How to replace the exported products with the result of an assembly in SBT? -

i using sbt 0.13.15 , sbt-assembly 0.14.5. i'm using assembly task create uber jar contains shaded version of asm no problems. have multi-project build , want other projects in build depend on resulting uber jar instead of compiled class files.

my approach looks this:

exportjars := true  exportedproducts in compile := seq(attributed.blank(assembly.value)) 

unfortunately, sbt hangs indefinitely after output this:

> exportedproducts [info] updating {file:***}... [info] resolving *** ... [info] done updating. [info] compiling ??? java sources ***... [info] packaging *** ... [info] done packaging. 

using jvisualvm can see sbt's main thread waiting elements in queue appear, never happens.

what doing wrong?

edit: here's complete example. in build.sbt:

lazy val root = project   .in(file("."))   .aggregate(foo, bar)  lazy val foo = project   .in(file("foo"))   .settings(seq(     exportjars := true,     exportedproducts in compile := seq(attributed.blank(assembly.value))   ))  lazy val bar = project   .in(file("bar"))   .dependson(foo) 

in project/plugins.sbt:

addsbtplugin("com.eed3si9n" % "sbt-assembly" % "0.14.5") 

in project/build.properties:

sbt.version = 0.13.15 

in foo/src/main/scala/helloworld.scala:

object helloworld  extends app {   println("hello world!") }
