error: cvc-elt.1.a: Cannot find the declaration of element 'project'
I am getting this error constantly. Whenever I create a project using maven it starts displaying this error. I have even mentioned the 'maven-war-plugin' under plugin tag and then updated and refreshed the project as well.

I have Found the Solution to this problem, Thanks to @M.Deinum who commented the solution below the question.
All I did was add https to the link in the tag, instead of http.
here is the previous code:
<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/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.myfirstmvcapp</groupId>
<artifactId>helloworldabc</artifactId>
<packaging>war</packaging>
<version>0.0.1-SNAPSHOT</version>
<name>helloworldabc Maven Webapp</name>
<url>http://maven.apache.org</url>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.3.1</version>
</plugin>
</plugins>
<finalName>helloworldabc</finalName>
</build>
</project>
Here is the lastest code, all that is needed is to add https instead of http to the xsd link in the last link of project tag.
