Spring boot and Maven / Whis is Maven?

| What is Maven?

• Maven is a Project Management tool
• Most popular use of Maven is for build management and dependencies

 

| What Problems Does Maven Solve?

• When building your Java project, you may need additional Jar files
• For example: Spring, Hibernate, Commons Logging, JSON etc.,
• One approach is to download the JAR files each project web site.
• Manually add the JAR files to your build path / classpath

 

| Maven Solution

• Tell Maven the projects you are working with (dependencies)
• Maven will go out and download the JAR files for those projects for you
• And Maven will make those JAR files available during compile/run
• Think of Maven as your freindly helper / personal shopper :-)

 

| Maven - How It Works

 

 

| Handling JAR Dependencies

• When Maven retrieves a project depencency
• It will also download supporting dependencies
• For example : Spring depends on commons-logging...
• Maven will handle this automatically

| Building and Running

• When you build and run your app, Maven will handles class / build path for you
• Based on config file, Maven will add JAR files accordingly
