Generate QueryDsl Q Classes From Package

Question

How do I generate QueryDsl Q-Classes by only specifying a package name? Given the source classes reside in my target/generated-sources folder since they are the product of other build plugins (WSDLs, XSDs, etc.)

I have tried using the following plugins, but can't find the right configuration:

<groupId>com.mysema.querydsl</groupId>
<artifactId>querydsl-maven-plugin</artifactId>
<version>2.9.0</version>
<executions>
    <phase>generate-sources</phase>
    <goals>
        <goal>process</goal>
    </goals>
    <configuration>
        <outputDirectory>target/generated-sources</outputDirectory>
        <processor>${com.mysema.query.apt.ProcessorClass}</processor>
    </configuration>
</executions>

and:

<groupId>com.mysema.maven</groupId> 
<artifactId>maven-apt-plugin</artifactId> 
<version>1.0.4</version> 

What I'd like to do is something like this:

<configuration>
    <packageName>com.my.package</packageName>
    <sourceFolder>target/generated-sources</sourceFolder>
    <targetFolder>target/generated-sources/querydsl</targetFolder>
</configuration>

...which would generate the classes:

• com.my.package.QFoo.java
• com.my.package.QBar.java

Since there's no common JPA or JDO annotation, and I don't have have access to the source files, I haven't been able to use any of the com.mysema.query.apt.*Processor s for the maven-apt-plugin's <processor> .

added full maven-apt-plugin configuration. 添加了完整的maven-apt-plugin配置。

- I was able to get the maven-apt-plugin to work sporadically via the maven command line, but not Eclipse/STS by extending AbstractQuerydslProcessor to look for @XmlType -annotated classes. - 我能够通过maven命令行偶尔使用maven-apt-plugin工作，但不是通过扩展AbstractQuerydslProcessor来查找@XmlType -annotated类，而不是Eclipse / STS。 Double code-generation is admittedly not an ideal solution.

Answer 1

The answer is to generate the Q-classes using the strategy Timo outlined here: https://github.com/mysema/querydsl/issues/196

In my module's package-info.java :

@QueryEntities({ com.remote.module.Foo.class,
    com.remote.module.Bar.class })
package com.my.local.module.querydsl;

import com.mysema.query.annotations.QueryEntities;

The plugin execution in the Maven POM:

<plugin>
    <groupId>com.mysema.maven</groupId>
    <artifactId>apt-maven-plugin</artifactId>
    <executions>
        <execution>
            <id>apt-maven-plugin-remote-module-QuerydslAnnotationProcessor</id>
            <goals>
                <goal>process</goal>
            </goals>
            <configuration>
                <outputDirectory>target/generated-sources</outputDirectory>
                <showWarnings>true</showWarnings>
                <!-- genereate Q-classes specified in package-info.java -->
                <processor>com.mysema.query.apt.QuerydslAnnotationProcessor</processor>
            </configuration>
        </execution>
    </executions>
    <dependencies>
        <dependency>
            <groupId>com.mysema.querydsl</groupId>
            <artifactId>querydsl-apt</artifactId>
        </dependency>
    </dependencies>
</plugin>
