How to simply download a JAR using Maven?

Question

How do I download JAR during a build in Maven script?

Answer 1

Normally you don't use Maven for "just downloading", but for your build process. So normally, you do the following steps:

1. Define a new project by defining the archetype of your project and some needed properties.
2. Define as a dependency the library you want to use.
3. Run Maven with mvn compile

As a side effect, you will have downloaded the library to your local Maven repository. There are a lot of plugins to do something with dependencies, so have e.g. a look at the Maven Dependency plugin.
