How to use "-Amapstruct.defaultComponentModel=spring" in POM

[sheka...@gmail.com]

Hi,

I have used @Mapper(componentModel = "spring") to inject mapper object in my application and successfully mapped my DTO to entities.But when i was trying to configure through cofiguration options instead of using @Mapper(componentModel = "spring") getting exception as "invalid flag : -Amapstruct.defaultComponentModel=spring".

Could you please let me know if i was passing wrong processor option.

Thanks.

Hi Shekar,

that highy depends on how you are configuring the annotation-processing in the pom and where in the configuration you've added the parameter.

But based on the error message, I'd say that you just have to remove the "-A" prefix in your case.

If that doesn't do the trick, please give us a snippet of the related plugin configuration in your pom.

That said, I'd rather recommend you use a @MapperConfig class [1] for
configuring the component model in a single place.

In hindsight, that processor option should not have been added and it
may be a candidate for removal in a future version.

Thank you Andreas, as you suggested i have tried by removing "-A" prefix but still getting same error.Below is the snippet of plugin configuration.

<build>

<plugins>

<plugin>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-maven-plugin</artifactId>

</plugin>

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-compiler-plugin</artifactId>

<version>3.5.1</version>

<configuration>

<source>1.8</source>

  <target>1.8</target>

  <annotationProcessorPaths>

  <path>

  <groupId>org.mapstruct</groupId>

<artifactId>mapstruct-processor</artifactId>

<version>1.1.0.Final</version>

  </path>

  </annotationProcessorPaths>

                        <compilerArgs>

  <compilerArg>

  -Amapstruct.defaultComponentModel=spring

  </compilerArg>  

  </compilerArgs>

  </configuration>

</plugin>

</plugins>

</build>

Thanks,

Shekar.

Shekar,

I just tried it out myself and for me it's working. What JDK do you use? If it's a more or less up-to-date Oracle JDK 1.8 version, and this blocks you from anything, then we'd need a small sample project to reproduce and dig in further.

What Gunnar said is true, though - configuring the component model should be done using the annotations, and if that's not too much hassle for you our recommendation would be to use the @MapperConfig for this particular setting -- we didn't have the @MapperConfig annotation back when the component models were introduced, I think... :)
