Don't use <pluginManagement> in pom.xml and thentry. This plugin locks versions due to which it does not accept any version available on your system/environment.Your build tag will be like this:

Try with this:

<build>
    <finalName>WebProjectWithMavenSpring</finalName>
      <plugins>

        <plugin>
          <artifactId>maven-war-plugin</artifactId>
          <version>3.0.0</version>
        </plugin>
