Matt Foley commented on HADOOP-8924:
------------------------------------
How about the following:
1. convert saveVersion.sh into saveVersion.java. Pass the parameter values
(including the root of the source tree for checksum calculation) in to the
class constructor at invocation time.
2. add a dependency rule that causes saveVersion.class to be compiled before
any other java is compiled, and separately from it.
3. add a simple execution outcall from ant or maven that calls the class, and
passes the parameter values in to the call. If maven requires a completely
vanilla "plug-in" to do this well, I'm okay with that. I just don't want the
significant functionality of saveVersion.java to be subsumed into the plug-in
and become opaque to the hadoop source.

> Currently, the build process relies on saveVersion.sh to generate
> package-info.java with a version annotation. The sh binary may not be
> available on all developers' machines (e.g. Windows without Cygwin). This
> issue tracks removal of that dependency in Hadoop Common.
