In the next dialog, specify the JDK vendor, version, change the installation path if required, and click Download. If you don't have the necessary JDK on your computer, select Add SDK | Download JDK. If the JDK is installed on your computer, but not defined in the IDE, select Add SDK | JDK, and specify the path to the JDK home directory (for example, /Library/Java/JavaVirtualMachines/jdk-12.0.1.jdk). If the necessary JDK is already defined in IntelliJ IDEA, select it from the SDK list. If you don't know which distribution to choose, and you don't have specific requirements that instruct you to use one of the existing distributions, use Oracle OpenJDK. In IntelliJ IDEA, you can download a JDK package right from the IDE, or you can manually download the necessary JDK distribution and define it in the IDE.įor a manual download, use any available distribution that you like, for example: We recommend that you use one of the OpenJDK builds to avoid potential compliance failures. Before you start developing in Java, download and install a standalone JDK build.ĭue to the changes in the Oracle Java License, you might not have the rights to use Oracle's Java SE for free. The bundled JRE is used for running the IDE itself, and it is not sufficient for developing Java applications. The JRE can be obtained separately from the JDK, but it is not suitable for application development, as it doesn't have essential components such as compilers and debuggers. A JDK is a software package that contains libraries, tools for developing and testing Java applications (development tools), and tools for running applications on the Java platform (Java Runtime Environment – JRE). To develop applications in IntelliJ IDEA, you need a Java SDK (JDK). If you want a module to inherit a project SDK, select the Project SDK option from the Module SDK list. If the necessary SDK is already defined in IntelliJ IDEA, select it from the Module SDK list. Select the module for which you want to set an SDK and click Dependencies. In the next dialog, specify the JDK vendor, version, change the installation path if required, and click Download.įrom the main menu, select File | Project Structure | Project Settings | Modules. Only for JDKs: If you don't have the necessary JDK on your computer, select Add SDK | Download JDK. If the SDK is installed on your computer, but not defined in the IDE, select Add SDK | 'SDK name', and specify the path to the SDK home directory. If the necessary SDK is already defined in IntelliJ IDEA, select it from the SDK list. In the next dialog, specify the JDK vendor, version, change the installation path if required, and click Download.įrom the main menu, select File | Project Structure | Project Settings | Project. Only for JDKs: if you don't have the necessary JDK on your computer, select Download JDK. To add an SDK, click, select the necessary SDK and specify its home directory in the dialog that opens. Global SDKįrom the main menu, select File | Project Structure | Platform Settings | SDKs. This folder is called an SDK home directory. Finally, the 64-bit ARM support in JDK 8 is now based on the Linux/AArch64 port as well.Ĭommercial support for the Oracle JDK on 64-bit ARM Linux systems is available through a Java SE Subscription.To define an SDK means to let IntelliJ IDEA know in which folder on your computer the necessary SDK version is installed. Oracle plans to contribute to this port along with ARM, Red Hat and others going forward.īesides introducing the Linux ARM 64 port into JDK 15, the same support for 64-bit ARM systems has also been introduced into JDK 11 with the 11.0.9 October 2020 CPU release. With JDK 12, the OpenJDK developer community decided to focus its resources on a single 64-bit ARM port. The code under the hood comes from the Linux/AArch64 Port for 64-bit ARM systems, which was integrated into JDK 9, along with a separate unified port of HotSpot for 32-bit and 64-bit ARM systems. Oracle JDK 15 binaries for 64-bit ARM systems can be downloaded at the usual download site on OTN, and the corresponding Oracle OpenJDK JDK 15 Linux ARM 64 binary can be downloaded on. As of JDK 15, the list of supported configurations of Oracle JDK includes 64-bit ARM systems running Oracle Linux 7.6 or later.
