java - 如何通过 maven-compiler-plugin 使用多个注释处理器

Question

我有一个 Spring Boot 项目，它有 lombok 和 mapstruct 并使用 Maven 作为构建工具。我需要在编译时处理注释，并将生成的源代码与最终的 jar 一起打包。构建成功。然而，最终的 jar 缺少 mapstruct 实现类。当我尝试启动 Spring Boot 应用程序时出现错误:

---

APPLICATION FAILED TO START

Description:

Field salesforceObjectMapper in com.some_org.service.salesforce.object.processor.SalesforceObjectProcessor required a bean of type 'com.some_org.service.salesforce.object.mapper.SalesforceObjectMapper' that could not be found.

Action:

Consider defining a bean of type 'com.some_org.service.salesforce.object.mapper.SalesforceObjectMapper' in your configuration.

这是我的 maven-compiler-plugin 设置:

<plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.7.0</version>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
        <annotationProcessorPaths>
            <path>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <version>1.18.12</version>
            </path>
            <path>
                <groupId>org.mapstruct</groupId>
                <artifactId>mapstruct-processor</artifactId>
                <version>1.2.0.Final</version>
            </path>
        </annotationProcessorPaths>
        <compilerArgs>
            <compilerArg>-Amapstruct.suppressGeneratorTimestamp=true</compilerArg>
            <compilerArg>-Amapstruct.suppressGeneratorVersionInfoComment=true</compilerArg>
        </compilerArgs>
    </configuration>
</plugin>

最终通过在编译阶段使用执行覆盖默认编译目标来解决此问题，如下所示:

<plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.7.0</version>
    <executions>
        <execution>
            <id>Compile With Annotation Processing</id>
            <phase>compile</phase>
            <goals>
                <goal>compile</goal>
            </goals>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <annotationProcessorPaths>
                    <path>
                        <groupId>org.projectlombok</groupId>
                        <artifactId>lombok</artifactId>
                        <version>1.18.12</version>
                    </path>
                    <path>
                        <groupId>org.mapstruct</groupId>
                        <artifactId>mapstruct-processor</artifactId>
                        <version>1.2.0.Final</version>
                    </path>
                </annotationProcessorPaths>
                <compilerArgs>
                    <compilerArg>-Amapstruct.suppressGeneratorTimestamp=true</compilerArg>
                    <compilerArg>-Amapstruct.suppressGeneratorVersionInfoComment=true</compilerArg>
                </compilerArgs>
            </configuration>
        </execution>
    </executions>
</plugin>
