使用 Maven 的环境变量

2022-01-15 00:00:00 environment-variables java maven

我已经将一个项目从 Eclipse 移植到 Maven，我需要设置一个环境变量来使我的项目工作.

I've ported a project from Eclipse to Maven and I need to set an environment variable to make my project work.

在 Eclipse 中，我转到运行 -"运行配置"并且，在环境"选项卡下，我设置了WSNSHELL_HOME".到值conf".

In Eclipse, I go to "Run -> Run configurations" and, under the tab "environment", I set "WSNSHELL_HOME" to the value "conf".

如何使用 Maven 做到这一点?

推荐答案

你可以直接在命令行传递，如

You can just pass it on the command line, as

mvn -DmyVariable=someValue install

[更新]请注意，参数的顺序很重要 - 您需要在命令之前指定任何选项.[/Update]

[Update] Note that the order of parameters is significant - you need to specify any options before the command(s).[/Update]

在 POM 文件中，您可以将系统变量(在命令行或 pom 中指定)称为 ${myVariable}，将环境变量称为 ${env.我的变量}.(感谢评论者的更正.)

Within the POM file, you may refer to system variables (specified on the command line, or in the pom) as ${myVariable}, and environment variables as ${env.myVariable}. (Thanks to commenters for the correction.)

好的，所以你想将你的系统变量传递给你的测试.如果 - 如我所料 - 你使用 Surefire 插件 进行测试，最好是在 pom 中指定所需的系统变量，在 plugins 部分，例如

OK, so you want to pass your system variable to your tests. If - as I assume - you use the Surefire plugin for testing, the best is to specify the needed system variable(s) within the pom, in your plugins section, e.g.

<build>
    <plugins>
        ...
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            ...
            <configuration>
                ...
                <systemPropertyVariables>
                    <WSNSHELL_HOME>conf</WSNSHELL_HOME>
                </systemPropertyVariables>
            </configuration>
        </plugin>
        ...
    </plugins>
</build>
