third_party/protobuf/3.6.1/examples/BUILD

# This BUILD file shows how to use protobuf with bazel. Before you can use
# proto_library/<lang>_proto_library rules in a BUILD file, you need to
# include protobuf repo as remote repositories in your WORKSPACE file. See
# the WORKSPACE file in the same directory with this BUILD file for an
# example.

# For each .proto file, a proto_library target should be defined. This target
# is not bound to any particular language. Instead, it defines the dependency
# graph of the .proto files (i.e., proto imports) and serves as the provider
# of .proto source files to the protocol compiler.

# Remote repository "com_google_protobuf" must be defined to use this rule.

# Java lite API is a subset of the regular Java API so if you only uses this
# subset in your code, you can actually compile your code against both (i.e.,
# share code between server build and Android build).
#
# The lite version has a smaller code size, and you can see that by comparing
# the resulted .jar file:
#
#   $ bazel build :add_person_java_deploy.jar :add_person_java_lite_deploy.jar
#   $ ls -l bazel-bin/*_deploy.jar
#   -r-xr-xr-x 1 xiaofeng eng 1230797 Sep  8 12:24 bazel-bin/add_person_java_deploy.jar
#   -r-xr-xr-x 1 xiaofeng eng  236166 Sep  8 12:24 bazel-bin/add_person_java_lite_deploy.jar
#
# In the above example, the lite .jar file is 6 times smaller. With proper
# proguard inlining/stripping, the difference can be much more larger than
# that.
