Clean install of OdinsonWebapp on Mac OS
Install these if you have not already -- they provide much more functionality than just for Scala/OdinsonWebapp
(1) Ensure Mac command-line-tools is installed:
xcode-select --install
(2) Install Homebrew. In particular, execute the following from the command-line:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
(1) Download Java 8 JDK
(2) After installation, from the command line, verify the java location and version, which should be 1.8 . E.g.,:
claytonm@shadow ~ $ which java
/usr/bin/java
claytonm@shadow ~ $ java -version
java version "1.8.0_172"
Java(TM) SE Runtime Environment (build 1.8.0_172-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.172-b11, mixed mode)
Using Homebrew, execute the following from the command-line:
brew install scala
brew install sbt
(1) clone the OdinsonWebapp repo:
git clone git@github.com:BeckySharp/OdinsonWebapp.git
(2) cd into the root of the repo and run:
cd OdinsonWebapp
sbt webapp/run
That will start the process of downloading all sbt/scala dependencies NOTE: This will take a while and you want a good internet connection Background: sbt and Scala naturally sandbox themselves so that all associated file, include the specific version of sbt and scala that are required by your project, get placed in:
~/.sbt # stores specific version of sbt
~/.ivy2 # stores specific version of scala and project dependencies
When you run sbt for the first time on your project, it uses the project definition to determine the specific version of sbt and scala needed and downloads everything; thereafter, when you run again, it just uses the cached versions.
After successfully downloading everything needed, the call to webapp/run then launches the webapp. The webapp will stay running in the console.
You can now point your browser to localhost:9000 to connect to the webapp html interface.
To STOP the webapp, hit control-c in the terminal.
