5 # This file is meant to be included into a target to provide a rule
6 # to invoke protoc in a consistent manner. This is only to be included
7 # for Java targets. When including this file, a .jar-file will be generated.
8 # For other targets, see protoc.gypi.
10 # To use this, create a gyp target with the following form:
12 # 'target_name': 'my_proto_lib',
20 # 'includes': ['path/to/this/gypi/file'],
23 # The 'proto_in_dir' variable must be the relative path to the
24 # directory containing the .proto files. If left out, it defaults to '.'.
26 # The 'output_java_files' variable specifies a list of output files that will
27 # be generated. It is based on the package and java_outer_classname fields in
28 # the proto. All the values must be prefixed with >(java_out_dir), since that
29 # is the root directory of all the output.
31 # Implementation notes:
32 # A target_name of foo and proto-specified 'package' java.package.path produces:
33 # <(PRODUCT_DIR)/java_proto/foo/{java/package/path/}{Foo,Bar}.java
34 # where Foo and Bar are taken from 'java_outer_classname' of the protos.
36 # How the .jar-file is created is different than how protoc is used for other
37 # targets, and as such, this lives in its own file.
