如何解决“Exception in thread 'main' java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter”问题

Question

我看到一些关于它的帖子，但并没有真正帮助我...

我有java JDK 10，运行在Windows 10 64位系统上。我正在尝试使用一个机器人。关于它的github链接在这里。

这是我正在执行的脚本的日志

看起来 javax/xml/bind/DatatypeConverter 的实现不在你的类路径上。 - Scary Wombat

它对我有效。 - Ballo Ibrahima

Answer 1

在JDK 9中，java.xml.bind已被弃用并从标准类路径中移除。它仍然存在，因此您可以尝试使用--add-modules来将模块添加到类路径中。

但对于我来说，最简单的解决方案是添加依赖项（gradle/maven）：

gradle：

compile 'javax.xml.bind:jaxb-api:2.3.0'

maven:

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>

链接到废弃摘要：https://docs.oracle.com/javase/9/docs/api/java.xml.bind-summary.html

Answer 2

我发现为什么它不起作用了。我需要降级到Java JDE和JDK 8版本。

虽然这是一个可能的解决方案，但它将绑定您到该Java版本。我强烈建议遵循@sagat的方法。 - jrsall92
