대략 이런 에러가 발생했을 경우.

POM.xml을 확인해보면 

<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>

    <artifactId>msrdecision</artifactId>
    <packaging>war</packaging>
    <version>1.0-SNAPSHOT</version>
    <name>msrdecision Maven Webapp</name>
    <url>http://maven.apache.org</url>
    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>

            <scope>test</scope>
        </dependency>
    </dependencies>
    <build>
        <finalName>hello</finalName>
    </build>
</project>

이렇게 되어 있을 것이고,
해결방법은 POM.xml에

<dependency>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>2.4.3</version>
</dependency>

이런식으로 디펜던시를 추가해주면 된다.(현재 날짜 기준으로 최신버전인 3.2.1은 되지 
않는다.)

이렇게 작성해준 뒤에, 
1. 프로젝트 우클릭 > Run As > Maven Install
2. 이클립스 프로젝트 탐색기에서 해당 프로젝트 클릭 후 F5(새로고침)
3. 프로젝트 우클릭 > Maven > Update Project
