使用gomobile绑定完整的Go项目

I am trying to have my Smartphone run a hyperledger-burrow-client. Therefore, I would need to compile the burrow project (written in Go) into a .jar and .aar file. I am using gomobile but the problem is that I can not figure out how to compile complete projects with gomobile. I downloaded the repository and then I run gomobile bind -o some-file path_to_burrow_project. Unfortunately I get this error:

gomobile bind -o app/burrow-bc.aar github.com/hyperledger/burrow
gomobile: package "github.com/hyperledger/burrow": no buildable Go source files in /home/debbi/Documents/go/projects/src/github.com/hyperledger/burrow

Can anyone maybe help me with compiling the complete project into a library for android?
