Locking asset configuration with GCV does not work if subprojects define their own repos

[fawind]

What happened?

There seems to be a bug introduced by #1012.

While writing locks for an assetBundle, sls-packaging is not respecting repository overrides defined in the bundle project. E.g. the case where we discovered this, the asset dependency gets resolved through a local maven repo that's checked in into the git repo.

A workaround is to add the repository to the root build.gradle. For example:

allprojects {
  repositories {
    maven { url project(':my-local-project').file('maven' )}\
  }
}
