q classes are not generated in querydsl

Question

I am developping a java/jee application using spring boot as framework and i want to filter entity application,so i tried to use querydsl and now i am trying to generate Q classes of querydsl.But when i make mvn install Q classes are not generated.i am using eclipse neon as ide and and java home is configured to JDK 8. I am using jpa 2 and hibernate 5.
This is my code:

package biz.picosoft.entities;

Answer 1

Your configuration seems right.

Try this from Querydsl's documentation

If you use Eclipse, run mvn eclipse:eclipse to update your Eclipse project to include target/generated-sources/java as a source folder.

Now you are able to construct JPA query instances and instances of the query domain model.

You may also try Patrick's solution .
