NoClassDefFoundError：由于缺少依赖关系，无法加载类groovy.xml.jaxb.JaxbGroovyMethods javax / xml / bind / Unmarshall

Posted 2021-03-30

我们的Gradle版本在--add-modules=java.xml.bind,java.activation,java.xml.ws.annotation有options.compilerArgs到JavaCompile，用JDK9 / 10构建。这现在很好用，但这些模块已被弃用。

我想准备JDK11，其中these modules might be removed。

我曾尝试将javax.xml.bind:jaxb-api:2.3.0，com.sun.xml.bind:jaxb-impl:2.3.0和com.sun.xml.bind:jaxb-core:2.3.0添加到compile和runtime以及classpath中的buildscript，但我仍然得到NoClassDefFoundError。

我错过了什么？

报告的缺失类别对于每个构建都不是100％相同：它在抱怨javax/xml/bind/JAXBContext，javax/xml/bind/Unmarshaller和javax/xml/bind/Marshaller之间切换。

答案

build.gradle依赖项中的这一行解决了这个问题：

    compile group: 'javax.xml.bind', name: 'jaxb-api', version: '2.3.0'

另一答案

好吧，这解决了自己，可能是由于新的Groovy（2.5.1）和Gradle（4.7）依赖。
