Running first example in the book fails

[ivan-brko]

On a system with nothing Scala/sbt specific installed, running java --version gives the following:

openjdk 11.0.9.1 2020-11-04
OpenJDK Runtime Environment (build 11.0.9.1+1-Ubuntu-0ubuntu1.20.10)
OpenJDK 64-Bit Server VM (build 11.0.9.1+1-Ubuntu-0ubuntu1.20.10, mixed mode, sharing)

Running the first example results in following:

./sbt.sh

[blue-tachikoma]

Fixed it by going inside sbt-launch.jar and changing in properties files "http" to "https" + adding an https route for maven central. Or you can just download scala and sbt by yourself, change versions in each project configuration files and it will probably work fine.

Files changed inside sbt-launch.jar:

sbt/sbt.boot.properties
sbt.boot.properties0.7
sbt.boot.properties0.10.0
sbt.boot.properties0.10.1
sbt.boot.properties0.11.0
sbt.boot.properties0.11.1
sbt.boot.properties0.11.2
sbt.boot.properties0.11.3

How to change?
Use winrar, 7zip or other archive manager to open jar (NOT EXTRACTING), modify files in text editor and save (it will probably ask "update archive?", just say yes).

What to change?

• If you see http change it to https
  Expample:
  given string: typesafe-ivy-releases: http://repo.typesafe.com/typesafe/ivy-releases/,[organization]/[module]/[revision]/[type]s/[artifact](-[classifier]).[ext]
  changed: typesafe-ivy-releases: https://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/[revision]/[type]s/[artifact](-[classifier]).[ext]

• if you see maven-central add https route for it
  Expample:
  given string: maven-central
  changed: maven-central: https://repo1.maven.org/maven2
