Querydsl生成qclasses

Question

以下配置有什么问题？

           <plugin>
                <groupId>com.querydsl</groupId>
                <artifactId>querydsl-maven-plugin</artifactId>
                <version>4.1.4</version>
                <executions>
                    <execution>
                        <id>generate-query-dsl-classes</id>
                        <phase>compile</phase>
                        <goals>
                            <goal>jpa-export</goal>
                            <goal>compile</goal>
                        </goals>
                        <configuration>
                            <targetFolder>target/generated-sources/query_dsl/qclasses</targetFolder>
                            <packages>
                                <package>com.test.data.jpa.domain</package>
                            </packages>
                            <sourceFolder>target/generated-sources/query_dsl/qclasses</sourceFolder>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

问题是编译项目时QClasses既没有生成也没有编译，因为QClasses在代码中被引用，编译无法继续，正确的配置是什么？
