[Brandon Lamb]

Hello, I am trying to see if I am doing something obviously dumb. I've tried both 2.2.4 and 3.1.0 of the maven-processor-plugin. I have not tried a different version of mapstruct yet.

[INFO] --- maven-processor-plugin:2.2.4:process (process) @ order ---

Doesn't look suspicious... The warning originates from javac, which is called by the processor plugin. Are there maybe no sources to compile?

Anyway, there is something else you could try instead of using the processor-maven-plugin. Use the latest version of the maven-compiler-plugin and add the mapstruct-processor to the annotationProcessorPath there:

 <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.5.1</version>
    <configuration>
        <annotationProcessorPaths>
            <path>

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

            </path>
        </annotationProcessorPaths>
        <compilerArgs>
            <arg>-Amapstruct.suppressGeneratorTimestamp=true</arg>
            <arg>-Amapstruct.defaultComponentModel=cdi</arg>
        </compilerArgs>
    </configuration>
</plugin>

Note on IDE support: If you use Eclipse, you might need to update the m2e-apt plugin to 1.2.0 for it to pick up the configuration correctly. On NetBeans, it works out of the box anyway. For IntelliJ, you'd have to configure the Annotation-Processing manually anyway.

Hope it helps,

Andreas

Thanks for the tip, I'll try that. I also came across a mapstruct + lombok thread so looks like I will have other issues to work out now anyway.

Hi Brandon,

For the default component model, I recommend to make use of a @MapperConfig class for configuring this (see http://mapstruct.org/documentation/1.1/reference/html/index.html#shared-configurations). In hindsight, the processor options should have only been added for stuff like "suppressGenerationTimestamp" etc.
