module not found: org.scala-sbt#sbt;1.1.6 - scala

Question

I installed SBT via terminal with following commands:
echo "deb https://dl.bintray.com/sbt/debian /" | sudo tee -a /etc/apt/sources.list.d/sbt.list
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2EE0EA64E40A89B84B2DF73499E82A75642AC823
sudo apt-get update
sudo apt-get install sbt
on my Ubuntu 18.04 and with java version:
openjdk version "1.8.0_171"
OpenJDK Runtime Environment (build 1.8.0_171-8u171-b11-0ubuntu0.18.04.1-b11)
OpenJDK 64-Bit Server VM (build 25.171-b11, mixed mode)
The installation was successful but when I tried to start SBT via terminal, then I've got
https://repo.scala-sbt.org/scalasbt/ivy-snapshots/org.scala-sbt/sbt/1.1.6/ivys/ivy.xml

Answer 1

The root cause is a conflict between openjdk-11-jdk (which is default in Ubuntu 18.04) and sbt packages settings. It has already been fixed in Debian and will be included in Ubuntu shortly. Meanwhile the simplest workaround is to demote your java to version 8. Other solutions employing ca-certificates-java are much more complicated.
First remove conflicting packages:
sudo apt-get remove --purge openjdk* java-common default-jdk
sudo apt-get remove --purge sbt
sudo apt-get autoremove --purge
Check weather you successfully removed all related packages by:
sudo update-alternatives --config java
The system shall prompt you there is no Java available to config, otherwise this workaround fails.
Then reinstall required packages:
sudo apt-get install openjdk-8-jdk sbt
Test by:
sbt compile

Answer 2

Problem is java-certificates so you need to run these commands:
Reinstall JDK
$ sudo apt-get purge openjdk-8-jdk java-common
$ sudo apt-get install openjdk-8-jdk
Run sbt
$ sbt

Answer 3

I would recommend you install Java/Scala/SBT totally independent from the OS packages. It does not matter (or should not matter!) for a developer which specific version of Java was installed by apt-get, yum or whatever.
From the developer's perspective, it may even make sense to test your application under several versions of Java. I've seen this situation before: "it works" under Java 1.8.x but "it fails" under Java 1.8.y.
So, from a developers, perspective, you would be interested on quickly swithing versions of Java, so that you can quickly make sure it works properly under those several different versions, no matter which specific version is installed on your specific version of the OS.
If you liked the idea, this is how it works:
Download manually all JDK versions you like and uncompress them under a given folder under your home folder, say: $HOME/tools. I have a script which automagically installs a certain version of the JDK for you: https://github.com/frgomes/bash-scripts/blob/master/scripts/user-install/install-java.sh
Adjust environment variables in a virtualenv-like fashion. It's easier than you think and you dont't even need virtualenv. All you need is to source a shell script which runs at login time which defines JAVA_HOME, pointing to a given version of Java, under your $HOME/tools. This is an example: https://github.com/frgomes/bash-scripts/blob/master/bashrc-virtualenvs/j8s12/bin/postactivate
Install Scala and SBT versions by hand, or using my automated script at https://github.com/frgomes/bash-scripts/blob/master/scripts/user-install/install-scala.sh

Answer 4

This fixed it for me.
sudo update-ca-certificates -f

Answer 5

In my case, I solved it by removing .m2, .ivy & .sbt.
Next time I executed sbt, it fixed everything.
I believe I broke sbt when I was playing with the cached dependencies or something else.
