一次使用不同的分类器构建多个工件 [英] Build multiple artifacts with different classifiers at once

问题描述

W希望我的Maven项目一次生成具有不同分类器的三个工件.我知道我可以用模块等生成它.这实际上是一个资源项目，我想为DEV，STAGE和PROD环境生成配置.

W want my maven project to produce three artifacts with different classifiers at once. I know that I can produce it with modules etc. This is actually a resources project that I want to produce configuration for DEV, STAGE and PROD environment.

我要运行一次mvn:install，并在回购中包含my.group:resources:1.0:dev，my.group:resources:1.0:stage和my.group:resources:1.0:prod.

What I want to have is to run mvn:install once and have my.group:resources:1.0:dev, my.group:resources:1.0:stage and my.group:resources:1.0:prod in my repo.

推荐答案

如果您指定多个插件执行并且

This can be done without profiles if you specify multiple plugin executions and resource filtering.

为${basedir}/src/main/filters中的每个版本创建一个属性文件(例如prod.properties，dev.properties)，并为每个环境保存适当的值.

Create a properties file for each version in ${basedir}/src/main/filters (e.g. prod.properties, dev.properties) holding appropriate values for each environment.

打开对资源的过滤:

<resources>
  <resource>
    <directory>src/main/resources</directory>
    <filtering>true</filtering>
  </resource>
</resources>

现在添加资源插件执行.请注意不同的过滤器文件和输出目录.

Now add the resource plugin executions. Note the different filter file and output directory.

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-resources-plugin</artifactId>
  <executions>
    <execution>
      <id>default-resources</id>
      <phase>process-resources</phase>
      <goals>
        <goal>resources</goal>
      </goals>
      <configuration>
        <outputDirectory>${project.build.outputDirectory}/dev</outputDirectory>
        <filters>
          <filter>${basedir}/src/main/filters/dev.properties</filter>
        </filters>
      </configuration>
    </execution>
    <execution>
      <id>prod</id>
      <phase>process-resources</phase>
      <goals>
        <goal>resources</goal>
      </goals>
      <configuration>
        <outputDirectory>${project.build.outputDirectory}/prod</outputDirectory>
        <filters>
          <filter>${basedir}/src/main/filters/prod.properties</filter>
        </filters>
      </configuration>
    </execution>
  </executions>
</plugin>

最后，jar插件；笔记分类器和输入目录:

Finally, the jar plugin; note classifier and input directory:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-jar-plugin</artifactId>
  <executions>
    <execution>
      <id>default-jar</id>
      <phase>package</phase>
      <goals>
        <goal>jar</goal>
      </goals>
      <configuration>
        <classifier>dev</classifier>
        <classesDirectory>${project.build.outputDirectory}/dev</classesDirectory>
      </configuration>
    </execution>
    <execution>
      <id>jar-prod</id>
      <phase>package</phase>
      <goals>
        <goal>jar</goal>
      </goals>
      <configuration>
        <classifier>prod</classifier>
        <classesDirectory>${project.build.outputDirectory}/prod</classesDirectory>
      </configuration>
    </execution>
  </executions>
</plugin>

运行mvn clean install应该使用所需的dev和prod分类器在工件中生成经过适当过滤的资源.

Running mvn clean install should produce the properly filtered resources in artifacts with dev and prod classifiers like you want.

在示例中，对于开发版本，我使用了default-resources和default-jar的执行ID.如果没有此功能，则在构建时也会得到未分类的jar工件.

In the example, I used execution IDs of default-resources and default-jar for the dev versions. Without this you would also get an unclassified jar artifact when you build.
