element linkXRef is not allowed intelij maven

Question

I'm using IntelliJ version 2021.3.1. In in of my pom.xml I'm getting error message Element linkXRef is not allowed here.

Here is my pom.xml looks like:

    <plugin>
  <artifactId>maven-pmd-plugin</artifactId>
    <configuration>
      <targetJdk>1.8</targetJdk>
       <rulesets>
            <ruleset>../favorites.xml</ruleset>
          </rulesets>
          <linkXref>true</linkXref>
          <format>xml</format>
          <aggregate>true</aggregate>
          <verbose>true</verbose>
          <includeTests>false</includeTests>
          <excludes>
            <exclude>**/generated/*.java</exclude>
          </excludes>
        </configuration>
      </plugin>

Is there a work around for this on Intellij? It is legacy code and I do not want to remove it.

Answer 1

The parameter should be written with a capital R and a capital X. You mistakenly typed a lowercase R. Although this may be legacy code, when experiencing errors on a particular parameter it is a good idea to delete it and use the IDE to autocomplete/select the parameter name.

Solution: linkXRef instead of linkXref
