Scala 3 Dependencies ↩

This document presents changes in library dependencies for the Scala 3 software distributions.

<style scoped>table { font-size: 80%; }</style>

Introduction

The Scala 3 and Scala 2 software distributions differ in several ways regarding their dependencies on external libraries. We enumerate here the main differences :

• Scala 3 depends on many more external libraries, introduced mainly with the new development of scaladoc.
• Scala 3 depends on compiler-interface, the Scala incremental compiler library (Zinc), originally part of sbt.
• Scala 3 depends on scala-library, the Scala 2.13 standard library (mainly for compatibility with the Scala 2 collection framework).
• Dependencies common to both software distributions include jline (Scala REPL) and scala-asm (JVM backend).

🔎 We observe a jump in the increases in size of the software distributions :

Footnotes ▴

[1] jline 3.21.0 and JNA 5.9.0 Library Updates ↩

Update 3.21.0 of the JLine library and update 5.9.0 of the JNA library make REPL work again on Mac M1 (see pull 9807).

[2] scala-asm Library ↩

Scala 3 and Scala 2 software distributions are packaged differently regarding their dependency on the ASM library (actually a fork of it):

• In Scala 2 scala-asm is hidden into scala-compiler.jar
• In Scala 3 scala-asm is a separate archive file.

We wrote the batch file getasm.bat (~200 lines) to extract the ASM version from the Scala 2 and Scala 3 distributions (using file scala-asm.properties). Here is a sample output :

> getasm run
Found ASM version "7.0.0-scala-1" in Scala 2 installation is "C:\opt\scala-2.12.10"
