我正在尝试让 QueryDSL 参与 Spring Roo 项目。

这是我的插件配置：

        <plugin>
            <groupId>com.mysema.maven</groupId>
            <artifactId>maven-apt-plugin</artifactId>
            <version>1.0.2</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>

当我运行以下命令时：mvn apt:process，我收到以下错误：

当然，我已经尝试过 mvn install ，它不会生成任何源。

欢迎任何建议。

编辑： maven-apt-plugin 的唯一输出是：

[INFO] --- maven-apt-plugin:1.0.2:process (default) @ suivitrc ---

您直接调用目标。在这种情况下不使用执行配置。运行全新安装时是否遇到相同的异常？
