The BFG is written in Scala, a modern functional language that runs on the JVM - so it can run anywhere Java can.
Here's a rough set of instructions for building the BFG, if you don't want to use the pre-built downloads:
- Install Java 6 or above
- Install sbt
git clone [email protected]:rtyley/bfg-repo-cleaner.git
cd bfg-repo-cleaner
sbt
<- start the sbt consolebfg/assembly
<- download dependencies, run the tests, build the jar
To find the jar once it's built, just look at the last few lines of output from the
assembly
task - it'll say something like this:
[info] Packaging /Users/roberto/development/bfg-repo-cleaner/bfg/target/bfg-1.11.9-SNAPSHOT-master-21d2115.jar ...
[info] Done packaging.
[success] Total time: 19 s, completed 26-Sep-2014 16:05:11
If you're going to make changes to the Scala code, you may want to use IntelliJ and it's Scala plugin to help with the Scala syntax...!
If you use Eclipse IDE, you can set-up your development environment by following these instructions:
- Install
sbt
and build as-above - Install Scala IDE for Eclipse into your Eclipse installation if not already installed
- Add the
sbteclipse-plugin
to your set of local sbt plugins:
mkdir -p ~/.sbt/0.13/plugins && tee ~/.sbt/0.13/plugins/plugins.sbt <<EOF
addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "4.0.0")
EOF
sbt
<- start the sbt consoleeclipse
<- first-time only setup of the Eclipse plugineclipse
<- again, generate Eclipse project files (note that these are.gitignore
d)- In Eclipse,
File -> Import -> Existing Projects into Workspace
, browse to yourbfg
working-copy, and ensure that you selectSearch for nested projects
- You should now have the 4
sbt
projects imported into your Eclipse workspace.
I personally found Coursera's online Scala course very helpful in learning Scala, YMMV.
