Jeffrey Alexander created MNG-5852:
--------------------------------------
Summary: "mvn" script invokes /bin/sh but requires /bin/bash
functions
Key: MNG-5852
URL: https://issues.apache.org/jira/browse/MNG-5852
Project: Maven
Issue Type: Bug
Components: Command Line
Affects Versions: 3.3.3
Environment: Solaris 11
Reporter: Jeffrey Alexander
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.
