“When building our Spring Application, we need to manage our dependencies.”
“We need to import the ‘Jar’s that is required for Spring Applications to work.”
Maven: Build Independency Management Tool
Lets you declare all the dependencies you want in a single file.
- No more needing to download the JARs and adding it into the CLASSPATH.
- Rather, you mention what JARs you need into the file pom.xml.
- pom.xml contains a list of all your dependencies that Maven needs to know/to get
- After running a Maven cmd, Maven will check what dependencies are needed for the app, and will get the JARs from a Repository.
In short:
1. When needing dependencies, we create the pom.xml file.
1. Add a list of dependencies onto the pom.xml file.
1. Then run a Maven cmd.
Maven also lets you create a starter project. (no need to create this individual files yourself)
- Comes with an ‘Archtype’ (basically a template) which lets you start a simple project.
- In other words, Maven basically creates files, including the pom.xml file for you to begin listing dependencies you need.
