Parallelize resolution of dependencies based on projects when resolving only third party

[raviagarwal7]

Since multiple configurations on the same project cannot be resolved simultaneously adding the ability to parallel resolve deps by utilizing all the available projects.

// okbuck config
okbuck {
    externalDependencies {
        // enables exported deps resolution
        enableExportedDeps = true
        // only resolves third party deps
        thirdPartyResolutionOnly = true
   }
}

// settings.gradle
include ":tooling:gradle"
include ":tooling:gradle:dummy1"
include ":tooling:gradle:dummy2"
include ":tooling:gradle:dummy3"
include ":tooling:gradle:dummy4"
include ":tooling:gradle:dummy5"

// Add a simple build.gradle file to each dummy project
apply plugin: "java"

Now the above setup will make a total of 8 projects available to grade (root-project, :tooling, and the ones defined explicitly) which will be able to parallelize resolving configurations on up to 8 threads.
