Install eclipse in Ubuntu

I wrote a Linux article about how to configure eclipse a long time ago. I used to post it on a school forum. Now, I also put it here, which is an aggregate resource.

1. First of all, download the eclipse compressed package. Here I download the version 3.1.2
Eclipsesdk3.1.2: Click to download eclipse-SDK-3.1.2
Since I mainly use eclipse for Java learning, I just downloaded the following plug-ins. Note that the use of VE must be used with the EMF and GEF of a specific version.
Emf2.1.0: Click to download emf-2.1.0
Gef3.1: Click to download gef-3.1
Ve1.1.0: Click to download ve-1.1.0
Of course, if you want to write a C/C ++ program, you can download the following plug-in.
Cdt3.0.2: Click to download cdt-3.0.2
2. Let's talk about a relatively easy-to-use method:
You only need to decompress the downloaded eclipsesdk package and the package of each plug-in any folder to use eclipse. First, go to the directory with a compressed package,
$ CD/directory of the downloaded eclipse-sdk-3.1.2-linux-gtk.tar.gz compressed file
Run the following command:

$ Sudo tarxvfz eclipse-SDK-3.1.2-linux-gtk.tar.gz-C/OPT
$ Sudo unzip-D/OPT emf-sdo-runtime-2.1.0.zip
$ Sudo unzip-D/OPT GEF-runtime-3.1.zip
$ Sudo unzip-D/OPT VE-SDK-1.1.0.1.zip
$ Sudo tarxvfz org.eclipse.cdt-3.0.2-linux.x86.tar.gz-C/OPT

At this time, you can see an eclipse folder in the/OPT folder. Double-click the eclipse file to run eclipse.
If you want to see the eclipse option in the menu bar, you can write the following file:
$ Gedit ~ /. Local/share/applications/eclipse-user.desktop
[Desktop entry]
Comment = Java ide
Name = eclipse
Exec =/opt/Eclipse/eclipse
Encoding = UTF-8
Terminal = false
Type = Application
Categories = application; development;
Icon =/opt/Eclipse/icon. XPM
This method of installing eclipse is fast and convenient. The disadvantage is that the plug-in is not easy to manage. Because they all decompressed to the plugins and features folders and mixed them together.
3. An installation method that facilitates plug-in management and accelerates eclipse startup loading (although tedious, mongo_^ is recommended)

$ Sudo mkdir/opt/Eclipse/Links
$ Sudo mkdir/opt/Eclipse/Addons

The links directory stores the. Link file pointing to each plug-in, and the Addons directory stores each plug-in.

$ Sudo mkdir/opt/Eclipse/Addons/EMF
$ Sudo mkdir/opt/Eclipse/Addons/GEF
$ Sudo mkdir/opt/Eclipse/Addons/ve
$ Sudo mkdir/opt/Eclipse/Addons/CDT

The above command creates a directory for storing various plug-ins

$ Sudo unzip-D/opt/Eclipse/Addons/EMF emf-sdo-runtime-2.1.0.zip
$ Sudo unzip-D/opt/Eclipse/Addons/GEF GEF-runtime-3.1.zip
$ Sudo unzip-D/opt/Eclipse/Addons/ve VE-SDK-1.1.0.1.zip
$ Sudo tarxvfz org.eclipse.cdt-3.0.2-linux.x86.tar.gz-C/opt/Eclipse/Addons/CDT

The above command decompress the compressed packages of each plug-in to the corresponding directory. Next, you need to generate an empty. eclipseextension file in the eclipse directory of each plug-in.

$ Sudo VI/opt/Eclipse/Addons/EMF/Eclipse/. eclipseextension
$ Sudo VI/opt/Eclipse/Addons/GEF/Eclipse/. eclipseextension
$ Sudo VI/opt/Eclipse/Addons/ve/Eclipse/. eclipseextension
$ Sudo VI/opt/Eclipse/Addons/CDT/Eclipse/. eclipseextension

Next, go to the links directory and create a. Link file for each plug-in.

$ Sudo gedit/opt/Eclipse/links/EMF. Link
Path =/opt/Eclipse/Addons/EMF
$ Sudo gedit/opt/Eclipse/links/GEF. Link
Path =/opt/Eclipse/Addons/GEF
$ Sudo gedit/opt/Eclipse/links/ve. Link
Path =/opt/Eclipse/Addons/ve
$ Sudo gedit/opt/Eclipse/links/CDT. Link
Path =/opt/Eclipse/Addons/CDT

If you want to see the eclipse option in the menu bar, you can write the following file:
$ Gedit ~ /. Local/share/applications/eclipse-user.desktop
[Desktop entry]
Comment = Java ide
Name = eclipse
Exec =/opt/Eclipse/eclipse
Encoding = UTF-8
Terminal = false
Type = Application
Categories = application; development;
Icon =/opt/Eclipse/icon. XPM
After starting eclipse in this way, if eclipse does not recognize these plug-ins, you can set the path of each plug-in help> Software Updates> Manage configuration.
Success! ^_^ Haha
