如何在构建步骤之前将机密添加到 application.properties 文件

Question

我正在使用 GitHub Actions CI/CD 工作流程来自动执行构建、测试和部署步骤。为了成功构建项目，我需要包含一个秘密变量（在设置中定义）以写入 application.properties 文件。但是，在构建时在文件中找不到该变量。这是工作流程 yml 文件

如果您想将变量作为新行写入属性，请将变量放在“”内。

echo "$PropertyString" >> path/file.properties

字符“>>”将在文档末尾写入第一部分（作为新行）

如果你想用你的内容替换文件内容，你必须使用：

echo $Property > path/file.properties

这将用定义的属性替换所有文件内容

在命令运行之前，变量会被替换为其名称。我建议您阅读 echo 命令文档
