When a user specifies the wrong email address for their account, an authorization error occurs relating to project.

A savvy person would know that the email is wrong, and I should have re-read the README before blindly hunting. Even if it was my fault, crud in GoogleComputeConstants is distracting, particularly GOOGLE_PROJECT which shows up in grep.

Rather than having curious hard-coded constants, wouldn't it be better to make a special method that says what it does. I understand from @dralves that this is the project for public resources. So far as I can tell, this constant is only used in the compute service adapter for public images.e

Why not just make a method for that and remove the constant, such as we do in aws for the default zone?

   @Delegate
   @Path("/projects/google")
   ImageApi getImageApi(); // or getPublicImageApi

Hi Adrian:

a few things:

• GOOGLE_PROJECT does not refer to the project name (which is not hardcoded as I'll explain next). This constant refers to the "public" project under which certain public resources are, such as public images.
• If you're using "adrian.f.cole@gmail.com" as the account identity then it's the wrong one. refer to the README to find out how to get the right one (something along the lines of my_id@developer.google.com i think). The project name is extracted from the identity (it's the part before the @)
• I never even used the jclouds project (I was using "jclouds-gce").
• please make sure you credentials work by running the oauth live test first (multiple people have tried it)

ok, once you mention what this magic constant does, I'll update the issue accordingly.

[dralves]

as I said it refers to the name of the project under which GCE keeps the "public" resources. It should be documented for dev's sake but there's no reason an user should need or even have to know about it.

[codefromthecrypt]

ok, I agree that this should be better documented, or better yet. removed.

If one enters the incorrect email address, the error relates to the http path including project and that this property is constant is passed as a method arg for project. This is so very unnecessarily confusing.

I'm changing the issue to remove this confusion now and will ping back.

[codefromthecrypt]

ok. changed the issue. you are correct that my google id works, so I'll mention this issue isn't a blocker

[dralves]

So this issue only refers to:

• changing the name of the constant to something like PUBLIC_PROJECT_ID
• documenting it

[codefromthecrypt]

No it refers to deleting the constant and instead expose a no arg method
for ImageApi
