If you install just a JRE, and not a full JDK, that error message will persist. Installing that will not solve the problem, because recent versions of Eclipse require a higher version.

If you're using Mac, and you don't have a JDK installed, you may get a bogus message from the OS stating that you should 'install the legacy Java SE 6 runtime'.

If you're using Windows, you may already have a JRE installed, but upgrading usually won't hurt.

If you aren't planning to use Eclipse for Java development and want to save some disk space, install a JRE. If you intend to use Eclipse for Java development, then you should install a JDK.

Regardless of your operating system, you will need to install some Java virtual machine (JVM).

In all cases, Eclipse requires a 64-bit JVMĪ Java Development Kit (JDK) includes many useful extras for Java developers including the source code for the standard Java libraries. If you are using Eclipse to do Java development, or are on macOS, install a JDK. The system will not install a JRE that has an earlier version than the current version.Current releases of Eclipse require Java 11 JRE/JDK or newer. When you install the JRE, you can install only one JRE on your system at a time. To install an earlier version of the JRE, you must first uninstall the current version. To determine the current JRE version installed on your system, see Determining the JRE Version Installed on macOS. However, the system will not replace the current JRE with a lower version.

Installing the JDK and JRE on macOS is performed on a systemwide basis for all users. You cannot install Java for a single user. The following are the system requirements for installing the JDK and the JRE on macOS:
