For Generating Jar File-
You can extend your project by maven-assembly-plugin.What is Assembly Plugin-
An "assembly" is a group of files, directories, and dependencies that are assembled into an archive format and distributed. For example, assume that a Maven project defines a single JAR artifact that contains both a simple application and a web application. Such a project could define two "assemblies" that bundle the application with a different set of supporting scripts and dependency sets. One assembly would be the assembly for the simple application, and the other assembly could be a web application bundled with a slightly different set of dependencies. for more about assembly plugin click here<plugin>

Include these line in your pom.xml and make build of it by using maven command -
mvn package
After the build you will get 3 jars. The main one will be the same as a usual Maven project, while the second one will have the classifier appended with exec and be the executable JAR. The third jar name will be appended by jar-with-dependencies and will contain your classes with classes added as dependencies in your spring boot application(spring-boot-starter-web, thymeleaf,...), so into the pom of the application where you want to add that project as dependencies you won't have to add dependencies from spring boot project.
