Maven dependency - Maven Install / update project

Question

Maven Install downloads the dependencies from POM or update Project option does it ?

Answer 1

In Eclipse, Maven install runs the following command on your project: mvn install

Which automatically updates any dependencies, then builds all modules and installs them in the local repository.

However, choosing "build project" in Eclipse automatically invokes Maven.

Maven Update - This will bring the jars downloaded in the repository into the eclipse Maven Install - This will perform the Maven life cycle till install (Validate -> Compile -> test-> package ->verify -> Install)
