> The bin/mvn script uses the "local" command which is a shell builtin of bash and similar shells, but is not required for POSIX-compliance in sh.  When I attempt to run mvn on my Solaris system, I see the following output:
> $ ./mvn
> ./mvn[200]: local: not found [No such file or directory]
> ./mvn[201]: local: not found [No such file or directory]
> ...
> Lines 200 and 201 invoke "local" to make local variables to the function.  According to "man bash", this is a shell builtin.  However, bin/mvn is invoked as:
> #!/bin/sh
> On most flavors of linux, this resolves to bash or dash which probably runs in a restricted environment after checking to see that its $0 is sh. But on Solaris's /bin/sh is actually ksh93 for backwards compatibility.
> Since "local" is not part of a POSIX-compliant /bin/sh, depending on it in a script that is invoked with /bin/sh is a bug.
