Add items to your project

Once you have created a project, you can start adding new items: create directories and packages, add new classes, import resources, and extend your project by adding more modules.

Create new items

Packages in Java are used for grouping classes that belong to the same category or provide similar functionality, for structuring and organizing large applications with hundreds of classes.

Create a new empty file

Together with the file, IntelliJ IDEA automatically generates the class declaration.

Create a new module

Modules allow you to combine several technologies and frameworks in one application. In IntelliJ IDEA, you can create several modules in one project and each of them can be responsible for its own framework.

Import items

Images belong to resource files. They should be stored in a dedicated folder – Resources Root. If you don’t have this folder in your project, create a new directory, right-click it in the tool window, and select .

Import an existing module

You can import a module to your project by adding the file from another project:

Post navigation

Content in IntelliJ IDEA is a group of files that contain your source code, build scripts, tests, and documentation. These files are usually organized in a hierarchy. The top-level folder is called a .

Modules normally have one content root. You can add more content roots. For example, this might be useful if pieces of your code are stored in different locations on your computer.

At the same time, modules can exist without content roots. In this case, you can use them as a collection of dependencies for other modules.

The content root directory in IntelliJ IDEA is marked with the

Add a new content root

Configure folder structure

Folders within a content root can be assigned to several categories.

Configure folder categories

This way, you can assign categories to subfolders as well.

You can also configure folder categories in .

Exclude files and folders

If you don’t need specific files, but you don’t want to completely remove them, you can temporarily exclude these files from the project. Excluded files are ignored by code completion, navigation, and inspections.

To exclude a file, you need to mark it as a plain text file. You can always return excluded files to their original state.

Exclude files and folders by name patterns

In some cases, excluding files or folders one by one is not convenient. For example, this may be inconvenient if your source code files and files that are generated automatically (by a compiler, for instance) are placed in the same directories, and you want to exclude the generated files only. In this case, you can configure one or several name patterns for a specific content root.

If a folder or a filename located inside the selected content root matches one of the patterns, it will be marked as excluded. Objects outside the selected content root won’t be affected.

All files within excluded folders will be excluded as well.

Assign a package prefix to Java sources

In Java, you can assign a package prefix to a folder instead of configuring a folder structure manually. A package prefix can be assigned to source folders, generated source folders, test source folders and generated test source folders.

Change the output path for resources

When you’re building a project, the resources are copied into the compilation output folder by default. You can specify a different directory within the output folder to place resources.

Root ideas

In recent years the availability of computers and automated data collection and analysis in great detail has enabled vast strides to be made in all branches of science,  so much so that mathematical modelling is now the norm in all areas.  The efficiency of these processes has allowed many alternative models to be studied.  In some cases this profligacy of models can cause a problem and I feel that some thinking on the philosophy of science is needed to help us select the routes that we should take for the next assault on understanding everything that exists even those bits that we will never be able to see and measure.

Snags and pitfalls

The paragraph above hints at some fundamental problems in modern science.  some six years after I first wrote this I feel that I have now worked through some important and very human problems we have with out current thinking.  these are:

I plan to develop these concepts into pages for the future.

IntelliJ IDEA works with multiple Java testing frameworks out of the box, for example, JUnit, Spock, TestNG, or Cucumber.

In the IDE, you can create a test class directly from the source code together with the necessary test methods. You can switch between test classes and source code with a shortcut, run multiple tests, view statistics for each test, and export test results to a file.

IntelliJ IDEA also features code coverage that allows you to analyze your code and understand which areas of your code are covered by tests and which areas require more testing.

For information on how to test your code in other languages, refer to:

Add testing libraries

IntelliJ IDEA allows you to add missing libraries as you code: once the IDE detects that you’re using some code from the library that is not added to your project yet, it will prompt you to download and install it.

You can also add libraries to your project manually. For example, this can be helpful if you need a specific library version or distribution.

Manually add a testing library

IntelliJ IDEA allows you to add missing libraries as you code: once the IDE detects that you’re using some code from the library that is not added to your project yet, it will prompt you to download it. In this case, the IDE automatically adds the necessary dependencies to your .

Add libraries using the Dependencies tool window

In Gradle projects, add the necessary dependencies to your build file manually.

Test Sources Root

Before you start creating tests, make sure that the Test Sources Root is configured for your project. The Test Sources Root is a folder that stores your test code. In the tool window, this folder is marked with the

The IDE processes the code from different sources differently. For example, compilation results for sources and test sources are normally placed into different folders. That is why, if the test sources root is missing, you need to create one. Otherwise, your code might be processed incorrectly.

Create a test root for your project

Maven uses a standard directory layout for applications. Generally, it’s recommended that you conform to this layout in your projects. For example, when you create a test folder in IntelliJ IDEA for a Maven project, the IDE suggests setting the standard name and location for such a folder. In this case, the IDE is also already aware that this test folder is your Test Sources Root.

However, you can override the standard directory layout by modifying the build file.

Change the test root

The new test root should be marked with the

Just like Maven, Gradle also has a strict project directory layout. When you create a test folder in IntelliJ IDEA for a Gradle project, the IDE suggests setting the standard name and location for such a folder. In this case, the IDE is also already aware that this test folder is your Test Sources Root.

Use another test root

Test Resources Root is a folder that stores files associated with your test sources. In the tool window, this folder is located in the test root and is marked with

For Maven and Gradle projects, the test resources folder is usually created automatically. If you’re building your project with the native IntelliJ IDEA builder, you might need to create the resource root manually.
