maven - 如何使用环境变量激活 Maven 配置文件？

Question

出于某种原因，我必须使用环境变量而不是将系统属性传递给 mvn 命令。因此，我使用 ${env.PROFILE} 作为属性名称， pom.xml 中的配置文件设置显示如下:

    <profiles>
        <profile>
            <id>dev</id>
            <activation>
                <activeByDefault>true</activeByDefault>
                <property>
                    <name>${env.PROFILE}</name>
                    <value>dev</value>
                </property>
            </activation>
            <properties>
                <profile.assembly.suffix></profile.assembly.suffix>
            </properties>
        </profile>
        <profile>
            <id>online</id>
            <activation>
                <property>
                    <name>${env.PROFILE}</name>
                    <value>online</value>
                </property>
            </activation>
            <properties>
                <profile.assembly.suffix>-online</profile.assembly.suffix>
            </properties>
        </profile>
    </profiles>

然后，我尝试将配置文件激活为在线，但失败了，命令行显示如下:

E:\Tetris\src\1_Branches\rtm_tetris_zhugan\Server\LobbyServer>set PROFILE=online
E:\Tetris\src\1_Branches\rtm_tetris_zhugan\Server\LobbyServer>echo %PROFILE%
online

E:\Tetris\src\1_Branches\rtm_tetris_zhugan\Server\LobbyServer>mvn help:active-profiles

然后我打开maven Debug模式(-X)，属性如下:

我们可以在上面的属性列表中找到属性:

env.PROFILE=online, profile.assembly.suffix=,

似乎在环境中设置了“PROFILE”变量。但是，“在线”配置文件未激活。有什么问题？谢谢。

Answer 1

替换 <name>${env.PROFILE}</name>至 <name>env.PROFILE</name>并尝试运行 mvn help:active-profiles ，您应该获得在线个人资料。

C:\Sachin\data\development\app_code\spring-security-demo>mvn help:active-profiles

The following profiles are active:

 - online (source: com.security.example:spring-security-demo:0.0.1-SNAPSHOT)

以下是更新的个人资料标签

        </activation>
        <properties>
            <profile.assembly.suffix>-online</profile.assembly.suffix>
        </properties>
    </profile>
</profiles>

您也可以使用 mvn help:all-profiles这将列出所有具有事件状态的配置文件。例如。对于您的示例，如果我们已将 PROFILE 值设置为在线运行 mvn help:all-profiles应显示如下

我使用 maven 3.2.5 对其进行了测试在 Windows 10 操作系统中。
