Tomcat Error: An internal error occurred during: "Updating status for Tomcat v6.0 Server at localhost ...". Java.lang.NullPointerException

A dependency was added to the pom file in the MAVEN project and an error occurred when publishing the results to Tomcat:

<!--Struts2-spring-plugin It relies on Spring 4.1.6, and I'm using a spring version of 5.0.2--
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-spring-plugin</artifactId>
<version>2.5.12</version>
</dependency>

1. The error is similar to the following connection:

3. Solution

Instead of using the scheme given in the above 2, I swapped my spring version to 4.1.6, so that you can publish to Tomcat without an error.
