![]() If the JDK version in the About dialog doesn't match or didn't change, see below.Notice the vendor (should be JetBrains s.r.o) and the release number (should correspond to the number after b in the file you've downloaded). Verify via About dialog that the new runtime is used.Restart the IDE to try the new runtime.Click the OK button and wait until the file with JetBrains Runtime is downloaded and configured.Installing old runtime versions may render your IDE unusable or introduce new issues. It makes sense to install the most recent version or the version you were asked to try by JetBrains staff. Select the version to install, the higher the number after b, the more recent is the version.Start the IDE, use Help | Find Action (Ctrl+Shift+A or Cmd+Shift+A on Mac), type " Choose Boot Java Runtime for the IDE", press Enter.All platforms: download and install JetBrains Runtime via Choose Boot Java Runtime for the IDE action Our IDEs will not run on the older Java versions like Java 8 or 11. Please note that all the current IDE versions require at least Java 17 version to run. If you need to change the runtime to a different version, see below. Java HotSpot(TM) 64-Bit Server VM (build 25.All the products on all the supported platforms already have 64-bit JetBrains Runtime 17 bundled and it will be used by default to run the IDE. Java(TM) SE Runtime Environment (build 1.8.0_291-b10) It should output the following: java version "1.8.0_291" ![]() Let the system know where JRE is installed: sudo update-alternatives -install "/usr/bin/java" "java" "/usr/local/java/jre1.8.0_291/bin/java" 1Īfter that’s done, check the installation by running: java -version To save space, delete the tarball by running: sudo rm jre-8u291-linux-圆4.tar.gz ![]() Unpack the tarball: sudo tar zxvf jre-8u291-linux-圆4.tar.gz Go into the install directory: cd /usr/local/java Move the JRE binaries into the directory: sudo mv jre-8u291-linux-圆4.tar.gz /usr/local/java InstallingĬreate a directory to install JRE in with: sudo mkdir /usr/local/java Oracle does not currently offer JRE packages for Java 11 or above from their website so, for this tutorial, we will use the Oracle HotSpot JRE version to be 8u291 (Java 8, update 291). An Oracle account is needed to download the Oracle HotSpot JRE. tar.gz (tarball) by heading over to their website. Installing Oracle HotSpot JRE Downloading the Oracle HotSpot JRE binariesĭownload JRE binaries in. In the next step we’ll install Oracle HotSpot JRE. (Although the output may change in the future as new Java versions are promoted to LTS status, or the current LTS version receives updates.) OpenJDK 64-Bit Server VM (build 11.0.11+9-Ubuntu-0ubuntu2, mixed mode) OpenJDK Runtime Environment (build 11.0.11+9-Ubuntu-0ubuntu2) It should output the following: openjdk version "11.0.11" We can check if OpenJDK JRE was properly installed by running: java -version To install the OpenJDK JRE, we run: sudo apt install default-jre (Alternatively, you may opt to use a specific Java version, using for example the openjdk-11-jre package as updates are released for that version of the Java Virtual Machine, that packages will be updated, allowing you to stick to the latest and greatest update of one specific version of the Java language.) The default-jre is an excellent choice for most situations, thanks to the outstanding track of backwards compatibility of the Java Virtual Machine. Ubuntu offers the default-jre package, which is regularly updated to ship the latest version of the current OpenJDK JRE in Long Term Support (LTS). Moreover, the non LTS versions of Java are bringing a steady stream of innovation into the language, and also see some adoption. ![]() Nowadays, Java 11 is the current Long Term Support (LTS) version, but Java 8 is still widely used. With new versions of Java released every 6 months, there are multiple versions available for use. ![]()
