XMLInputFactory Error - Using StAX in Java Plugin

Answered

I am attempting to use StAX in a plugin that I am developing. However, when I try to make an instance of XMLInputFactory I get the below error.

XMLInputFactory factory = XMLInputFactory.newInstance();

I have been able to find some information about this online, including someone with a similar question (https://intellij-support.jetbrains.com/hc/en-us/community/posts/206132019-Using-StAX-in-Java-5-plugin?input_string=XMLInputFactory ) but unfortuunately none of it has helped me.

I would like to use javax.xml.stream.XMLInputFactory and not com.ctc.wstx.stax.WstxInputFactory. How do I go about this?

I have been able to pinpoint that it is the plugin java-gradle-plugin that causes the problem (see my build.gradle below). Does it change the classpath?

plugins {
id 'java'
id 'org.jetbrains.intellij' version '0.4.9'
id 'java-gradle-plugin'
}

I have updated the question since figuring out that the plugin java-gradle-plugin causes this error to appear. If I do not include it in my build.gradle, then XMLInputFactory works fine. Why is this and how do I go about fixing it? Thank you.

plugins {
id 'java'
id 'org.jetbrains.intellij' version '0.4.9'
id 'java-gradle-plugin'
}

Thanks Vladimir. I managed to avoid this issue by adding the gradle plugin as a dependency instead.
