How to create spring boot project from existing maven project

Question

I have created a maven project in eclipse and I want to deploy it on a server(tomcat I guess). I believe this can be done via spring boot. My question is this: this project has imported several jar files located on my PC and has another project that is in the workspace in its build path. I worry that during the integration(turning it into maven) I might lose all the dependencies. What is generally the best way to import jar files to a project and how to add another project in its build path? Please comment with any other specifications that you need.

This is the pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" 
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

For integrating local jar files in your maven project, have a look to: How to add local jar files to a Maven project?

To add Spring Boot to your pom.xml, you need to add the following (from this doc

<!-- Inherit defaults from Spring Boot -->
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.5.RELEASE</version>
</parent>

<!-- Add typical dependencies for a web application -->
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

<!-- Package as an executable jar -->
<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>
