jaxb2-maven-plugin Jakarta 和 java 11

Ima*_*man 13 java xjc jakarta-ee

我正在尝试迁移到 java 11 和 jakarta。我需要像在 Java EE 中那样从 XSD 文件创建 java 类。我已将所有 jaxb 导入更改为 jakarta。但我无法使 jaxb2 使用 jakarta namspace 而不是 jaxb 创建类。\n如果我没有向插件部分添加任何依赖项，那么该类将使用 javax namspace 创建，我不需要它，并且无论如何都找不到导入Java 错误：package javax.xml.bind.annotation does not exist.\n生成的类是：

\n

如果我添加，jakarta.xml.bind那么 FussnoteType 类根本不会生成，我会收到以下错误：
