我正在尝试使用 maven 执行 acceleo 项目。这是 pom 配置：

pom.xml

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.2.1</version>
    <configuration>
        <mainClass>src.AcceleoProject.files.Generate</mainClass>
        <arguments>
            <argument>/${project.basedir}/src/main/java/src/AcceleoProject/files/model.uml</argument>
            <argument>/${project.basedir}/src/main/java/src/AcceleoProject/files/out</argument>
        </arguments>

    </configuration>
</plugin>

错误

当我执行 pom 时，出现以下错误：

我认为它与我要生成文件的输出文件有关。有人对此有任何想法吗？先感谢您。
