Thank you, Steve. If I make the executable="/bin/sh" and uncomment the
protoc command, I get:
parsing buildfile
jar:file:/usr/apache-ant-1.9.4/lib/ant.jar!/org/apache/tools/ant/antlib.xml
with URI =
jar:file:/usr/apache-ant-1.9.4/lib/ant.jar!/org/apache/tools/ant/antlib.xml
from a zip file
[mkdir] Skipping /root/CCM/srcProtobufJava because it already exists.
[chmod] Executing 'chmod' with arguments:

[chmod] not part of the command.

[exec] Result: 126
Thoughts?

Wild cards like /root/CCM/src/protobuf/asf/*.proto are expanded by the
shell in unix type o/s's. When you took out the /bin/sh you no longer
get this expanded. It works when you run it from the command line
because you are giving the command to the shell and it expands the
wildcard for you.
