Jenkins Groovy script to execute shell commands
提问by WillBroadbent
I'm using a groovy script to calculate my build duration and publish a metric to Hosted Graphite, from the command line the following curl will result with the intend effect:
我正在使用一个 groovy 脚本来计算我的构建持续时间并将指标发布到托管石墨，从命令行将产生以下卷曲并产生预期效果：
echo {someMetricHere} | nc carbon.hostedgraphite.com 2003
However in my groovy script the last step having generated a metric is to run the following:
但是，在我的 groovy 脚本中，生成指标的最后一步是运行以下命令：
"echo "+ metric +" | nc carbon.hostedgraphite.com 2003".execute()
Its returning:
它的回归：
Caught: java.io.IOException: Cannot run program "|": error=20, Not a directory java.io.IOException: Cannot run program "|": error=20, Not a directory at hudson8814765985646265134.run(hudson8814765985646265134.groovy:27) Caused by: java.io.IOException: error=20, Not a directory ... 1 more
捕获：java.io.IOException：无法运行程序“|”：错误=20，不是目录 java.io.IOException：无法运行程序“|”：错误=20，不是 hudson8814765985646265134.run(hudson8814765985646265134. :27) 由：java.io.IOException: error=20, Not a directory ... 1 more
I assume the command doesn't understand the "|" part of the command, any suggestions how I can fix this script to run the intended bash? I thought it might be possible to create a .sh file in the workspace but am not sure how.
我假设该命令不理解“|” 命令的一部分，对如何修复此脚本以运行预期的 bash 有何建议？我认为可以在工作区中创建一个 .sh 文件，但我不确定如何。

to use pipe |try this code:
使用管道|试试这个代码：
// this command line definitely works under linux:
def cmd = ['/bin/sh', '-c', 'echo "12345" | grep "23"']
// this one should work for you:
// def cmd = ['/bin/sh', '-c', 'echo "${metric}" | nc carbon.hostedgraphite.com 2003']
cmd.execute().with{
def output = new StringWriter()
def error = new StringWriter()
//wait for process ended and catch stderr and stdout.
it.waitForProcessOutput(output, error)
//check there is no error
println "error=$error"
println "output=$output"
println "code=${it.exitValue()}"
}
the output:
输出：
error=
output=12345
code=0

I think something is wrong with the concatenation you did.
我认为你所做的连接有问题。
This code should work:
此代码应该工作：
"echo ${metric} | nc carbon.hostedgraphite.com 2003".execute()

A simpler way to achieve this is to use the Jenkins Job DSL. It features a shellcommand that can be issued from within a given step. For example:
实现此目的的更简单方法是使用Jenkins Job DSL。它具有shell可以从给定step. 例如：
// execute echo command
job('example-1') {
steps {
shell('echo Hello World!')
}
}
// read file from workspace
job('example-2') {
steps {
shell(readFileFromWorkspace('build.sh'))
}
}
You can find the reference here.
您可以在此处找到参考。

If you have to pass in a variable to a groovy script, you do it using ${variableName}. Double quotes are not interpreted like the way you think they would, and every compiler treats it in a weird way.
如果必须将变量传递给 groovy 脚本，请使用${variableName}. 双引号不会像你想象的那样解释，每个编译器都以一种奇怪的方式对待它。
In your case, the below line should help to do the thing you want:
在您的情况下，以下行应该有助于做您想做的事情：
sh "echo ${metric} | nc carbon.hostedgraphite.com 2003"
