java - How to set a variable in INSTALL4j during the installation to make it available in the .exe file after installation

问题描述

I made using install4j IDE. During the installation, I want to be able to assign a variable and make it available for the .exe file when the installation is complete.

Simplified scenario:

  1. A user provides his name in the form while running the installer.
  2. Installation process finished.
  3. A user executes the created .exe file
  4. Application Greets the user with: Hello {name provided in step 1.}

What is the best way to achieve that?

All form components that take user input, for example the "Text field" form component bind the input to an installer variable that is automatically registered as a response file variable.

For example, if the configured variable is "myName", then in your launcher you can retrieve the entered value via

com.install4j.api.launcher.Variables.getInstallerVariable("myName")

For other installer variables that are not filled by form components, you can call

context.registerResponseFileVariable("otherVariable");

in a "Run script" action to make them available in the same way in your launchers.
