无法从Eclipse中的动态Web项目的Maven依赖项导入类

Question

I converted a dynamic web project into a maven project by right-clicking on the project and choosing Configure -> Convert to Maven Project. I added below dependency jar in pom.xml.

<dependency>
            <groupId>io.rest-assured</groupId>
            <artifactId>rest-assured</artifactId>
            <version>3.1.0</version>
            <scope>test</scope>
        </dependency>

Then, right clicked project -> Run as -> maven install. The installation was successful.

Now all the jars and classes are available under the Maven Dependencies section. Below is screenshot of my project structure.

However, I am unable to import any package or class form the dependency jars into any of my Java class (Ex: HttpServices.java) in src folder. I am unable to use the jars although they are downloaded.

I tried updating Maven project (Force clearing snapshots), clean project, build project but nothing worked. I have no errors in the project. Also, when I added the jars directly into the build path (using add external jars ie without maven) it worked perfectly fine. Please help in resolving the problem.

Note: Other Java-maven projects are working fine. Problem is only with this converted maven project. I am using Eclipse Java EE IDE for Web Developers. Version: Photon Release (4.8.0) and jdk 8

Below is the generated pom.xml. Compiler and war plugins were automatically generated when I converted the project to maven. I only added the dependency.

        </configuration>
      </plugin>
    </plugins>
  </build>
  <dependencies>
        <dependency>
            <groupId>io.rest-assured</groupId>
            <artifactId>rest-assured</artifactId>
            <version>3.1.0</version>
            <scope>test</scope>
        </dependency>
    </dependencies>
</project>

Below is the class path entry for maven.

<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
        <attributes>
            <attribute name="maven.pomderived" value="true"/>
            <attribute name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>
        </attributes>
    </classpathentry>

Because of <scope>test</scope> everything of this dependency is available only in test source , not in the main source.

Remove <scope>test</scope> , right-click the project and choose Maven > Update Project... .
