Install Sencha Command on Ubuntu 20.04

Sencha Cmd provides several categories of commands and some global switches. In most cases, the first step is to generate an application based on a Sencha SDK such as Ext JS or Sencha Touch

You will also need it to do things like

• Building a new theme for your Ext JS Application.
• Create optimized Javascript code after you made some changes to the RADIUSdesk Ext JS code.

• We assume the following:
  • You have ssh access to a server that already have RADIUSdesk installed
  • There is a user called system with sudo rights

• Update the package index

sudo apt update

• Check if Java is already installed

java -version

• If Java is not currently installed, you’ll see the following output

java -version

Command 'java' not found, but can be installed with:

sudo apt install default-jre            
sudo apt install openjdk-11-jre-headless
sudo apt install openjdk-8-jre-headless 

• Execute the following command to install the default Java Runtime Environment (JRE), which will install the JRE from OpenJDK 11

sudo apt -y install default-jre

• Verify the installation with

sudo apt install default-jre

• You’ll see output similar to the following

openjdk version "11.0.14.1" 2022-02-08
OpenJDK Runtime Environment (build 11.0.14.1+1-Ubuntu-0ubuntu1.18.04)
OpenJDK 64-Bit Server VM (build 11.0.14.1+1-Ubuntu-0ubuntu1.18.04, mixed mode, sharing)

• We need to download and install the Sencha Command in order to build the custom theme for ExtJS.
• Refer to this URL to see which one you will need to download (32 or 64 bit) https://www.sencha.com/products/extjs/cmd-download/
• We have a 64 bit system where we are doing the download and install to.

#Download the Sencha Command zip file
wget https://trials.sencha.com/cmd/7.5.1/no-jre/SenchaCmd-7.5.1.20-linux-amd64.sh.zip
#Install the unzip program
sudo apt-get install unzip
#Unzip the zipfile
unzip SenchaCmd-7.5.1.20-linux-amd64.sh.zip
#Run the installer script
./SenchaCmd-7.5.1.20-linux-amd64.sh

• When you run the installer script you have to accept various EULAs. Selecting the defaults in most cases should be fine.
• These steps are once off steps. Once they are completed we can get our hands dirty by starting with the customization of the theme.
• After you are done you need to ext from the terminal (or SSH) and connect again so that the environment with the patch to the sencha executable is activated.
