無法在Windows上安裝protoc

Question

我正在發現構建protoc jar的問題，它是用於從proto文件生成java類文件的。我真的很感謝任何一種方向或幫助建立項目的水平，我可以從.proto文件生成Java類文件

我從protobuf git repo導入了以下項目，但一直無法找到項目目錄中的protoc.exe文件。

自己抱怨不能夠引用某些類的項目。

當我試圖編譯和使用Maven構建的protobuf-父項目，我得到的錯誤，如下面顯示

，我建議你在Windows上使用預編譯protoc.exe二進制文件。 Download protoc-x.x.x-win32.zip and protoc-x.x.x-java.zip packages

解壓縮文件，你應該得到這樣的文件夾（僅列出一些關鍵文件）：

C:\projects\protoc\protoc-x.x.x-win32\bin\protoc.exe 
C:\projects\protoc\protoc-x.x.x\protobuf.pc.in 
C:\projects\protoc\protoc-x.x.x\java\pom.xml 
C:\projects\protoc\protoc-x.x.x\java\core\* 
C:\projects\protoc\protoc-x.x.x\java\util\* 

使用Maven編譯Java項目，請參閱本幫助蝙蝠腳本：

cd C:\projects\protoc\protobuf-x.x.x\java 
set JAVA_HOME=c:\program files\Java\jdk1.7.0_75 
"c:\apps\apache-maven\bin\mvn.cmd" "-Dprotobuf.source.dir=C:\projects\protoc\protoc-x.x.x-win32\bin" package 

你應該在以下文件夾中查找jar文件，這些文件是在使用MyStructureProto.java或其他protobuf對象（字節對象，對象到字節）時嵌入到項目中的文件。

C:\projects\protoc\protoc-x.x.x\java\core\target\protobuf-java-3.3.0.jar 
C:\projects\protoc\protoc-x.x.x\java\util\target\protobuf-java-util-3.3.0.jar 

使用protoc.exe從.proto模板描述創建Java實現：

C:\projects\protoc\protoc-x.x.x-win32\bin\protoc.exe --java_out=. MyStructureProto.proto
