Jenkins Pipeline插件:执行shell并解析输出 [英] Jenkins Pipeline Plugin: execute shell and parse output

问题描述

我正在使用Jenkins Pipeline插件执行iOS Checkout-Build-Test-Deploy管道.

I am using the Jenkins Pipeline plugin to execute an iOS Checkout-Build-Test-Deploy pipeline.

第一步涉及检查iDevice是否已实际连接(否则其余步骤将不执行).

One step involves checking whether an iDevice is actually connected (otherwise the rest of the steps will not be executed).

我想执行一个外壳命令idevice_id -l(来自 libimobiledevice )，该命令将打印出所连接设备的设备ID，如果失败，则失败没有任何联系.

I want to execute a shell command idevice_id -l (from libimobiledevice) which will print out the device ID of the connected device, or fail if nothing connected.

因此，我设想的步骤将是:

So the steps as I envision them, would be:

• 执行命令sh "/usr/local/bin/idevice_id -l"
• 以某种方式解析输出
如果此命令不返回任何内容，则
• 失败.

• Execute command sh "/usr/local/bin/idevice_id -l"
• parse the output somehow
• fail if this command does not return anything.

我已经阅读了大多数官方文档，但空白处.如何解析sh步骤的输出? 如果我以错误的方式处理此问题，欢迎提出任何其他建议.

I have read most of the official docs, but drew a blank. How do I parse the output of the sh step? If I am approaching this in the wrong way, any other suggestions are welcome.

推荐答案

如此答案(版本)中所述2.4 of

As mentionned in this answer, as of version 2.4 of Pipeline: Nodes and Processes you can use:

def out = sh script: '/usr/local/bin/idevice_id -l', returnStdout: true
