环境变量与Maven [英] Environment Variable with Maven

问题描述

在Eclipse中，我去运行 - >运行配置，在环境选项卡下，将WSNSHELL_HOME设置为值conf。

如何使用Maven？ / p>

非常感谢！

解决方案

命令行作为

  mvn -DmyVariable = someValue install 
  

[更新] 请注意，参数的顺序很重要 - 您需要在之前指定任何选项 s）。

在POM文件中，您可以参考系统变量（在命令行中指定或在pom）作为 $ {myVariable} ，环境变量为 $ {env.myVariable} 。

Update2

你想将你的系统变量传递给你的测试。如果我假设 - 你使用 Surefire插件进行测试，最好的是在您的插件部分中指定pom内所需的系统变量，例如

 <建立> 
< 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> 
  

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

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

How can I do this with Maven?

Thank you very much!

解决方案

You can just pass it on the command line, as

mvn -DmyVariable=someValue install

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

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.)

Update2

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>
