Why does build fail due to missing apklib dependency with custom local repository?

Question

I have a Scala/Android project that I compile with SBT 0.12.4. It works.

I can declare a new repository and new apklib dependency:

resolvers +=  "local maven" at "file:./lib/"
libraryDependencies += apklib("com.sbstrm" % "appirater" % "1.3.1")

I've got the following files in ./lib/ of my project's root (that corresponds to the local maven resolver's definition):

Under com/sbstrm/appirater

• _maven.repositories
• appirater-1.3.1.apklib
• appirater-1.3.1.pom

and in com/sbstrm/appirater/1.3.1:

• maven-metadata-local.xml

The issues come when I upgrade sbt to 0.13.6.

With the version I'm getting the following errors and I can't embed the appirater library anymore in my project:

[error] (*:update) sbt.ResolveException: unresolved dependency: com.sbstrm#appirater;1.3.1: URI is not hierarchical

Does anyone have a solution?

Answer 1

tl;dr Use ${baseDirectory.value} to reference the project's main directory, i.e. resolvers += "local maven" at s"file:${baseDirectory.value}/lib".

The issue comes from the line resolvers += "local maven" at "file:./lib/" because the preconditions on the parameter do not hold, i.e. "file:./lib/" doesn't meet java.io.File's contract.

You can check it out yourself in Scala REPL:

new java.io.File(new java.net.URI("file:./lib/"))

With the above line you'll face the error:

scala> new java.io.File(new java.net.URI("file:./lib/"))
java.lang.IllegalArgumentException: URI is not hierarchical
  at java.io.File.<init>(File.java:418)
  ... 43 elided

The solution is to use ${baseDirectory.value} to fully reference the path of the main directory of the project:

resolvers +=  "local ./lib maven" at s"file:${baseDirectory.value}/lib"
