Gradle is a powerful build automation tool that allows defining build-time variables in the build.gradle file and accessing them in Java code.
One approach involves generating a Java class during the build process containing static constants initialized with Gradle-defined values, making them available at compile-time.
Another approach is to write Gradle variables into a properties file that can be read by an application at runtime, ideal for apps requiring configurable environments.
For dynamic environment configurations, variables can be injected as system properties during application launch, providing runtime availability without additional files or generated code.
