如何根据操作系统在maven中设置环境变量

Question

我对maven相当新鲜.我已经设置了一个pom.xml,它定义了运行我的单元测试的配置文件.我正在尝试设置Path环境变量.env变量名称是Windows的路径和Linux的LD_LIBRARY_PATH.我不想继续改变这些环境.变量名取决于操作系统.我该怎么做到这一点？

<profile>
        <id>integration-tests</id>
        <build>
         <plugins>
            <plugin>
                <groupId>org.eclipse.tycho</groupId>
                <artifactId>tycho-surefire-plugin</artifactId>
                <version>${tychoVersion}</version>
                <configuration combine.self="override">
                    <argLine>${tycho.testArgLine} ${global.test.vmargs} ${bundle.test.vmargs}</argLine>
                    <forkMode>${bundle.test.forkMode}</forkMode>
                    <useUIHarness>${bundle.test.useUIHarness}</useUIHarness>
                    <useUIThread>${bundle.test.useUIThread}</useUIThread>
                    <environmentVariables>
                      <!--For windows change LD_LIBRARY_PATH to PATH-->
                        <LD_LIBRARY_PATH>${dependenciesDir}${path.separator}{env.LD_LIBRARY_PATH}</LD_LIBRARY_PATH>

                    </environmentVariables>
                </configuration>
            </plugin>
        </plugins>
        </build>

    </profile>

配置文件激活可能有帮助.<environmentVariables>从集成测试配置文件中删除配置.然后添加下面的配置文件,调整<activation>部分以满足特定要求.您无需在命令行上显式启用这些配置文件; Maven将根据运行构建的系统激活正确的配置文件.

<profile>
  <id>windows-tests</id>
  <activation>
      <os>
        <family>Windows</family>
      </os>
  </activation>
  <build>
     <plugins>
        <plugin>
            <groupId>org.eclipse.tycho</groupId>
            <artifactId>tycho-surefire-plugin</artifactId>
            <version>${tychoVersion}</version>
            <configuration>
                <environmentVariables>
                    <PATH>${dependenciesDir}${path.separator}{env.PATH}</PATH>
                </environmentVariables>
            </configuration>
        </plugin>
    </plugins>
    </build>
</profile>
<profile>
  <id>linux-tests</id>
  <activation>
      <os>
        <family>Linux</family>
      </os>
  </activation>
  <build>
     <plugins>
        <plugin>
            <groupId>org.eclipse.tycho</groupId>
            <artifactId>tycho-surefire-plugin</artifactId>
            <version>${tychoVersion}</version>
            <configuration>
                <environmentVariables>
                    <LD_LIBRARY_PATH>${dependenciesDir}${path.separator}{env.LD_LIBRARY_PATH}</LD_LIBRARY_PATH>

                </environmentVariables>
            </configuration>
        </plugin>
    </plugins>
    </build>
</profile>
