Visual Studio Code - The supported IDE for 2019 and later robot code development. The minimum supported macOS version is Mojave (10.14.x). Connect to your Managed/Pay-As-You-Go MacinCloud Server through the Portal.Important. Multi-Currency and Payment Methods Now Available. ProGuard (for Android Builds) Upgraded to v5.3.2 on VSTS Agent Servers. Azure Build (VSTS) Agent Server is now macOS Mojave and Visual Studio for Mac v8.0.9.5.Getting the Source CodeOpenJDK uses Mercurial for source control. See for instance OpenJDK installation for some methods of installing a prebuilt OpenJDK. Building it requires a certain amount of technical expertise, a fair number of dependencies on external software, and reasonably powerful hardware.If you just want to use OpenJDK and not build it yourself, this document is not for you. IntroductionOpenJDK is a complex software project. Follow the instructions, and try running bash configure again.If any of these steps failed, or if you want to know more about build requirements or build functionality, please continue reading this document.
If you want to build an older version, e.g. At the OpenJDK Mercurial server you can see a list of all available forests. To assist you in dealing with this somewhat unusual arrangement, there are multiple tools available, which are explained below.In any case, make sure you are getting the correct version. You will need to check out all of the repositories to be able to build OpenJDK. Visual Studio Jdk How To Check OutChances are the build will not work. Special ConsiderationsFor a smooth building experience, it is recommended that you follow these rules on where and how to check out the source code.Do not check out the source code in a path which contains spaces. The rest of this document assumes a working knowledge of Mercurial. Microsoft paint like application for macIf you need to use a network share for the source code, see below for suggestions on how to keep the build artifacts on a local disk.On Windows, extra care must be taken to make sure the Cygwin environment is consistent. The build process is very disk intensive, and having slow disk access will significantly increase build times. Chances are you will hit an OS limitation during the build.Put the source code on a local disk, not a network share. Using hgforest.shThe hgforest.sh script is more expressive than get_source.sh. Any subsequent execution of the script will update all sub-repositories to the latest revision. That is, do not use another Mercurial client such as TortoiseHg.Failure to follow this procedure might result in hard-to-debug build problems.The simplest way to get the entire forest is probably to clone the top-level repository and then run the get_source.sh script, like this: hg clone The first time this is run, it will clone all the sub-repositories. This is especially important if your user name contains spaces and/or mixed upper and lower case letters.Clone the OpenJDK repository using the Cygwin command line hg client as instructed in this document. This will ensure that it will have proper Cygwin attributes, and that it's children will inherit those attributes.Do not put the OpenJDK clone in a path under your Cygwin home directory. That is, do not create it using Windows Explorer. Here's one way to do this: cd ~The trees extension needs to know the structure of the forest. Installing the ExtensionInstall the extension by cloning and updating your. More information is available on the Code Tools trees page. The get_source.sh script is basically a simple wrapper that runs either hgforest.sh clone or hgforest.sh pull -u.Pulling and updating the forest: bash common/bin/hgforest.sh pull -uMerging over the entire forest: bash common/bin/hgforest.sh mergeThe trees extension is a Mercurial add-on that helps you deal with the forest. Building on x86At a minimum, a machine with 2-4 cores is advisable, as well as 2-4 GB of RAM. For instance, to update the entire forest: hg tpull -u Build Hardware RequirementsOpenJDK is a massive project, and require machines ranging from decent to powerful to be able to build in a reasonable amount of time, or to be able to complete a build at all.We strongly recommend usage of an SSD disk for the build, since disk speed is one of the limiting factors for build performance. Tcommit, tstatus or tmerge. Other OperationsThe trees extensions supplement many common operations with a trees version by prefixing a t to the normal Mercurial command, e.g. Like this: hg tclone In this case, the forest will be properly initialized from the start. Support for other operating system, e.g. Operating System RequirementsThe mainline OpenJDK project supports Linux, Solaris, macOS, AIX and Windows. Instead, see the section on Cross-compiling. Building on arm/aarch64This is not recommended. (The more cores to use, the more memory you need.) At least 8 GB of free disk space is required. Building on sparcAt a minimum, a machine with 4 cores is advisable, as well as 4 GB of RAM. From time to time, this is updated by the community to list successes or failures of building on different platforms. Operating systemOracle Enterprise Linux 6.4 / 7.1 (using kernel 3.8.13)Mac OS X 10.9 (Mavericks) / 10.10 (Yosemite)The double version numbers for Linux, Solaris and macOS is due to the hybrid model used at Oracle, where header files and external libraries from an older version is used when building on a more modern version of the OS.The Build Group has a wiki page with Supported Build Platforms. Such information is always subject to change, but this table is up to date at the time of writing.
