avro-maven-plugin 生成未使用的导入

问：

我正在将Apache Kafka与AVRO一起使用。 我们通过编写 AVDL 文件并使用 avro-maven-plugin 和编译器等来生成/编译它们来创建 Java 类。

生成后，从 AVDL 文件生成的所有 Java 类，其记录类型包含未使用的导入，例如：

import org.apache.avro.generic.GenericArray;
import org.apache.avro.util.Utf8;

Utf8 导入确实有时会使用，但经常被生成而不使用。 GenericArray我从未在任何地方找到过。

如果不使用这些导入，是否有可能阻止生成这些导入？生成已经包含警告的代码不太好。

我的 pom.xml 如下所示：

我试图在互联网上找到一些有关此的信息，但没有找到任何东西。 在没有警告的情况下生成 Java 代码会很好。

谢谢！
