NoClassDefFoundError:由于缺少依赖项javax/xml/bind/Unmarshaller，无法加载groovy.xml.jaxb.JaxbGroovyMethods类

我们的Gradle构建有

——在
JavaCompile
中添加modules=java.xml.bind、java.activation、java.xml.ws.annotation

到

options.compilerArgs

以使用JDK9/10构建。现在这很好用，但是这些模块已经被弃用了

我想为JDK11做准备

我已经尝试将

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

编译
和
运行时
以及
buildscript
中的
类路径
，但我仍然得到
nocsdeffounderror

我错过了什么

报告的缺失类对于每个构建不是100%相同：它在抱怨
javax/xml/bind/JAXBContext
、
javax/xml/bind/Unmarshaller
和
javax/xml/bind/Marshaller
构建中的这一行之间切换。gradle
依赖关系解决了我的这个确切问题：

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

好的，这就解决了，可能是由于新的Groovy（2.5.1）和Gradle（4.7）依赖项。
我无法告诉您如何正确解决问题，但我可以提出一个解决方法：将您的
JDK_JAVAC_OPTIONS
环境变量设置为
--addmodules java.xml.bind
@ZhekaKozlov
--add modules java.xml.bind
JDK/11不需要，对吗？还有，你查过了吗？很高兴看到您使用的
build.gradle
依赖项。@neu242我对gradle几乎一无所知，所以这些都是猜测。。。我最多可以想到三个可能需要这些依赖关系的活动部分：（a）Gradle进程本身，（b）为编译启动的进程，（c）正在编译的源代码。我猜（b）是这样的-你确定你已经把这些罐子加到（b）了吗？我会使用完整的调试输出运行Gradle，并希望找出这些JAR的确切显示位置。@neu242您使用完整的调试输出运行了吗？如果您使用Maven实现了这一点，它将向您显示用于每个进程的确切类路径。这至少可以回答这个问题，JAR是否最终位于正确的位置。对于那些有足够分数并且喜欢使用groovy的人，请投票支持重新开始这个问题。这是一个非常特殊的错误，在2.5.1/2.5.2中修复了它。但对我来说不是：（我想知道我的设置有什么问题……groovy版本是什么？2.5.2？在撰写本文时，我使用的是groovy 2.5.0和Gradle 4.7。当问题解决时，我使用的是groovy 2.5.1和Gradle 4.10。这是正确的。创建2.5.1是为了解决您提到的问题。
