KMP4FREE in 2023
summary
KMP4FREE is a Gradle plugin that lets projects flip between Kotlin JVM and Kotlin Multiplatform with a single-line change, applying multiplatform only when a Gradle flag is true and otherwise proxying to the JVM plugin. It maps main→commonMain and test→jvmTest in memory, preserves JVM test tasks, and can produce an iOS framework on assemble; it reduces risk but notes multiplatform historically breaks configuration cache and doubles task count (7→14). A companion tool KMP Readiness scans dependencies (ran across 450 modules in ~15s) and lists concrete fixes to make modules multiplatform-compatible.
