Maven多模块项目包装错误

时间：2018-12-04 09:43:25

标签： java spring-boot maven-3 spring-boot-maven-plugin

我正在尝试使用Maven开发多模块项目。但是，当我想打包项目时，就会出错。

它表示程序包在Web类中不存在。我已经在“问与答”部分尝试过解决方案。但是没有用。您可以查看我的仓库并告诉我我做错了什么吗？

答案 0 :(得分：1)

我通过将此数据添加到数据pom来弄清楚

   <properties>
    <spring-boot.repackage.skip>true</spring-boot.repackage.skip>
   </properties>

但是我不知道为什么它解决了我的问题。

答案 1 :(得分：0)

项目结构有问题。由于您的反应堆父级的父级工件是

LayerList

所有工件，包括<groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.0.RELEASE</version> 模块工件都将执行此插件执行：

data

<plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <executions> <execution> <id>repackage</id> <goals> <goal>repackage</goal> </goals> </execution> </executions> <configuration> <mainClass>${start-class}</mainClass> </configuration> </plugin> 模块不应重新包装到胖子罐中，因为您不想将其作为Spring Boot应用程序执行。您想将其用作依赖项。

请勿将data用作反应堆父对象！而是将Spring Boot BOM导入您父母的spring-boot-starter-parent（更多here）中：

dependencyManagement

将此添加到父母的<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> <version>2.1.0.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> ：

pluginManagement

将<plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version>2.1.0.RELEASE</version> </plugin> 的发票从您的父级移动到spring-boot-maven-plugin模块，这样仅web将被重新打包，而web则不会。

最后，从父目录调用data。 {@ {1}}是反应堆运行所必需的，因为必须将依赖项工件（mvn clean install）复制到本地Maven存储库（通常为install），然后才能被依赖项工件用作依赖项。 data-0.0.1-SNAPSHOT.jar模块。
