如何编译google-fhir proto文件 [英] How to compile google-fhir proto files

问题描述

查看google-fhir的自述文件，它说要运行 bazel build ，这有效，但是没有编译任何协议文件。

Looking at the readme for google-fhir it says to run bazel build, which works, however none of the protocol files have been compiled.

运行 protoc --proto_path =。 --java_out =。 proto / stu3 / resources.proto 返回一堆关于未找到其他protos的错误。这会向后移动，直到'descriptor.proto'不是文件夹中的原型。该目录中的所有协议文件都不会手动编译成java文件。

Running protoc --proto_path=. --java_out=. proto/stu3/resources.proto returns a bunch of error about other protos not being found. This goes backwards until 'descriptor.proto' which is not a proto in the folder. None of the protocol files in that directory will manually compile into java files.

*另一方面，我能够从其他来源获取其他示例protos并成功编译。

*On another note, I was able to take other example protos from other sources and compile those successfully.

更新

运行命令 protoc - 来自google-fhir基目录的-proto_path = proto / stu3 / --java_out = target proto / stu3 / resources.proto 返回以下输出：

Running the command protoc --proto_path=proto/stu3/ --java_out=target proto/stu3/resources.proto from the google-fhir base directory returns the following output:

~/fhir-master$ protoc --proto_path=proto/stu3/ --java_out=target proto/stu3/resources.proto
proto/stu3/annotations.proto: File not found.
proto/stu3/codes.proto: File not found.
proto/stu3/datatypes.proto: File not found.
resources.proto: Import "proto/stu3/annotations.proto" was not found or had errors.
resources.proto: Import "proto/stu3/codes.proto" was not found or had errors.
resources.proto: Import "proto/stu3/datatypes.proto" was not found or had errors.
resources.proto:84:5: "String" is not defined.
resources.proto:87:14: "Extension" is not defined.
resources.proto:90:14: "Extension" is not defined.
resources.proto:94:5: "Reference" is not defined.
resources.proto:97:5: "PositiveInt" is not defined.
...
...

这些文件肯定位于同一个原型目录中。

Those files are definitely located in the same proto directory.

更新2

嗯，这绝对不是开箱即用的。移动文件，我能够用一堆Java文件生成目标文件夹。但是，尝试编译它们时，我会收到不存在的文件的错误：

Well, this definitely doesn't work right out of the box. Moving the files around, I was able to generate the target folder with a bunch of Java files. However, trying to compile them, I get errors for files that don't exist:

  symbol:   class CodeableConcept
  location: package com.google.fhir.stu3.proto
./PlanDefinition.java:30950: error: cannot find symbol
  public com.google.fhir.stu3.proto.CodeableConceptOrBuilder getJurisdictionOrBuilder(

  100 errors.

！另外，我在这里看不到这些文件： https://github.com/google/protobuf/tree/master/java/core/src/main/java/com/google/protobuf

! Also, I don't see these file here: https://github.com/google/protobuf/tree/master/java/core/src/main/java/com/google/protobuf

推荐答案

看起来你的编译命令格式不正确：
--proto_path =这是proto的路径
--java_out =这是您的类将被编译的文件夹

it looks like your command for compilation is not well formatted: --proto_path= This is the path to your proto --java_out= This is the folder where your class will be compiled

您的论点是：proto / stu3 / resources.proto，因此我推断您的文件位于proto / stu3中。

Your arguement is: proto/stu3/resources.proto, so I deduce that your files are located in proto/stu3.

你可以尝试这个命令，告诉我们它是否适合你：

Could you try this command and let us know if it worked for you:

protoc --proto_path=proto/stu3/ --java_out=target proto/stu3/resources.proto

如果你的proto描述符已经完成，你应该没有编译错误，你的结果应该在target文件夹中。

If your proto descriptor are complete, you should have no compilation error, and your result should be in the folder "target".

编辑：
看在你的最新编辑中，我会说你应该将resources.proto移动到你的基目录并运行以下命令：
protoc --proto_path =。 --java_out = target resources.proto

由于导入的路径已在导入中编码。
这有点难以帮助，因为我们无法访问您的整个proto描述符。如果你从在线回购中获取它，如果你可以分享它会有所帮助。

As the path to your import is coded in your import. This is a bit difficult to help, as we don't have access to your entire proto descriptor. If you took it from an online repo, it would help if you could share it.
