java_valid_versions: Retrieve Valid Java Versions

Description

This function retrieves a list of valid Java versions by querying an appropriate API endpoint based on the chosen distribution. The result is cached for 8 hours to avoid repeated API calls. If the API call fails (for example, due to a lack of internet connectivity), the function falls back to a pre-defined list of Java versions.

Usage

java_valid_versions(
  distribution = "Corretto",
  platform = platform_detect()$os,
  arch = platform_detect()$arch,
  force = FALSE
)

Value

A character vector of valid Java versions.

Arguments

distribution

The Java distribution to download. If not specified, defaults to "Amazon Corretto". Currently only "Amazon Corretto" is supported.

platform

The platform for which to download the Java distribution. Defaults to the current platform.

arch

The architecture for which to download the Java distribution. Defaults to the current architecture.

force

Logical. If TRUE, forces a fresh API call even if a cached value exists. Defaults to FALSE.

Examples

if (FALSE) {
  # Retrieve valid Java versions (cached if available) using Amazon Corretto endpoint
  versions <- java_valid_versions()

  # Force refresh the list of Java versions using the Oracle endpoint
  versions <- java_valid_versions(distribution = "Corretto", force = TRUE)
}
