeline:

node{
  stage ("Example") {
    sh('echo shellscript.sh arg1 arg2')
    sh('echo shellscript.sh arg3 arg4')
  }
}

在控制台日志中产生以下输出:

which produces the following output in console log:

[Pipeline] node
Running on master in /var/lib/jenkins/workspace/testpipeline
[Pipeline] {
[Pipeline] stage
[Pipeline] { (Test)
[Pipeline] sh
[testpipeline] Running shell script
+ echo shellscript.sh arg1 arg2
shellscript.sh arg1 arg2
[Pipeline] sh
[testpipeline] Running shell script
+ echo shellscript.sh arg3 arg4
shellscript.sh arg3 arg4
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS

基本上我想禁用命令本身的打印.

Basically I would like to disable printing of the commands itself.

+ echo shellscript.sh arg1 arg2
+ echo shellscript.sh arg3 arg4

推荐答案

默认情况下，Jenkins 使用标志 -xe 启动 shell 脚本.-x 启用额外的日志记录.-e 如果里面的任何命令返回非零退出状态，则使脚本退出.要重置标志，我建议两个选项:

By default Jenkins starts shell scripts with flags -xe. -x enables additional logging. -e makes the script exit if any command inside returns non-zero exit status. To reset a flag I'd suggest two options:

1. 在脚本正文中调用 set +x.
2. 在没有 -x 的情况下传递自定义 shebang 行:sh('#!/bin/sh -e' + 'echo shellscript.sh arg1 arg2')

1. Call set +x in the body of your script.
2. Pass custom shebang line without -x: sh('#!/bin/sh -e' + 'echo shellscript.sh arg1 arg2')

至于第二个选项，您可以为方便定义一个包装函数，该函数将在脚本前面加上自定义 shebang，然后调用 sh

As for the second option you can define a wrapper function for convenience which will prepend the script with custom shebang and then call sh

def mysh(cmd) {
    sh('#!/bin/sh -e
' + cmd)
}
