Protocol Buffers - Google's data interchange format
|
||
|
|
Copyright 2008 Google Inc.
|
||
|
|
|
||
|
|
This directory contains the Java Protocol Buffers runtime library.
|
||
|
|
|
||
|
|
Installation - With Maven
|
||
|
|
=========================
|
||
|
|
|
||
|
|
The Protocol Buffers build is managed using Maven. If you would
|
||
|
|
rather build without Maven, see below.
|
||
|
|
|
||
|
|
1) Install Apache Maven if you don't have it:
|
||
|
|
|
||
|
|
http://maven.apache.org/
|
||
|
|
|
||
|
|
2) Build the C++ code, or obtain a binary distribution of protoc. If
|
||
|
|
you install a binary distribution, make sure that it is the same
|
||
|
|
version as this package. If in doubt, run:
|
||
|
|
|
||
|
|
$ protoc --version
|
||
|
|
|
||
|
|
You will need to place the protoc executable in ../src. (If you
|
||
|
|
built it yourself, it should already be there.)
|
||
|
|
|
||
|
|
3) Run the tests:
|
||
|
|
|
||
|
|
$ mvn test
|
||
|
|
|
||
|
|
If some tests fail, this library may not work correctly on your
|
||
|
|
system. Continue at your own risk.
|
||
|
|
|
||
|
|
4) Install the library into your Maven repository:
|
||
|
|
|
||
|
|
$ mvn install
|
||
|
|
|
||
|
|
5) If you do not use Maven to manage your own build, you can build a
|
||
|
|
.jar file to use:
|
||
|
|
|
||
|
|
$ mvn package
|
||
|
|
|
||
|
|
The .jar will be placed in the "target" directory.
|
||
|
|
|
||
|
|
Installation - 'Lite' Version - With Maven
|
||
|
|
==========================================
|
||
|
|
|
||
|
|
Building the 'lite' version of the Java Protocol Buffers library is
|
||
|
|
the same as building the full version, except that all commands are
|
||
|
|
run using the 'lite' profile. (see
|
||
|
|
http://maven.apache.org/guides/introduction/introduction-to-profiles.html)
|
||
|
|
|
||
|
|
E.g. to install the lite version of the jar, you would run:
|
||
|
|
|
||
|
|
$ mvn install -P lite
|
||
|
|
|
||
|
|
The resulting artifact has the 'lite' classifier. To reference it
|
||
|
|
for dependency resolution, you would specify it as:
|
||
|
|
|
||
|
|
<dependency>
|
||
|
|
<groupId>com.google.protobuf</groupId>
|
||
|
|
<artifactId>protobuf-java</artifactId>
|
||
|
|
<version>${version}</version>
|
||
|
|
<classifier>lite</classifier>
|
||
|
|
</dependency>
|
||
|
|
|
||
|
|
Installation - Without Maven
|
||
|
|
============================
|
||
|
|
|
||
|
|
If you would rather not install Maven to build the library, you may
|
||
|
|
follow these instructions instead. Note that these instructions skip
|
||
|
|
running unit tests.
|
||
|
|
|
||
|
|
1) Build the C++ code, or obtain a binary distribution of protoc. If
|
||
|
|
you install a binary distribution, make sure that it is the same
|
||
|
|
version as this package. If in doubt, run:
|
||
|
|
|
||
|
|
$ protoc --version
|
||
|
|
|
||
|
|
If you built the C++ code without installing, the compiler binary
|
||
|
|
should be located in ../src.
|
||
|
|
|
||
|
|
2) Invoke protoc to build DescriptorProtos.java:
|
||
|
|
|
||
|
|
$ protoc --java_out=src/main/java -I../src \
|
||
|
|
../src/google/protobuf/descriptor.proto
|
||
|
|
|
||
|
|
3) Compile the code in src/main/java using whatever means you prefer.
|
||
|
|
|
||
|
|
4) Install the classes wherever you prefer.
