Install scala to Apple Silicon

Question

I am trying to install scala in MacBook with M1 chips. I have had Zulus javaJDK 15.0.2 installed. I have previously used this page to install home-brew: Getting a warning when installing homebrew on MacOS Big Sur (M1 chip)

But when installing scala by brew install scala, I get the following message:

Error: Failed applying an ad-hoc signature to /opt/homebrew/Cellar/openjdk/15.0.1/libexec/openjdk.jdk/Contents/MacOS/libjli.dylib: /opt/homebrew/Cellar/openjdk/15.0.1/libexec/openjdk.jdk/Contents/MacOS/libjli.dylib: replacing existing signature /opt/homebrew/Cellar/openjdk/15.0.1/libexec/openjdk.jdk/Contents/MacOS/libjli.dylib: resource fork, Finder information, or similar detritus not allowed

==> Caveats ... ... If you need to have openjdk first in your PATH, run: echo 'export PATH="/opt/homebrew/opt/openjdk/bin:$PATH"' >> ~/.zshrc

For compilers to find openjdk you may need to set: export CPPFLAGS="-I/opt/homebrew/opt/openjdk/include"

For the system Java wrappers to find this JDK, symlink it with sudo ln -sfn /opt/homebrew/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk

Despite of this message, I can already run scala script from vscode. So should I worry about the path issue in the message above ? Thanks !

Sorry for inconvenience caused, I will pay attention to it next time. But I have lost the terminal with the message, and I have just noted some lines. I have added them to the description. Thanks. — uru, Mar 06 '21 at 21:12

I successfully installed it using SDKMAN so that is worth a try.

curl -s "https://get.sdkman.io" | bash

Start a new shell or source "$HOME/.sdkman/bin/sdkman-init.sh"

sdk install java
sdk install sbt
sbt compile

Really fast on an M1 with 16GB RAM :)

Mac Book Pro/Air/Mini? – Marius Soutier Mar 04 '21 at 09:03
Mac Mini. But the Pro seems to have about the same performance, presumably because the ARM chip is low power and doesn't need thermal limiting. – Tim Mar 04 '21 at 09:12
Still pondering Mac Mini vs Air, is the Air significantly slower? – Marius Soutier Mar 04 '21 at 09:19

I think the Air is slower, so if you don't need to use it as a laptop then Mini is best :) – Tim Mar 04 '21 at 11:01
I installed zulu version of java. "sdk install java 15.0.2-zulu" then installed sbt and scale. it worked perfectly. – akarca Mar 16 '21 at 09:11
for me (M1 Mini), SDKMAN won't install the right version for the chip even if zulu is specified. SBT fails at runtime – eques Jun 22 '21 at 12:03
Just installed on a new M1 mini and it still works for me :) – Tim Sep 08 '21 at 12:49
