Error executing mapping_engine/main/main.go

[agonzalez-cloud39]

Hello.
When I am trying to execute the main.go file in mapping_engine/main/main.go I am receiving an error . The error is the following:

go: finding github.com/GoogleCloudPlatform/healthcare-data-harmonization latest

Please try running build_all.sh from the root directory.

That should generate the go code from the protos.

Hello, I was able to execute the build_all.sh with this result:

Then, when I ran the mapping_engine/main/main.go I received

go: finding github.com/GoogleCloudPlatform/healthcare-data-harmonization latest
build command-line-arguments: cannot load github.com/GoogleCloudPlatform/healthcare-data-harmonization/mapping_language/parser: module github.com/GoogleCloudPlatform/healthcare-data-harmonization/mapping_language@latest found (v0.0.0-20200825174619-10aeb28a0c45, replaced by /mnt/c/ignw_repo/healthcare-data-harmonization-master/healthcare-data-harmonization-master/mapping_language), but does not contain package github.com/GoogleCloudPlatform/healthcare-data-harmonization/mapping_language/parser

I have installed:
go1.13.9 linux/amd64
libprotoc 3.11.4

Thanks in advance

Please install a Java JRE (8 or 9) and make sure that it's in your PATH. This is required for ANTLR to generate code from the grammar.

We'll be adding a prerequisites section to the Readme to help with this.

@agonzalez-cloud39 Have you tried the Jupyter notebooks environment we provide? It might be easier since the runtime will be built for you.
