Description

All of our CICD build servers (CentOS 7) are configured with /tmp being set to 'noexec'.  In that environment when I run maven (v3.8.6) I get the following error:

fs@c7cbagent01 :~$ mvn --version
Failed to load native library:jansi-2.4.0-14d515591f448fb6-libjansi.so. The native library file at /tmp/jansi-2.4.0-14d515591f448fb6-libjansi.so is not executable, make sure that the directory is mounted on a partition without the noexec flag, or set the jansi.tmpdir system property to point to a proper location.  osinfo: Linux/x86_64

fs@c7cbagent01 :~$ cat /etc/redhat-release 
CentOS Linux release 7.9.2009 (Core)

Filesystem config for /tmp:

fs@c7cbagent01 :~$ cat /etc/fstab | grep tmp
/dev/mapper/rootvg-tmplv /tmp                    xfs     nodev,nosuid,noexec 0 0
/tmp            /var/tmp        none    bind        0 0
tmpfs            /dev/shm        tmpfs    nodev,nosuid,noexec        0 0 

So, as per instructions in error message, I tried:

fs@c7cbagent01 :~$ mkdir ~/tmp
fs@c7cbagent01 :~$ chmod 777 ~/tmp

fs@c7cbagent01 :~$ mvn -Djansi.tmpdir=~/tmp --version
<SAME ERROR AS ABOVE>

fs@c7cbagent01 :~$ mvn -Djansi.tmpdir=~/tmp -Djava.io.tmpdir=~/tmp--version
<SAME ERROR AS ABOVE>

fs@c7cbagent01 :~$ export TMPDIR=~/tmp
fs@c7cbagent01 :~$ mvn -Djansi.tmpdir=~/tmp -Djava.io.tmpdir=~/tmp--version
<SAME ERROR AS ABOVE>

So, pray tell, what do I need to do to work around this issue.

It also appears that setting /tmp as 'noexec' is a common security feature.  Perhaps maven should establish a location outside of /tmp for the extraction of these libraries.
