如何在maven中调用exec：java插件时传递systemProperties？ [英] How to pass systemProperties when invoking exec:java plugin in maven?

问题描述

我想使用exec：java插件从命令行调用主类。我可以使用 -Dexec.args =arg0 arg1 arg2从命令行传递参数，我不知道如何传递系统属性。我试过'-Dexec.systemProperties =key = value`但没有效果。

I want to use the exec:java plugin to invoke the main class from command line. I can pass arguments from the command line using -Dexec.args="arg0 arg1 arg2", I don't know how to pass system properties. I tried '-Dexec.systemProperties="key=value"` but with no effect.

pom.xml 看起来像这样：

  <plugin>  
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <configuration>
      <mainClass>ibis.structure.Structure</mainClass>
    </configuration>  
  </plugin>

推荐答案

无法设置< systemProperties> 参数在命令行上。

There is no way to set the <systemProperties> parameter on the command line.

但是，由于 exec：java 未分叉，你可以通过maven的系统属性，它也会被 exec：java 选中。

However, since exec:java is not forked, you can just pass a system property to maven and it will be picked up by exec:java as well.

mvn -Dkey=value exec:java -Dexec.mainClass=com.yourcompany.yourclass \
    -Dexec.args="arg1 arg2 arg3"
