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 the next section.

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 - 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.
