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?
How can I do this with Maven

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>
