解决ClassNotFoundException: Cannot find implementation for xxx?（环境：Mapstruct、Lombok、Maven 和 Eclipse）

一、环境：

Eclipse version:2021-06. ( lasted version)
lombok version:1.18.20 ( lasted version)
m2e-apt:1.5.3 ( lasted version)

二、安装好m2e-apt plugin 好，进行配置

三、pom配置：

 <properties>
        <!-- automatically run annotation processors within the incremental compilation -->
          <m2e.apt.activation>jdt_apt</m2e.apt.activation>
    </properties>

       <dependency>
            <groupId>org.mapstruct</groupId>
            <artifactId>mapstruct-jdk8</artifactId>
            <version>${mapstruct.version}</version>
        </dependency>
        <dependency>
            <groupId>org.mapstruct</groupId>
            <artifactId>mapstruct-processor</artifactId>
            <version>${mapstruct.version}</version>
        </dependency>

不建议有

<!-- <plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
<annotationProcessorPaths>
<path>
<groupId>org.mapstruct</groupId>
<artifactId>mapstruct-processor</artifactId>
<version>${mapstruct.version}</version>
</path>
<path>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
</path>
</annotationProcessorPaths>
</configuration>
</plugin> -->
