如何将Maven配置文件值注入属性文件 [英] How to inject Maven profile value into properties file

问题描述

有点卡在这里.我有一个带有3个配置文件的pom. Theese配置文件具有不同的版本名称.我要在构建特定配置文件时将该版本名称注入属性文件.

Little stuck here. I have a pom with 3 profiles. Theese profiles have different version name. I want to inject that version name into properties file when a specific profile is building.

我的个人资料:

<profiles>
    <profile>
        <id>dev</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <properties>
            <projectVersion>DEV</projectVersion>
        </properties>
    </profile>

    <profile>
        <id>test</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <properties>
            <projectVersion>1.0.0-RC1</projectVersion>
        </properties>
    </profile>

    <profile>
        <id>prod</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <properties>
            <projectVersion>1.0.0-Final</projectVersion>
        </properties>
    </profile>
</profiles>

和filter.properties看起来像这样:

and filter.properties looks like this:

projectName = defaultName
versionName = defaultVersion

该怎么做?我通过命令构建项目:

How to do that? Im building project by command:

mvn clean install -D profile_name

推荐答案

您需要做的是在POM文件的<build>部分中添加一个新部分.

What you need to do is to add a new section to your <build> section of your POM file.

赞:

<build>
    <resources>
        <resource>
            <filtering>true</filtering>
            <includes>
                <include>**/*.properties</include>
            </includes>
            <directory>src/main/resources</directory>
        </resource>
    </resources>
</build>

这将查找指定文件**/*.properties上指定文件夹(src/main/resources)的内部，并在遇到定义的变量时更改文件.

This will look inside the specified folder (src/main/resources) on the specified files **/*.properties and change the files when it encounters defined variables.

因此，要进行此项工作，您的属性文件必须采用以下方式:

So in order to this work your propertie file must be this way:

projectName = ${defaultName}
versionName = ${defaultVersion}

请注意这些变量的名称. Maven将用您定义的名称替换它，或者Maven结构的名称(例如$ {projectVersion})将被pom文件的<version>1.0</version>标记替换.

Be aware with these variables name. Maven will replace it with the defined names by you or the names of the Maven structure like ${projectVersion} will be replaced by the <version>1.0</version> tag of your pom file.

所以不要使用:

<properties>
     <projectVersion>1.0.0-Final</projectVersion>
</properties>

将此变量的名称(和版本)更改为其他名称，例如:

Change the name (and the version) of this variable to something else like:

<properties>
     <defaultVersion>1.0.0-Final</defaultVersion>
     <defaultName>someName</defaultName>
</properties>

在所有个人资料上.

然后只需以以下方式运行您的maven命令:

And just run your maven command as:

mvn install -Pprofilename
