“cannot find symbol method setBatchPath(String)” in the generated source from generated endpoint

Question

For an unknown reason, when I tried to build my Google App Engine endpoints, I get these errors in all of the API java files generated by Android Studio:

Err

Answer 1

Same thing happened to me this morning.

I resolved it by adding this in my backend project

appengine {
    endpoints {
        googleClientVersion = '1.23.0'
    }
}

and updating this version in my app gradle file.

implementation('com.google.api-client:google-api-client-android:1.23.0')

Answer 2

Faced the same problem. I upgraded google client libs to 1.23.0 and it worked (earlier was 1.22.0)

compile 'com.google.api-client:google-api-client:1.23.0'
compile 'com.google.http-client:google-http-client-android:1.23.0'

Answer 3

We already had these in our backend build.gradle:

dependencies {
    compile 'com.google.api-client:google-api-client:+'
    compile 'com.google.api-client:google-api-client-android:+'
    compile 'com.google.http-client:google-http-client:+'
    compile 'com.google.http-client:google-http-client-android:+'
}

All we needed was adding:

appengine {
    endpoints {
        googleClientVersion = '1.23.0'
    }
}

But it'd have been nice if Google didn't break our codes every once in awhile out of the blue and wasting hours of development time!
