如何通过环境变量传递Maven设置 [英] How to pass Maven settings via environmental vars

问题描述

在我们的setting.xml文件中，我们具有以下内容:

In our setting.xml file we have the following:

<servers>
    <server>
      <id>deploymentRepo</id>
      <username>repouser</username>
      <password>repopwd</password>
    </server>
</servers>

是否可以通过环境变量而不是settings.xml传递这些设置(或等效设置)?

Would it be possible to pass those settings (or their equivalent) via environmental variables instead of the settings.xml?

推荐答案

是的，您可以通过两种方式做到这一点:

Yes, you can do this in two ways:

• 在命令行中使用变量传递属性.例如，您可以在settings.xml中使用以下内容:

• passing properties in command line, using variables. For example, you can use in your settings.xml something like this:

<servers>
    <server>
      <id>deploymentRepo</id>
      <username>${server.username}</username>
      <password>${server.password}</password>
    </server>
</servers>

然后在命令行中，通过以下方式传递这些变量:

And in command line, pass these variables in this way:

mvn clean package -Dserver.username=yourusername -Dserver.password=yourpassword

• 导出环境属性.例如，如果导出(在Linux中，类似于export SERVER_USERNAME=yourusername之类的)SERVER_USERNAME和SERVER_PASSWORD变量，则可以这样使用:
• exporting environments properties. For example, if you export (in linux, something like export SERVER_USERNAME=yourusername) SERVER_USERNAME and SERVER_PASSWORD variables, you can use like this:

<servers>
    <server>
      <id>deploymentRepo</id>
      <username>${env.SERVER_USERNAME}</username>
      <password>${env.SERVER_PASSWORD}</password>
    </server>
</servers>
