Thanks Adam. I will give it a shot. I thought of using *protoc* compiler,
but what if my proto file contains nested messages
*message A { B b = 1}*
*message B {*
*}*
After running *protoc *on the proto file, it will generate 2 java classes.
I won't know which generated class to use against my .pb file, as my plugin
is only aware of .pb and .proto file.
Please correct me, if am wrong.
