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. You may either install a Java Runtime Environment (JRE), or a Java Development Kit (JDK), depending on what you want to do with Eclipse. 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.

Once you've downloaded the Java RPM, upload it to your server and navigate to the directory it was uploaded, then run ' rpm -Uvh jdk*.Current releases of Eclipse require Java 17 JRE/JDK or newer. Then you will need to create or login to an Oracle account (free) to download. Go to the following Oracle website to download the latest Java JDK:Ĭlick accept beside the version you want, make sure it is the '.rpm' extension file.

UPDATE April 2022: If you are using a more recent OS version you cam install many OpenJDK versions via dnf/yum, such as Java 17, by running dnf install java-17-openjdk -y or can get direct rpm links to some rpm packages from the website, just use their search feature. We would host it to make your life easier, but it's not worth being sued by a mega-corporation. You will need to make an account on their site, login, download the RPM, upload it to your server and then run the rpm install command. UPDATE April 2019: Oracle now requires you to create an Oracle account to download packages.
