适用于Node.js开发人员的Java依赖管理

Question

I have been writing code in node.js now for sometime, and node has this nice package manager called npm To install a package, I simple do npm install pkg-name and there it is, in my node_modules folder. There is a package.json file with all my dependencies listed.

I need to write some Java code and Maven seems to be a popular dependency management tool for Java. Although, I had a bit of a tough time wrapping my head around it.

I want to know what are the analogous things in Maven to npm .

So, what's the equivalent to npm install pkg-name in Maven? Where do I find the dependencies? npm has a nice web ui, something like that for Maven?

Any hello world projects for Maven that I can see?

Answer 1

In my opinion, maven does more that npm, by that it can manage not only dependencies, but also the entire build and deployment process. it also integertad with most IDE's like idea or eclipse to make life much easier. I suggest you'll start with some maven tutorial, like this one , it will give you a good grasp of how to start

regarding hello world project - one feature you have in maven is to create a project from an archetype - you can try that out, will give you a good way to look how maven configuration looks like

Answer 2

In maven you don't install packages, but you write all your dependencies in pom.xml. And those are downloaded and used during the build (when you do eg mvn clean install )

pom.xml is a description of your project (eg it contains what dependencies are used, which compiler version, what is the project name, resulting binaries, etc.), there is a description of POM with examples here: https://maven.apache.org/guides/introduction/introduction-to-the-pom.html
