[Java] Creating a Maven Project in IntelliJ IDEA

Thu, 28 Apr 2016 07:04:11 +0000

IntelliJ IDEA Version: 15.0

I had been using Eclipse/MyEclipse for Java and Android development, and heard that IntelliJ IDEA is also an excellent IDE. It is a product from the company behind PHPStorm.

What is Maven?

I only recently started using it. I hadn’t written much Java before – I did some JSP during my undergraduate years and wrote some Android code recently. But Java has a rather serious issue with library dependency management, and there are so many library versions. I remember frequently downloading libraries from various places online, then using build path to add external libraries. This approach leads to messy library management, poor version control, and makes it difficult to share code. Maven is a project management tool that handles library versions and dependencies very well.

Creating a Maven Project

File -> New -> Project, select Maven.

If you need to specify the project type such as app or webapp, check “Create from archetype” and select the corresponding type.
Enter GroupId and ArtifactId.

My understanding is that GroupId is the name of the overall parent project or organization the project belongs to, and ArtifactId is the name and purpose of the current project.
Enter the project folder name and path
After creating the Maven project, click “Enable Auto-Import” on the main screen. Otherwise, Maven-managed libraries won’t be automatically imported into the project and will need to be imported manually, which is inconvenient.
View -> Tool Window -> Maven Projects will open a tool window. The main functions you’ll use are clean and compile.
You can use the built-in Maven or your own downloaded Maven. If you want to use your own, go to File -> Settings.

Click clean and compile, and the libraries will be downloaded to your local Maven repository and automatically imported into the current project.
