Jonathan Dowland created MNG-7270:
-------------------------------------
Summary: maven shell script wrapper (init) calls "which", which
might not be installed
Key: MNG-7270
URL: https://issues.apache.org/jira/browse/MNG-7270
Project: Maven
Issue Type: Bug
Components: Command Line
Affects Versions: 3.8.2
Environment: UNIX/POSIX, Linux
Reporter: Jonathan Dowland
The "init" shell wrapper script, that often ends up as /usr/bin/mvn in
downstream distributions, calls the program "which" in the situation where
JAVA_HOME is not defined.
"which" is a separate binary program that may or may not be installed.
Increasingly it may not be in environments which are trying to reduce their
install footprint e.g. containers.
A portable alternative is to use `command -v` with some defensive commands
prior (unalias, unset: see
[https://pubs.opengroup.org/onlinepubs/009695399/utilities/command.html).]--
I've got a PR ready to go.
