Method Summary

Modifier and Type	Method	Description
static @Nullable File	detectExecutableOnPath(@NotNull String executableName)	Detects the executable home directory and validates that it matches the required pattern using existsInHomeBinExePattern(String, String)
static boolean	existsInHomeBinExePattern(@Nullable String homePath, @NotNull String executableName)	Validates that the executable exists at the path ${homePath}/bin/${executableName} Appends ".bat" to the executable name if the platform is Windows
