如何从Jenkinsfile(groovy)的变量中获取使用执行的Shell命令的输出? [英] How do I get the output of a shell command executed using into a variable from Jenkinsfile (groovy)?

问题描述

我在Jenkinsfile(Groovy)上有类似的内容，我想将stdout和退出代码记录在一个变量中，以便以后使用该信息.

I have something like this on a Jenkinsfile (Groovy) and I want to record the stdout and the exit code in a variable in order to use the information later.

sh "ls -l"

我该怎么做，尤其是似乎不能在Jenkinsfile内部真正运行任何常规代码吗?

How can I do this, especially as it seems that you cannot really run any kind of groovy code inside the Jenkinsfile?

推荐答案

最新版本的管道sh步骤允许您执行以下操作；

The latest version of the pipeline sh step allows you to do the following;

// Git committer email
GIT_COMMIT_EMAIL = sh (
    script: 'git --no-pager show -s --format=\'%ae\'',
    returnStdout: true
).trim()
echo "Git committer email: ${GIT_COMMIT_EMAIL}"

另一个功能是returnStatus选项.

// Test commit message for flags
BUILD_FULL = sh (
    script: "git log -1 --pretty=%B | grep '\\[jenkins-full]'",
    returnStatus: true
) == 0
echo "Build full flag: ${BUILD_FULL}"

这些选项是根据此问题添加的.

These options where added based on this issue.

请参见官方文档 sh命令.
