Maven - 在主模块中运行子模块的插件任务

Question

我有一个maven项目（java web backend）设置了一个子模块，该子模块使用JSweet将我的java源代码转换为javascript文件（前端）。

我的目标是将所有子模块的源转换到文件夹“src / main / java / views / script”，其中主模块从中加载javascript文件。

这就是子模块的pom看起来的样子：

                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

</project>

我已将此子模块添加到主项目的依赖项中：

    <dependency>
        <groupId>com.domain</groupId>
        <artifactId>domain-frontend</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>

现在我希望前端的JSweet插件任务在主模块中作为插件运行，以便在重新加载Web服务器时转换源。我怎样才能做到这一点？

Answer 1

我通过以下方式让这个工作：

1）创建一个新的Maven项目
2）将后端和前端添加为模块，如下所示：

<modules>
    <module>frontend</module>
    <module>backend</module>
</modules>

在前端和后端注册父项目：

<parent>
    <artifactId>domain-webapp</artifactId>
    <groupId>com.domain.webapp</groupId>
    <version>1.0-SNAPSHOT</version>
</parent>

现在每当我做

mvn package ninja:run -pl backend

它首先调用前端的插件，将Java源代码编译为Javascript文件，然后编译后端。

ninja:run任务（来自我的框架）在文件被更改时自动重建，这就是为什么对我来说重要的是JSweet文件也被重新传输。

由于ninja:run仅为后端模块所知，我必须使用-pl backend。

希望我能帮助别人！

Answer 2

为了在webapp中使用您的子模块，您可以将前端项目/模块打包为JSweet糖果，以便在后端项目中将其作为糖果依赖项引用。这个主题在这里部分解释： https://github.com/cincheo/jsweet/blob/v1.1.1/doc/jsweet-language-specifications.md#packaging-a-jsweet-jar-candy

我给你以下适用于我的Maven配置。

前端项目pom

后端项目pom

Candy在依赖项中被引用并提取到 src/main/webapp/js/candies 它仍然是手动的，您必须构建您的糖果，然后您的后端使用重新部署 mvn clean generate-sources -P client 您可以删除个人资料，我认为这对您没用

NB：在你的情况下，将前端直接放在你的web项目中可能会更好，请注意，在我们的pom中，有2个源目录：src / main / java和src / main / jsweet ，它可能是一个解决方案。这对我来说很有意义，前端JSweet源代码类似于Javascript资源，它们位于webapp中：）
