What are key differences between sbt-pack and sbt-assembly? -

-

i've stumbled upon sbt-pack plugin. development stream seems steady. it's surprising me believed plugin (quoting sbt-pack's headline) "creating distributable scala packages." sbt-assembly (among other features).

what key differences between plugins? when should use 1 on other?

(disclaimer: maintain sbt-assembly)

sbt-assembly

sbt-assembly creates fat jar - single jar file containing class files code , libraries. evolution, contains ways of resolving conflicts when multiple jars provide same file path (like config or readme file). involves unzipping of library jars, it's bit slow, these heavily cached.

sbt-pack

sbt-pack keeps library jars intact, moves them target/pack directory (as opposed ivy cache live), , makes shell script run them.

sbt-native-packager

sbt-native-packager similar sbt-pack started sbt committer josh suereth, , maintained highly capable nepomuk seiler (also known muuki88). plugin supports number of formats windows msi file , debian deb file. recent addition support docker images.

all viable means of creating deployment images. in cases deploying application web framework etc., might make things easier if you're dealing 1 file opposed dozen.

honorable mention: sbt-progard , sbt-onejar.

this question has answer here: why write “.call(this)” @ end of javascript anonymous function? [duplicate] 4 answers what kind of design pattern , significance of using closure? (function(){ // code here }).call(this); edit then difference between above code , following this keyword still refer same object in both ways. (function(){ // code here })(); thats invoked function expression. more info here: http://benalman.com/news/2010/11/immediately-invoked-function-expression/ the purpose run code while protecting scope (so variables declared within don't leak out global scope. update call sets value of this function being applied on. without it, value set window object, there set outer scope.
