gRPC backend doesn't compile

[SueDunome]

I've been at this a while and I am stuck. Please advise. Thankyou.

With a new, unedited clone:

git clone https://github.com/GoogleCloudPlatform/abelana/

The documentation says:

https://cloud.google.com/solutions/mobile/image-management-mobile-apps-grpc

"Launch a local gRPC backend and create Datastore indexes"

" 5. Launch the server."

                    $ ./gradlew execute

When I do this, I get the following error. This means that I can not run the sample project. Is something broken?

Ubuntu replaced sh with dash, which doesn't appear to be compatible with the generated script. Your options are to either manually call the script that resides inside the build folder after you execute gradle, or edit the execute task inside the gradle build file to execute using bash. You could also just point to the file and let the environment determine what it should use by what is specified in the head (which is bash) in case you switch environments often.

so either call it directly with some variation of
./abelana-grpc-server

Or edit the gradle build task to something like

task execute(type: Exec) {
    commandLine "bash build/distributions/$project.name-$version/bin/$project.name".split()
}

or even

task execute(type: Exec) {
    commandLine "./build/distributions/$project.name-$version/bin/$project.name".split()
}
