I am trying to use the Woodstox StAX parser in a plugin for Android Studio that I am building in IntelliJ using gradle.

I get the below error when trying to get an instance of an XMLInputFactory2.

XMLInputFactory2 xif = (XMLInputFactory2) XMLInputFactory.newInstance();

java.lang.ClassCastException: com.sun.xml.internal.stream.XMLInputFactoryImpl cannot be cast to org.codehaus.stax2.XMLInputFactory2

I have already come across posts with similar issues, but nothing has helped me overcome this problem.

I am aware that this has something to do with how I import the Woodstox dependency. Below is part of my build.gradle, with two attempts of importing woodstox (don't know if fasterxml or codehouse is correct) and mutliple attempts at trying to exclude the classes that could be causing the problem.

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.12'
    implementation "org.gradle:gradle-tooling-api:5.4.1"
    runtimeOnly 'org.slf4j:slf4j-simple:1.7.10'
    // https://mvnrepository.com/artifact/com.fasterxml.woodstox/woodstox-core
//    compile (group: 'com.fasterxml.woodstox', name: 'woodstox-core', version: '5.2.1') {
//        exclude group: 'stax', module: 'stax-api'
//        exclude group: 'com.sun.xml', module:'internal'
//    }

    // https://mvnrepository.com/artifact/org.codehaus.woodstox/stax2-api
    compile ('org.codehaus.woodstox:stax2-api:4.2') {
        exclude group: 'com.sun.xml', module:'internal'
        exclude group: 'javax.xml.stream', module:'stax-api'
        exclude group: 'stax', module:'stax-api'
    }
}

How can I fix this error? What is the correct way to add Woodstox as a dependency in gradle? Thank you very much.

Did you try this https://intellij-support.jetbrains.com/hc/en-us/community/posts/360004198559-XMLInputFactory-Error-Using-StAX-in-Java-Plugin?page=1#community_comment_360000581560

Thanks Yann. No, I managed to avoid that issue by adding the gradle plugin as a dependency instead.

I think I may have a solution to this error by using the woodstox osgi InputFactoryProviderImpl, but I am just trying to fix other errors that arise with it.

import com.ctc.wstx.osgi.InputFactoryProviderImpl;
import com.ctc.wstx.osgi.OutputFactoryProviderImpl;
import org.codehaus.stax2.XMLEventReader2;
import org.codehaus.stax2.XMLInputFactory2;
import org.codehaus.stax2.XMLOutputFactory2;

InputFactoryProviderImpl iprovider = new InputFactoryProviderImpl();
OutputFactoryProviderImpl oprovider = new OutputFactoryProviderImpl();

XMLInputFactory2 ifactory = iprovider.createInputFactory();
XMLOutputFactory2 ofactory = oprovider.createOutputFactory();

XMLEventReader2 in = (XMLEventReader2) ifactory.createXMLEventReader(
        new BufferedInputStream(
                new FileInputStream(filePath)));
XMLEventWriter out = ofactory.createXMLEventWriter(result);
