We build and test two third party parsers, Hive and Calcite, and wrap these two parsers into either a gRPC server or a command line.

To make sure that all developers use the same version and configuration of development tools like JDK and Maven, we install all of them into a Docker image sqlflow/sqlflow:ci.

To download the image, type the following command

docker pull sqlflow/sqlflow:ci

To start a Docker container that runs the above image, we can type the following command:

docker run --rm -it -v $HOME:/root -v $PWD:/work -w /work sqlflow/sqlflow:ci bash

Please be aware the -v $HOME:/root binds the $HOME directory on the host to the /root, the home directory, in the container, so that when we run Maven in the container, it saves the downloaded jars into $HOME/.m2.

In the container, we can type the following command to generate the gRPC related code.

protoc --java_out=src/main/java --grpc-java_out=src/main/java/ --proto_path=src/main/proto/ src/main/proto/parser.proto

In the container, we can type the following command to test the package

mvn test
