Eclipse is one of Java’s most famous development environments: it contains everything you need to build Java projects from scratch. To be able to start working on a new project, you must first create it. Although it is quite simple, but if you have installed Eclipse for another programming language, creating a new Java project in Eclipse can be confusing for you.

Install Eclipse IDE for Java Developers. When you first install Eclipse, you will be given an IDE (integrated development environment). Select “Eclipse IDE for Java Developers” (Eclipse Integrated Development Environment for Java Developers). The necessary files and tools for Java project initialization will be installed.
- If Eclipse is already installed for another programming language, you can add Java support from Eclipse itself. Click the “Help” menu and select “Install New Software”. Select “All Available Sites” from the top in the drop-down menu and then type “java” in the Filter field. Check the “Eclipse Java Development Tops” box and click “Next”. Follow the instructions to download and install the Java tool. After the tool is installed, Eclipse will restart.

Click “File” → “New” → “Java Project”. The “New Java Project” window will open. [1] X Research Source
- If the “Java Project” option does not appear but Java Development Tops is installed, select “Project…” from the “New” menu. Expand the “Java” folder and select “Java Project”.

Give the project a name so that you and other users can identify it. You can still rename the project later if you need/want.

Select the location to save the project file. By default, they are saved to the Eclipse folder. You can customize this save location if you want.

Select the Java runtime environment (JRE) you want to use. If you are creating a program for a particular JRE, select that environment from the drop-down menu. By default, the latest JRE will be selected.

Choose your project layout. You can choose to use the project folder or create separate folders for the source and class files. Eclipse’s default layout option is “Create separate fpders…”. However, you may have to change depending on the requirements of the project. [2] X Research Source

Click “Next” to open the “Java Settings” window. This is where you specify additional sources and add libraries to the project.

Use the Source tag to specify the build path. The compiler will rely on that to build the program. You can create sub-source directories, link to external sources, or add and remove directories from this build. The compiler uses the build method to determine the source to compile.

Use the Libraries tab to add libraries to your project. This tab allows you to add JAR files to your project as well as choose which pre-built libraries to use. Thanks to the JAR file import function, you can use libraries from other projects.

Click “Finish” to start working on the new project. You will be redirected to your Java workspace. If before starting this project you were working with another programming language then you will be asked to switch to the Java “perspective” in order to get the most out of the program’s IDE.
- Your project will be displayed in the “Package Explorer” pane on the left side of the window. If only Eclipse’s Welcome tab is available, click the little Java button on the left side of the window. [3] X Research Sources

- If you want to change the settings after creating the project, right click on the project name and navigate to the desired option.
