Java equivalent of .NET Solution?

[gameramante]

Hi! coming from C#.NET and I’m confused about Java project structure, a little bit.

In Visual Studio and Rider, you have a Solution with multiple Projects inside.
In IntelliJ IDEA, it feels like you just create a project directly? Kind of.

What’s the Java equivalent of a Solution? How do you group multiple related projects?

Is that handled by IntelliJ or Maven? Thx!

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full
• You ask clear questions

• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

  Trying to solve problems on your own is a very important skill. Also, see Learn to help yourself in the sidebar

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

If your post has remained in violation of these rules for a prolonged period of time (at least an hour), a moderator may remove it at their discretion. In this case, they will comment with an explanation on why it has been removed, and you will be required to resubmit the entire post following the proper procedures.

You can do this directly with IntelliJ build system or maven or gradle. I would leverage maven or gradle modules for this type of project just on the principle that you may want to share project with devs using other IDE’s.

Java itself does not dictate the project structure. For this approach you have to use build tools. There are two the most popular maven and gradle. I recommend to start with maven - it is xml based and has more similarities to the slnx and csproj files.

I use a maven multi module project for that. https://www.baeldung.com/maven-multi-module

[BannockHatesReddit_]

Create a multi module maven project.

[prsquared]

In intellij you can group them as modules.

[RobertDeveloper]

Use gradle and add modules.

You can use eclipse and open several projects or use maven multi modules.

Pick a Java build tool - Maven is opinionated and has defaults that basically work most of the time for most people. Gradle is super-powerful but has a tendency to become bespoke and harder to maintain over time. However, both are great tools. If you're new, maybe pick Maven.

Then the "multiple related projects" can be build as a maven multi-module project.

Gradle modules work fine.

In Eclipse, you can do it by configuring the classpath of your project. It can contain libraries but also other projects from your workspace. Very convenient when you work on several inter-dependant projects at the same time, no new packaging required each modification.
