I want to use com.fasterxml.jackson.dataformat.xml.XmlMapper to write or read json class from xml file, but met below issues;
Cannot load class javax.xml.namespace.NamespaceContext (
error: loader constraint violation: loader com.intellij.ide.plugins.cl.PluginClassLoader @4becad6f wants to load interface javax.xml.namespace.NamespaceContext. A different interface with the same name was previously loaded by 'bootstrap'. (javax.xml.namespace.NamespaceContext is in module java.xml of loader 'bootstrap'),
classLoader=PluginClassLoader(plugin=PluginDescriptor(name=XXX XXX XXX for Android, id=com.xxx.xxx.assistant.android, descriptorPath=plugin.xml, path=~/git/assistant-android-gpt-poc/idea-sandbox/plugins/AndroidWizard, version=xxxx package=null, isBundled=false), packagePrefix=null, state=active)

Hi,
It seems that javax.xml.namespace.NamespaceContext is already loaded by a bootstrap classloader and your dependency loads it again. I suggest checking what classes your dependency adds to the plugin. If it has a transitive dependency providing this class, try to exclude it with Gradle dependency management: https://docs.gradle.org/current/userguide/dependency_downgrade_and_exclude.html#sec:excluding-transitive-deps
