我正在尝试用maven开发多模块项目。但是当我想要打包我的项目时，它会产生错误。

它说web类中不存在包。我已经试过了问答部分的解决方案。但没有起作用。你能不能回顾一下我的回购记录，告诉我我做错了什么？

我通过向数据pom添加以下内容来解决这个问题

这个项目的结构有问题。因为您的反应堆父级的父工件是

代码语言：javascript
复制
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.0.RELEASE</version>

所有工件，包括data模块工件，都将执行此插件执行：

代码语言：javascript
复制
<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>

不应该将data模块重新打包到一个胖jar中，因为您不希望将它作为Spring应用程序执行。您希望将其用作依赖工件。

不要使用spring-boot-starter-parent作为反应堆的父级！相反，将Spring导入父dependencyManagement (更多这里)：

代码语言：javascript
复制
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-dependencies</artifactId>
    <version>2.1.0.RELEASE</version>
    <type>pom</type>
    <scope>import</scope>
</dependency>

将其添加到父pluginManagement中

代码语言：javascript
复制
<plugin>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-maven-plugin</artifactId>
  <version>2.1.0.RELEASE</version>
</plugin>

将spring-boot-maven-plugin调用从父模块移动到web模块，这样只有web才会被重新打包，data不会被打包。

最后，从父目录调用mvn clean install。install是反应堆工作所必需的，因为依赖工件(data-0.0.1-SNAPSHOT.jar)必须复制到本地Maven存储库(通常是~/.m2/repositories/...)，然后才能被web模块用作依赖项。
