maven-resources-plugin + 配置文件

Question

我正在将一个现有项目（遗留项目）移动到 Maven。它具有以下结构：

ParentProject
 - EARModule
   - src
   - target
   - pom.xml (ear)
 - WARModule
   - src
     - main
       - java
         - (java packages and classes)
       - resources
         - dev
           - index.jsp
         - prod
           - index.jsp
       - webapp
         - views
           - index.jsp (original)
         - WEB-INF
   - target
   - pom.xml (war)
 - pom.xml (parent)

我打算有两个不同的配置文件：生产和开发。在production profile中，/WARModule/src/main/resources/prod/index.jsp应该组装到views/war目录下。在开发配置文件中，/WARModule/src/main/resources/dev/index.jsp 应复制到 views/ war 目录中。

为此，我正在尝试使用我在 war pom.xml.

中配置的 maven-resources-plugin

<properties>
    <prodResourcesDir>${basedir}/src/main/resources/prod</prodResourcesDir>
    <devResourcesDir>${basedir}/src/main/resources/dev</devResourcesDir>
    <viewsDir>${basedir}/target/WARModule/views</viewsDir>
</properties>

正如您在上面看到的，我正在创建两个配置文件（生产和开发）并在每个配置文件下配置资源插件。

当我运行 mvn install -P any_of_the_profiles时，index.jsp没有复制到指定的目的地。相反，我得到了原始版本。谁能帮我解决这个问题？

Answer 1

我最终发现 maven-resources-plugin 适用于 resources，而不适用于 web resources (JSP).

所以我将方法切换为 maven-war-plugin filtering feature 并指定目标路径。因此，我网站 pom.xml 中的个人资料部分最终变成了这样：

<profiles>
    <profile>
        <id>development</id>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-war-plugin</artifactId>
                    <version>3.0.0</version>
                    <configuration>
                        <webResources>
                            <resource>
                                <directory>${devResourcesDir}</directory>
                                <filtering>true</filtering>
                                <targetPath>views</targetPath> <!-- target/WebModule/ subdirectory -->
                                <include>index.jsp</include>
                            </resource>
                        </webResources>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </profile>
    <profile>
        <id>production</id>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-war-plugin</artifactId>
                    <version>3.0.0</version>
                    <configuration>
                        <webResources>
                            <resource>
                                <directory>${prodResourcesDir}</directory>
                                <filtering>true</filtering>
                                <targetPath>views</targetPath> <!-- target/WebModule/ subdirectory -->
                                <include>index.jsp</include>
                            </resource>
                        </webResources>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </profile>
</profiles>

这告诉 maven-war-plugin 将 index.jsp 从指定的资源目录移动到 target/WebModule/views 目录。都是war插件在打包war之前完成的，所以不需要指定生命周期阶段。
