UnmappableCharacterException error in pom.xml plugin

I was getting the following error in pom.xml for maven-war-plugin even after updating Maven - java.nio.charset.UnmappableCharacterException

And as a result, some pages were crashed and tomcat showed some thymeleaf related error in the logs.

This might occur more commonly to those working with Windows systems.

Add the following property to properties of pom.xml -

<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

Also, add following configuration to “maven-compiler-plugin”. Make sure to mention correct Java version in target and source configuration.

<configuration>
        <encoding>UTF-8</encoding>
        <source>11</source>
        <target>11</target>
</configuration>

Run Maven update again and restart the server. It should be resolved after these changes.
