Solution

you need plugin, try this:

                <plugin>
                    <groupId>com.mysema.maven</groupId>
                    <artifactId>maven-apt-plugin</artifactId>
                    <version>1.0.4</version>
                    <executions>
                        <execution>
                            <id>process-common-model</id>
                            <goals>
                                <goal>process</goal>
                            </goals>
                            <phase>generate-sources</phase>
                            <configuration>
                                <sourceDirectory>${project.build.directory}/{yourSourceDir}</sourceDirectory>
                            </configuration>
                        </execution>
                    </executions>
                    <configuration>
                        <outputDirectory>target/generated-sources/querydsl</outputDirectory>
                        <processors>
                            <processor>com.mysema.query.apt.jpa.JPAAnnotationProcessor</processor>
                        </processors>
                        <options>
                            <querydsl.entityAccessors>true</querydsl.entityAccessors>
                            <querydsl.createDefaultVariable>true</querydsl.createDefaultVariable>
                            <querydsl.packageSuffix>.qdsl</querydsl.packageSuffix>
                        </options>
                    </configuration>
                </plugin>

I copied this from my project. just added it to your pom and have a try.

There are additional options in the code above, if you just wanna a simple one, focus on the querydsl reference

after generating the Q-files and using them in project if by mistake those files got deleted then will it compile again( as mvn clean install will also fail.)

Adding the plugins alone won't do anything, you need to run mvn clean install
