Scala / SBT - dependency not allowed on PaaS (cloudControl & heroku)
I have a simple application Scala
built with spray.io . I am using Scala 2.11.2
and SBT 0.13.0
. All my dependencies are listed here:
libraryDependencies ++= Seq(
"com.typesafe.akka" %% "akka-actor" % "2.3.6",
"com.typesafe.akka" %% "akka-slf4j" % "2.3.6",
"io.spray" % "spray-can_2.11" % "1.3.2",
"io.spray" % "spray-routing_2.11" % "1.3.2",
"io.spray" % "spray-json_2.11" % "1.3.1"
)
libraryDependencies += "org.mongodb" %% "casbah" % "2.7.2"
libraryDependencies += "com.stormpath.sdk" % "stormpath-sdk-api" % "1.0.RC4.2"
libraryDependencies += "com.stormpath.sdk" % "stormpath-sdk-httpclient" % "1.0.RC4.2"
When building and running locally everything is fine, but when I try to push / deploy it on platforms PaaS
like cloudControl or heroku I get below dependency problem:

Checking my dependencies with sbt-dependency-graph shows that not resolved org.apache.httpcomponents:httpclient
is a nested dependency com.stormpath.sdk:stormpath-sdk-httpclient:1.0.RC4.2
.
The variable is ${httpclient.version}
not resolved at build time for some reason , but that's all I can figure out here. Please, help!!!

I'm not sure what's going on. But eliminating the transitive dependency and adding it to SBT explicitly seems to fix the problem, at least the unresolved dependency issue:
libraryDependencies += "com.stormpath.sdk" % "stormpath-sdk-httpclient" % "1.0.RC4.2" exclude("org.apache.httpcomponents","httpclient")
libraryDependencies += "org.apache.httpcomponents" % "httpclient" % "4.2.2"
But keep in mind that we don't know which version of apache httpclient is stormpath-sdk-httpclient
used in compiling it, so you can run runtime related paths / bindings of bound exceptions. If this happens, I recommend asking the developers stormpath-sdk-httpclient
.
EDIT:
you can see the version they were used in: https://github.com/stormpath/stormpath-sdk-java/blob/master/pom.xml#L98
