So recently I added a pom.xml file to my java project in IntelliJ Idea and I then made it into a maven project. Though when I opened the pom.xml back again with IntelliJ I saw 2 errors at “project” from the first project tag (<project). This Error weirdly only appeared after I changed a letter that wasn’t important and then never went away unless I went on a different window. Can somebody tell me why this is happening and how I can fix it?

Here is my pom.xml by the way:

<?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">

    <modelVersion>4.0.0</modelVersion>

    <groupId>com.eplusplus</groupId>
    <artifactId>e++</artifactId>
    <version>1.0.0</version>

    <name>E++</name>
    <description>A brief description of my project</description>
    <url>http://www.example.com/my-project</url>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.8.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

I expected there to be no error since even AI doesn’t what the f**k is wrong with my code.
