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.
