SpringBoot: can't create ear with maven: Unable to deduce layout - spring

Question

I have a SpringBoot project with the war and ear module, that I build using maven ( a build automation tool used primarily for Java projects.) and IntelliJ IDEA This is my pom.xml of the war project:
<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

But when I build the class I have this error:

Try removing the following from your top pom...
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
