Download the Eclipse Installer. Eclipse is hosted on many mirrors around the world. Windows, Mac and Linux (Ubuntu): Download and install Eclipse IDE (we recommend to use Eclipse Oxygen 4.7). You might want to create a new workspace for your LSP projects.

Introduction

Installing Eclipse is relatively easy, but does involve a few steps and software from at least two different sources. Eclipse is a Java-based application and, as such, requires a Java Runtime Environment or Java Development Kit (JRE or JDK) in order to run. In this tutorial, we will learn the steps involved in the installation of eclipse on MacOS. MacOS; Login as an administrator on terminal. Installation of Eclipse on MacOS includes several steps described below. 1) Download the latest version. Double-click on the package icon, and follow the instructions to install. When the installation has completed, click on Done. At this point, you may close up the window and drag jdk-8u65-macosx-x64.dmg to the Trash. Installing Eclipse. If you already have Eclipse installed on your Mac, you need to get rid of it.

Eclipse is an integrated development environment (IDE) which provides the platform for computer programming. It is the most used java programming platform which contains a base workspace and provides the programming environment for other languages also like C, C++ via external plugins.

In this tutorial, we will learn the steps involved in the installation of eclipse on MacOS.

Prerequisites

• MacOS
• Login as an administrator on terminal.

Installation

Installation of Eclipse on MacOS includes several steps described below.

1) Download the latest version

This step involves downloading the latest version I.e. eclipse oxygen (by the writing of this tutorial). To install eclipse on our MacOS, we must download the latest version of eclipse by visiting its official website or simply clicking the link http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/oxygen/1a/eclipse-java-oxygen-1a-macosx-cocoa-x86_64.dmg . The downloaded file exists in disk image file(dmg) format which is to be mounted first to get started with the installations.

2) Mount the dmg file

The dmg file which is downloaded from the official website of eclipse needs to be mounted first to the volumes directory. Hdiutil command can be used with the mount option to mount the file into the volumes folder. The process is shown in the image.

3) Copy Eclipse.app into Applications

After mounting the file, Eclipse.app is created inside /Volumes/Eclipse. This is an application file which needs to be copied to the application directory. The file needs to be unmounted after its deployment into the application directory.

4) Unmount the file

Unmounting the file simply involves ejecting the installer. For this purpose, unmount option is used with hdiutil command.

Well, we have successfully installed Eclipse oxygen on our MacOS.

Install Python and Java before installing Eclipse.

You may want to print these instructions before proceeding, so that you can refer to them while downloading and installing Eclipse. Or, just keep this document in your browser. You should read each step completely before performing the action that it describes. This document shows downloading and installing Eclipse on Windows 7 in Winter 2017.

Eclipse: (Neon)

The Eclipse download requires about 250 MB of disk space; keep it on your machine, in case you need to re-install Eclipse. When installed, Eclipse requires an additional 250 MB of disk space.

Downloading

1. Click Eclipse

   The following page will appear in your browser. In this handout we will download Eclipse IDE for Eclipse Committers for Windows 32 Bit; if your computer uses Windows, continue below; otherwise choose either Mac Cocoa or Linux instead.

   It is critical that Java, Python, and Eclipse are either all 32 Bit or are all 64 Bit (and only if your Machine/OS supports 64 Bit): I think it easiest to use 32 Bit for everything.

2. Click the 32-Bit (after Windows) to the right of the Eclipse IDE for Eclipse Committers.

   You will see the following page (don't worry about the name of the institution underneath the orange DOWNLOAD button).

3. Click the orange DOWNLOAD button. The site named here, in orange to the right of the button: Canada - University of Waterloo Computer Science Clupb (http) is the random one chosen by the download page this time; yours may differ.

   This file should start downloading in your standard download folder, while showing a splash screen about donating to Eclipse. This file is about 250 Mb so it might take a while to download fully if you are on a slow internet connection (it took me about 5 minutes over a cable modem). Don't worry about the exact time as long as the download continues to make steady progress. In Chrome progress is shown on the bottom-left of the window, via the icon

   The file should appear as

   Terminate the window browsing the Eclipse download.

4. Move this file to a more permanent location, so that you can install Eclipse (and reinstall it later, if necessary).
5. Start the Installing instructions directly below.

Installing (for Python)

Python and Java should be installed before installing Eclipse

1. Unzip eclipse-committers-newon-2-win32.zip, the file that you just downloaded and moved.
   On my machine (running Windows 7), I can
   • Right-click the file.
   • Hover over the IZArc command from the menu of options.
   • Click Extract Here

   If you do not have IZArc or an equivalent unzipping program, here is the web site to download a free copy of IZarc.

   Unzipping this file creates a folder named eclipse; unzipping 250 MB can take a few minutes. You can leave this folder here or move it elsewhere on your hard disk. I recommend putting the downloaded file and resulting folder in the C:Program Files directory.

2. Create a shortcut on your desktop to the eclipse.exe file in this eclipse folder:
   On most Windows machines, you can
   • Right-press the file eclipse.exe
   • Drag it to the desktop.
   • Release the right button.
   • Click Create shortcut here

   Now you are ready to perform a one-time only setup of Eclipse on your machine.

3. Double-click the shortcut to Eclipse that you just created above.

   The following splash screen will appear

   and then an Eclipse Launcher pop-up window will appear.

   In the Workspace text box, your name should appear between C:Users and workspace, instead of Pattis.

   Leave unchecked the Use this as the default and do not ask again box. Although you will use this same workspace for the entire quarter (checking projects in and out of it), it is best to see this Workspace Launcher pop-up window each time you start Eclipse, to remind you where your workspace is located.

   In fact, it is a good idea to create on your desktop a shortcut to your workspace folder; but you must click OK (see below) before Eclipse creates this folder and you can create a shortcut to it.

4. Click OK.

   Progress bars will appear as Eclipse loads.

   Eventually the Eclipse workbench will appear with a Welcome tab covering it.

5. Terminate (click X on) the Welcome tab.

    The Eclipse workbench will now have only the PyDev icon here and will look like

23. Locate the workspace folder created in step 3 (see C:Usersyournameworkspace) and download the courselib.zip file into this workspace and unzip it there, producing the courselib folder; it should should contain a bunch of Python module files (ending in .py). From time to time you will be asked to put other course-specific Python module files into this courselib folder; these modules will be usable in all Python projects in Eclipse.
24. Inform Eclipse to use the courselib folder in all Python projects.
    • Select Window | Preferences.
