TLDR：必须包含哪些包（以及哪些范围）：

  • 在库中使用 JAXB
  • 在图书馆中使用 XJC
  • 在该库中运行测试
  • 将库作为依赖项包含到另一个库中，而不会出现与 JAXB 相关的运行时错误

细节：

我正在使用带有 JDK 16 和 Gradle 的 JAXB 和 XJC。我创建了一个项目 A （即bayern.steinbrecher:SepaXMLGenerator），其中包含带有以下代码段的 JAXB：

dependencies {
    implementation 'jakarta.xml.bind:jakarta.xml.bind-api:3.0.1'
    implementation 'com.sun.xml.bind:jaxb-xjc:3.0.1'
    runtimeOnly 'com.sun.xml.bind:jaxb-impl:3.0.1'
    runtimeOnly 'org.glassfish.jaxb:jaxb-runtime:3.0.1'
}

这工作正常。我什至可以执行我为项目 A 创建的包含测试。

但是，如果我尝试bayern.steinbrecher:Green2通过声明将项目 A 包含在另一个项目 B（即 ）中，implmentation我会被一条错误消息卡住，告诉我，找不到 JAXB 的运行时依赖项。

我完全糊涂了。我阅读了许多网站，说明了如何正确包含 JAXB、Jakarta、Glassfish 参考实现或其他内容的各种不同的事情，而且这些网站中的许多似乎已经部分过时了，因为 JAXB 最初包含在 JDK 中，现在不再包含它并被重命名不知何故去雅加达。

正确包含 JAXB 的最直接和最简单的方法是包含参考 JAXB 实现并排除任何 ZIP 文件依赖项，因为这些会导致Error occurred during initialization of boot layer [...] Module format not recognized您的库被另一个项目本身包含。

implementation('com.sun.xml.bind:jaxb-ri:3.0.2') {
    exclude group: 'com.sun.xml.bind', module: 'jaxb-release-documentation'
    exclude group: 'com.sun.xml.bind', module: 'jaxb-samples'
}

如果包含的依赖项应该进一步最小化jaxb-xjc并且jaxb-jxc也可以被排除。
