The `olca.proto` file contains the definition of the openLCA\nschema format and is generated via the `osch` tool of the [olca-schema project](\nhttps://github.com/GreenDelta/olca-schema).\n\nTo generate the Java source code, we use the\n[protobuf-maven-plugin](https://github.com/xolstice/protobuf-maven-plugin):\n\n```bash\nmvn compile\n```\n\nYou need to have the `protoc` compiler with the gRPC plugin for Java installed.\nOne way to install it, is to just put the binaries of these tools into your\nsystem path. The `protoc` binary can be downloaded from its GitHub release page:\nhttps://github.com/protocolbuffers/protobuf/releases. The gRPC Java plugin\ncan be downloaded from the Maven Central Repository:\nhttps://repo1.maven.org/maven2/io/grpc/protoc-gen-grpc-java/. You may need to\nrename the plugin to `protoc-gen-grpc-java` and set the executable flags:\n\n```bash\nchmod +x protoc-gen-grpc-java\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgreendelta%2Folca-proto","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgreendelta%2Folca-proto","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgreendelta%2Folca-proto/lists"}
