【问题描述】：
我正在尝试让 QueryDSL 用于 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 ，它不会生成任何源代码。
欢迎任何建议。
编辑： maven-apt-plugin 的唯一输出是这样的：
[INFO] --- maven-apt-plugin:1.0.2:process (default) @ suivitrc ---
