Version 1.6.0_13 of the JVM is not suitable for this product. Version: 1.7 or greater is required.[Solved]

[OS] kali

when I use eclipse for luna, I got the message as below:
Version 1.6.0_13 of the JVM is not suitable for this product. Version: 1.7 or greater is required.

Solve it as below:
step_1: unpack eclipse

$ tar zxvf eclipse-standard-luna-R.tar.gz

step_2: go into the eclipse directory

$ cd eclipse

step_3: delete it's jre directory

$ rm -rf jre/

step_4: run the eclipse

./eclipse

it starts, then the bug has been fixed.

We will configure further for easily use. Steps as below.

step_1: move the eclipse to our pointed directory and change the privilege.

sudo mv eclipse /opt/
cd /opt
sudo chown -R root:root eclipse
sudo chmod -R +r eclipse
sudo chmod +x `sudo find eclipse -type d`

step_6: then create an eclipse executable in my path

sudo touch /usr/bin/eclipse
sudo chmod 755 /usr/bin/eclipse
sudo nano /usr/bin/eclipse

With this contents

#!/bin/sh
export ECLIPSE_HOME="/opt/eclipse"
$ECLIPSE_HOME/eclipse $*

step_7: Then create a gnome menu item

sudo nano /usr/share/applications/eclipse.desktop

With this contents

[Desktop Entry]
Encoding=UTF-8
Name=Eclipse
Comment=Eclipse IDE
Exec=eclipse
Icon=/opt/eclipse/icon.xpm
Terminal=false
Type=Application
Categories=GNOME;Application;Development;
StartupNotify=true

step_8: Configure
You now have a working eclipse.But run this command first to initialise the set up.

/opt/eclipse/eclipse -clean

Then from here on you can run from the menu item applications/programming/eclipse
