Importing a Maven project as a sub project in an existing project in eclipse

I am trying to import a maven project into eclipse as a subproject of a non-maven project.
The structure am seeking should look like the image below
I have tried to import the parent project and then create spring starter project and select the path to be inside the parent but I ended up with an independent project in the workspace that is duplicated in parent.
Thank in advance.

I don't think you can do that. What you can do is a modular maven project. Declare your spring-cloud as parent and guest-services as a module:
spring-cloud pom like:
<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>x.y.z</modelVersion>
<groupId>org.yourCompany.spring-cloud</groupId>
<artifactId>spring-cloud-parent</artifactId>
<version>1.0-SNAPSHOT</version>
<properties/>...
<dependencies/>...
<build/>...
<modules>
<module>guest-services</module>
</modules>
</project>
guest-services pom like:
<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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>x.y.z</modelVersion>
<groupId>org.yourCompany.guest</groupId>
<artifactId>guest-services</artifactId>
<name>guest-services</name>
<description>Description for this module</description>
<parent>
<groupId>org.yourCompany.spring-cloud</groupId>
<artifactId>spring-cloud-parent</artifactId>
<version>1.0-SNAPSHOT</version>
<relativePath>..</relativePath>
</parent>
<properties/>...
<dependencies/>...
<build/>...
</project>

Maven child module not found when building

I am trying to learn how maven multi-project builds work. I have a very simple setup right now, a top level POM that defines 1 subproject, the web application, and a web project that has a pretty basic pom file. From the parent level directory, when i try to run 'mvn clean install' i get the following error:
Child module /home/jeb/Desktop/payroll/payroll-web> of /home/jeb/Desktop/payroll/pom.xml does not exist
Here is the parent pom:
<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>payroll</groupId>
<artifactId>payroll-top</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>
<modules>
<module>payroll-web></module>
</modules>
</project>
And here is the subproject (web app) pom.xml
<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>
<name>payroll-web</name>
<parent>
<groupId>payroll</groupId>
<artifactId>payroll-top</artifactId>
<version>0.0.1-SNAPSHOT</version>
<relativePath>../pom.xml</relativePath>
</parent>
<groupId>payroll</groupId>
<artifactId>payroll-web</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>war</packaging>
<dependencies>
</dependencies>
<build>
<finalName>payrollwebapp</finalName>
</build>
</project>
I'm not sure what I am missing to get the project to build, any help is appreciated.

You have a trailing ">" at the end of the module name.
<module>payroll-web></module>

`<parent>
<groupId>payroll</groupId>
<artifactId>payroll-top</artifactId>
<version>*0.0.1-SNAPSHOT*</version>
<relativePath>../pom.xml</relativePath>
</parent>`
Correct the parent version to 1.0

under target folder under classes i still have
I'm basically trying to have a rest service in WARModule but unable to make it work, any help is appreciated. Thanks!!

You need to follow the Maven standard folder structure.
You should put all your java code inside src/main/java folder.
Looking at the image you uploaded, it looks like the SampleApp.java is not present in the correct directory as expected by maven.

Error in pom.xml with dependencies: Missing artifact org.eclipse.jetty.tests:test-mock-resources:jar:9.1.0.v20131115

My pom.xml file:
<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">

<groupId>org.eclipse.jetty</groupId>
<artifactId>example-jetty-embedded</artifactId>
<version>9.1.0.v20131115</version>
</dependency>
</dependencies>
</project>
and I got a problem:
Missing artifact
org.eclipse.jetty.tests:test-mock-resources:jar:9.1.0.v20131115
I see that mvnrepository does not contain this jar file (http://mvnrepository.com/artifact/org.eclipse.jetty.tests/test-mock-resources)
How can I fix this problem?

Test resources are not deployed to maven central by the Jetty project.
And example projects are usually not considered dependencies.
