Downloading and Installing the JRE


Before you begin downloading and installing Eclipse, you have to make sure you have the Java Runtime Environment (JRE) downloaded and installed on your machine. Because Eclipse as an application was written in Java, it requires the JRE to run. If the JRE is not installed or is not detected, you will see the following error if you try to open the Eclipse environment:

  • If you are downloading to a Microsoft Windows environment, when you see the notification in the following illustration, click Run to begin the installation of the JDK.
  • During the installation process, you will be prompted to read and accept the License Agreement, shown next. After agreeing to the standard License Agreement and clicking.Next, you will be able to select your custom setup options
  • To keep the process simple, and fairly standardized, you should accept the suggested packages by default everything is selected—and continue the installation by clicking Next. When the Installation Completed page appears, shown in the following illustration, click Finish and your installation should be completed
  • Once you complete the Java JDK installation—and by default the JRE installation—you can begin to install Eclipse.
