java - 找不到符号 - Spring Boot Maven 同级作为依赖项

Question

使用 Maven spring boot 插件重新打包没有帮助。

1. 尝试清理 .m2 文件夹。
2. 通过 sts 和命令行构建项目。
3. 添加了组件扫描器来扫描实体，但在 Maven 构建本身时失败。
4. 添加了 Spring Boot Maven 插件以重新打包为可执行 jar 选项，但似乎没有任何帮助。

父pom包含spring boot启动器

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.6.RELEASE</version>
    <relativePath /> <!-- lookup parent from repository -->
  </parent>

以及以下模块

<modules>
    <module>client-data</module>
    <module>eureka-server</module>
    <module>eureka-client-service-1</module>
    <module>eureka-client-service-2</module> 
 </modules>

eureka-client-service-1和eureka-client-service-2有client-data作为依赖。

自 client-data是 spring-boot包类型项目jar ，添加了以下代码来创建 uber jar在客户端数据的pom.xml中

     <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                        <configuration>
                            <classifier>exec</classifier>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

还在做mvn clean install -amd -e最终出现以下错误

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project eureka-client-service-1: Compilation failure: Compilation failure:

Answer 1

对于“有什么方法可以在不改变项目结构的情况下删除 spring-boot 行为。”的问题

=> 您可以覆盖子 pom 文件中的 spring-boot-maven-plugin 行为。

引用这里:How to add a dependency to a Spring Boot Jar in another project?

Spring Boot 1.x

  <plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <version>1.5.20.RELEASE</version>
    <executions>
      <execution>
        <goals>
          <goal>repackage</goal>
        </goals>
        <configuration>
          <classifier>exec</classifier>
        </configuration>
      </execution>
    </executions>
    ...
  </plugin>

Spring Boot 2.x如果您使用的是 spring-boot-starter-parent，则重新打包目标会在带有 id repackage 的执行中自动执行。在该设置中，只需指定配置，如以下示例所示:

  <plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <executions>
      <execution>
        <id>repackage</id>
        <configuration>
          <classifier>exec</classifier>
        </configuration>
      </execution>
    </executions>
    ...
  </plugin>
