用Jenkins和Groovy写入文件 [英] Write to file with Jenkins and Groovy

问题描述

在运行我的Jenkins版本时，在这种情况下，我需要使用版本号更新文件的内容.我遇到了一个名为text-file-operations的插件，但是与其编写一个新文件，不如我认为更新会更好.

When running my Jenkins build i need to update the contents of a file with a version number in this case. I have come across a plugin called text-file-operations but rather than write a whole new file I thought it would be better to update.

在此示例中，我在项目的根目录中有一个podspec文件，该文件只需要使用在过程中较早创建的变量更新版本号即可.

In this example I have a podspec file located in the root of the project which just needs a version number updated with a variable I have created earlier in the process.

spec.version               = '13.4.0'

我只需要将其转换为

spec.version               = "${VERSION_NUMBER}"

有没有办法做到这一点?

Is there a way to do this ?

推荐答案

这就是您想要的吗?

Groovy +如何在文件中附加文本(换行)

f = new File('<filename>')
f.append("spec.version               = ${VERSION_NUMBER}\n")
