Compile feilure - device.proto: File not found

I am trying to setup following instructions and I get errors on mvn compile package.

[Fleker]

Can you place the device.proto and homegraph.proto to the applicable directory structure src/main/proto/google/home/graph/v1?

[thgbarros]

I thought that these files were to stay in src/main/proto.

Now I have a new failure:

Hmm the error:

cannot find symbol
[ERROR]   symbol:   class Generated
[ERROR]   location: package javax.annotation

seems to suggest that the project hasn't imported javax.annotation, although other errors seem to point to build files that were generated multiple times.

It is good that you got past the first error, but that indicates the documentation needs to be improved.

[ldgmaia]

I'm getting the same error:

[ERROR] symbol: class Generated [ERROR] location: package javax.annotation

Actually I had to fix some other stuff (changing "&&" to ";", for example) by following the instructions. I think a setup instructions update will be good.

[Fleker]

If you can make specific changes and open a pull request, that'll be helpful. It's unusual that folks encounter issues, as I haven't had any build issues when running the sample.
