This page provides step-by-step instructions for how to provision a dedicated development environment for the complete set of projects that comprise the Eclipse Platform's SDK, i.e., the projects used to build the downloads of the Eclipse Platform Project. The provisioning process is entirely automated, except for course from user input to choose configurable options, e.g., where in the file system to place the installation, but even for these, defaults are provided.

Launch the Eclipse Installer

If you don't already have the Eclipse Installer on your system, download the installer that is appropriate for your operating system's architecture. For Windows, the installer is distributed as an executable. It will start without a JRE or JDK installed, but if you don't have at Java 8 installed, it will guide you to install that. For Mac and Linux, you must unpack the installer before you can run the application. In all cases, you must install a JRE or JDK (currently at least Java 8) before you can successfully use the installer, and of course the installation you will create needs it too. Please look at these instructions if you need further details. And note that on Mac you must install a JDK, not merely a JRE.

Now launch the installer application. Unless you just downloaded a new installer, the one you have probably needs to be updated. In simple mode, you'll see a "!" indicator on the menu button in the upper right corner; the menu will have an update item to start an update. In advanced mode, the right-most toolbar button at the bottom can be pressed to start an update.

Apply the Platform SDK Configuration

We will use a so-called Oomph configuration to automate the selection of the product and projects to provision. Drag and drop the Platform SDK Configuration link on the title area of the installer. If the installer is in simple mode, it will ask to Switch to Advanced Mode; confirm that prompt. When the configuration is successfully applied, the installer will be in advanced mode and will automatically turn to the Variables page. As an alternative to drag-and-drop, you can copy the Platform SDK Configuration link, and apply it to the installer. In advanced mode, this is done via the menu action; this action will appear in the menu only if the clipboard contains a valid configuration:

In simple mode, this is done via the left-most button in the toolbar; this button will appear in the toolbar only if the clipboard contains a valid configuration:

Note that the installer will by default use a shared bundle pool for creating installations. This defaults to the .p2 folder in the home folder. If the file system for the home folder is relatively small, you can change the default location using the Bundle Pools menu option in simple mode, or the right-most toolbar button in the Bundle Pool section in advanced mode, as seen in each of the corresponding screen captures above.

Note also that you can choose which Java VM is used by the installation you are about to create. The installer will generally detected the JREs and JDKs installed on your system, choosing an appropriate default, and remembering it for the next time you use the installer. But failing that, the installer will stay on the product page and you must use the tool button to locate a Java VM that is suitable for the installation being created.

Review the Variables

After applying the configuration, you'll be on the variable page of the install wizard's advanced mode:

Of course you can use the Back button to review the selections that were made on the previous two pages, i.e., on the product page and the projects page. If this is the first time you've used the installer, there will be large number of variables, but all have suitable defaults. Of particular note, you may wish to change the "Root install folder" to a different location, it defaults to your home folder, keeping in mind that this location will use a significant amount of disk space. The three so-called location rule variables, for this tutorial's example scenario, will create the installation in D:\sandbox\USER-HOME-CLEAN\platform-sdk\eclipse ( on Mac), the workspace in D:\sandbox\USER-HOME-CLEAN\platform-sdk\ws, and all the Git clones under D:\sandbox\USER-HOME-CLEAN\platform-sdk\git.

The long list of variables is mostly the result of the different choices available for the URI used to clone each Git repository. Currently there are six choices, but that may soon be reduced to three if the Eclipse Foundation eliminates the non-Gerrit servers. All the clone URIs for the Platform SDK Configuration's repositories default to anonymous, read-only Gerrit access. If you are a committer, or a contributor with a Gerrit account, you will want to change each of these URIs to a form that allows read-write access. If you do not have a Gerrit account, you should get one immediately! When you select the SSH (read-write, Gerrit) choice, a new variable prompt, Eclipse Git/Gerrit user ID, will appear at the very bottom. Here you should enter your Eclipse account ID, e.g., for me, emerks. Note that if you find it very painful to change each of the many URIs in the dialog, you'll only ever have to do this once, because the installer will remember this choice and will no longer display the variable, unless you check Show all variables, in which case you can change the choice you made previously.

Press the Next button.

Confirm the Tasks

After pressing the Next button, you'll be on the Confirmation page:

Here you can see all the setup tasks that must be performed before the installation can be launched. You can select each task to review its nested element structure and its properties; you can also select a nested elements to review its properties. The most important task is the so-called p2 task, it specifies the requirements of what needs to be installed and the update sites from which to install them. Note in particular that the Platform SDK Configuration will install using the Eclipse Platform Project's most recent Integration build.

Press the Finish button and accept the license that is likely associated with the features you are about to install.

Monitor the Progress

After pressing the Finish button, you'll be on the progress page where you can review the progress of the tasks being performed.

After the p2 task' repositories are loaded, when it's time to download the artifacts to install, you'll likely be prompted to accept all the specific licenses. Note that this confirmation dialog has a "Remember accepted licenses" check box, be sure to click it so that you'll never be asked to review this license again.

If this is the first time you've created an installation using the installer you may wish to go for a quick coffee break while the artifacts download. Be sure the Launch automatically check box is checked so that the installation will automatically launches upon completion (in case your coffee break turned out to be longer than expected). Unfortunately the platform's integration build is not mirrored, and there are frequent new builds, so this process can take a while. Also the server sometimes gets overloaded, so if there is a timeout failure, you can press the Back button, followed by the Finish button, to resume downloading.

Provision the Workspace

When you get back from your coffee break, the installation will have launched and the setup engine will be working hard to provision its workspace. Note that there will be an animated button at the bottom of the window, near the right-hand side. You can press that control to bring up the Updater dialog, so you can review the progress of provisioning the workspace:

There's nothing else you need to do. Cloning all these repositories will definitely take some time, some are very large, and the update sites might be slow, so you can go on your lunch break now because this could take 90 minutes.

Review the Result

The end result is a workspace like this:

All the projects are organized into sensible working sets. All the Git clones are Gerrit enabled for easy contribution. And the setup even created a feature-based "Runtime Workspace" launcher and added it to the favorites list, so it's already in the menu. Now you can make changes to any project to fix bugs or to add new features and you can launch a runtime instance to test any of your changes.

Note that PDE's target platform for this workspace also contains binary equivalents of all projects in the workspace, so you can close any combination of projects to improve build time without causing compile errors.
