"package io.grpc does not exist" and "static import only from classes and interfaces" when trying to generate Java Protobuf code
I'm trying to follow along this blog post, https://redbyte.eu/en/blog/calling-java-from-go-using-grpc/, in this repository, https://github.com/khpeek/pdf-parser. After running ./gradlew build, the project has the following structure:
.

The issue is that ./gradlew build returns the following errors:

I've tried adding the following line to the dependencies in the build.gradle,
compile group: 'io.grpc', name: 'protoc-gen-grpc-java', version: '1.14.0'
but this led to the same error. Any ideas how to fix the Gradle build?

io.grpc.* is in grpc-api (which most other grpc dependencies will depend on). io.grpc.stub.* is in grpc-stub. io.grpc.protobuf.* is in grpc-protobuf. javax.annotation.Generated can be found in Tomcat's annotations-api.
So you need to add (as mentioned in the grpc-java readme):
implementation "io.grpc:grpc-protobuf:1.14.0"
implementation "io.grpc:grpc-stub:1.14.0"
compileOnly "org.apache.tomcat:annotations-api:6.0.53"
gRPC v1.14.0 is quite old; you should upgrade to a newer version for actual use. To actually run, you probably need implementation 'io.grpc:grpc-netty-shaded:1.34.1' as well.
