Spring Data JPA - Specifications and Querydsl

Question

I'm trying to integrate QueryDSL to my existing project with Spring Data, I've tried different samples and now I've decided to stick to this one Advanced Spring Data JPA - Specifications and Querydsl.

Problem: when I run the project as Maven generate-sources I get this error

error: Annotation processor 'com.mysema.query.apt.jpa.JPAAnnotationProcessor' not found 

I'm adding this plugin to my pom.xml as the blog post indicates:

<plugin>   <groupId>com.mysema.maven</groupId>   <artifactId>maven-apt-plugin</artifactId>   <version>1.0</version>   <executions>     <execution>       <phase>generate-sources</phase>       <goals>         <goal>process</goal>       </goals>       <configuration>         <outputDirectory>target/generated-sources</outputDirectory>         <processor>com.mysema.query.apt.jpa.JPAAnnotationProcessor</processor>       </configuration>     </execution>   </executions> </plugin> 

and the dependency:

<dependency>      <groupId>com.mysema.querydsl</groupId>      <artifactId>querydsl-sql</artifactId>      <version>3.6.9</version> </dependency> 

Can anyone point me in the right direction on how to solve this or how to properly integrate QueryDSL to my project ? Thanks in advance!

Answer 1

The way I could make this work was using the com.querydsl.apt.jpa.JPAAnnotationProcessor instead of the com.mysema.query.apt.jpa.JPAAnnotationProcessor and by changing the dependencies as follow:

<dependency>   <groupId>com.querydsl</groupId>   <artifactId>querydsl-apt</artifactId>   <version>4.0.6</version> </dependency> <dependency>   <groupId>com.querydsl</groupId>   <artifactId>querydsl-jpa</artifactId>   <version>4.0.6</version> </dependency> 

The plugin end up like this:

<plugin>   <groupId>com.mysema.maven</groupId>   <artifactId>apt-maven-plugin</artifactId>   <version>1.1.3</version>   <executions>     <execution>       <phase>generate-sources</phase>       <goals>         <goal>process</goal>       </goals>       <configuration>         <outputDirectory>${project.build.directory}/generated-sources</outputDirectory>          <processor>com.querydsl.apt.jpa.JPAAnnotationProcessor</processor>       </configuration>     </execution>   </executions> </plugin> 

I also executed in the command line at the projects root mvn eclipse:eclipse to update Eclipse to include the generated sources.

Update:

Replaced the plugin maven-apt-plugin for apt-maven-plugin and changed version to 1.1.3
