See this blog post here, for step-by-step instructions.

The process is documented step-by-step and in the comments the author has included a script -

#!/bin/sh

ECLIPSE=/usr/lib/eclipse/eclipse

inject_update_site(){
if [ ! -e "$1" ] ; then
echo "W: Cannot find $1" 2>&1
return 1
fi
cat - >>"$1" <<EOF
repositories/http\:__download.eclipse.org_releases_indigo/enabled=true
repositories/http\:__download.eclipse.org_releases_indigo/isSystem=false
repositories/http\:__download.eclipse.org_releases_indigo/nickname=Indigo Update Site
repositories/http\:__download.eclipse.org_releases_indigo/uri=http\://download.eclipse.org/releases/indigo/
EOF

}

if [ ! -d ~/.eclipse/ ] ; then
$ECLIPSE -clean -initialize || exit $?
artifact=$(find ~/.eclipse \
-regex .*/profileRegistry/.*/org.eclipse.equinox.p2.artifact.repository.prefs)
metadata=$(find ~/.eclipse \
-regex .*/profileRegistry/.*/org.eclipse.equinox.p2.metadata.repository.prefs)
if [ -z "$artifact" ] || [ -z "$metadata" ]; then
echo "W: Cannot inject update-sites, cannot find the correct config." 2>&1
else
( inject_update_site "$artifact" && \
inject_update_site "$metadata" && \
echo "I: Injected update sites" ) || echo "W: Could not inject update sites." 2>&1
fi
fi

exec $ECLIPSE "$@"

which works.

Step 1 » Install java JDK or JRE

sudo apt-get install openjdk-7-jdk

Step 2 » Download latest copy from here http://www.eclipse.org/downloads/?osType=linux

Step 3 » Move the downloaded package to /opt directory

sudo mv eclipse-SDK-4.2.2-linux-gtk.tar.gz /opt

Step 4 » Extract the package

sudo tar -xvf /opt/eclipse-SDK-4.2.2-linux-gtk.tar.gz -C /opt

Step 5 » Create a new desktop file eclipse.desktop in /usr/share/applications/ and add the below lines .

[Desktop Entry]
Name=Eclipse 
Type=Application
Exec=/opt/eclipse/eclipse
Terminal=false
Icon=/opt/eclipse/icon.xpm
Comment=Integrated Development Environment
NoDisplay=false
Categories=Development;IDE
Name[en]=eclipse.desktop

Step 6 » Simply drag this eclipse.desktop file to the launcher.

Make sure to cd to the /opt folder before executing the tar command. If you don't then the tar command will create the eclipse directory in whatever your current directory is.

After installing java JDK or JRE run the following command and it'll install eclipse for you,

sudo apt-get install eclipse
