使用配置文件属性进行Maven资源过滤

Question

我有以下pom.xml:

<project
    xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>mycompany</groupId>
    <artifactId>resource-fail</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <properties>
        <foo.bar>BazBat</foo.bar>
    </properties>
    <build>
        <resources>
            <resource>
                <filtering>true</filtering>
                <directory>src/main/resources</directory>
            </resource>
        </resources>
    </build>
    <profiles>
        <profile>
            <id>Development</id>
            <!--
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
            -->
            <properties>
                <foo.bar>Development</foo.bar>
            </properties>
        </profile>
    </profiles>
</project>

请注意,该activation元素已profile被注释掉

我也有以下内容 src/main/java/application.properties

myproperty=${foo.bar}

因此,我希望Maven的做的仅仅是更换${foo.bar}用BazBat,除非发展轮廓activiated,那么我期待Maven来代替${foo.bar}与Development

当我运行mvn package它时,将值设置为BazBat.好,资源过滤按预期工作.

但是,当我运行mvn package -P Development它时,将值设置为BazBat

为了进一步混淆,如果取消注释activation配置文件中的元素并运行mvn package它将设置${foo.bar}为Development

我甚mvn help:active-profiles package至跑来让它输出活动的配置文件名称,并且在上面的两个场景中它都说开发配置文件是活动的,但是如果没有activeByDefault设置标志,过滤仍然不起作用.

总结一下:

• 如果配置文件是,Maven会使用配置文件中的值正确覆盖属性 activeByDefault
• Maven的也没有,如果我通过命令行开关启动配置文件重写属性

到底是怎么回事？

我的环境:

> mvn -version
Apache Maven 3.2.5 (12a6b3acb947671f09b81f49094c53f426d8cea1; 2014-12-14T11:29:23-06:00)

更新: 我已升级到最新的maven(3.3.3) - 问题仍然存在.我的新环境:

Answer 1

执行时需要去掉-P和development之间的空格：mvn package -PDevelopment
