尝试通过Java库进行连接时，Jenkins连接失败

Question

我正在开发一个Jenkins插件，该插件将能够使用java库和WinRm连接到远程Windows机器。我使用的是JDK11.0.8，这是指向库的链接https://github.com/cloudsoft/winrm4j，每当我尝试连接时，我都会出现以下错误：

Provider com.sun.xml.internal.ws.spi.ProviderImpl not found.

我认为Jenkins更喜欢使用内置的解析器，而不是使用pom.xml中提供的解析器。我已经尝试过检查这个问题，对于一些人来说，它已经通过将rt、woodstox或jaxws-rt等库导入pom文件来解决，但在我的情况下，这个解决方案并不成功。此外，我曾尝试在eclipse中手动导入这个包com.sun.xml.internal.ws，但没有成功。

我该如何解决这个问题？

这是完整的错误堆栈

Answer 1

根据您的堆栈，Java类加载器正在委派给：

org.jenkinsci.maven.plugins.hpi.JettyAndServletApiOnlyClassLoader.findClass()

它没有机会加载以"0"开头的类；com.sun.xml."：

protected Class<?> findClass(String name) throws ClassNotFoundException {
if (name.startsWith("javax.")
|| name.startsWith("org.eclipse.jetty."))
return jettyClassLoader.loadClass(name);
else
throw new ClassNotFoundException(name);
}
