Building a Plug-and-Play JVM Compiler for Android and Desktop with Bytesmith

What if adding Kotlin and Java compilation to your application didn't mean building an entire compilation pipeline yourself? What if you could add Bytesmith, configure the filesystem once, provide your source files and output destination, and simply compile? That's the idea behind Bytesmith . Bytesmith is a Kotlin and Java compiler toolkit designed for JVM and Android applications. It provides a unified API for Kotlin, Java, and mixed-language compilation, while also supporting filesystem abstraction, custom classpaths, boot classpaths, compiler plugins, packaging, and diagnostics. Configure the environment, provide the source, specify the output, and compile. The problem Compiler tooling can become surprisingly difficult when it is tightly coupled to the environment in which it was originally designed to run. You might need to deal with: Kotlin compiler versions Kotlin standard libraries Java compilation Bootclasspath configuration Dependency classpaths Source discovery Output handling Android storage Storage Access Framework URIs Packaging Compiler diagnostics And then there is the question of where those files actually live. On a desktop JVM, you might have traditional filesystem paths: /home/user/project/src/Main.kt On Android, you might be working with application storage or files selected through the Storage Access Framework: content://... If your compiler API directly depends on java.io.File , your compilation code becomes coupled to one filesystem model. Bytesmith takes a different approach. Adding Bytesmith The goal is to make compilation something you can plug into an application. With Gradle: implementation ( "io.github.sifisofakude.bytesmith:bytesmith-common:1.0.0" ) After adding Bytesmith, configure the filesystem your application wants to use. For a JVM application: FileSystems . current = JvmFileSystem () For Android: FileSystems . current = AndroidSafFileSystem ( context ) Once the filesystem is configured, the rest of the compilation layer can opera
