Summary: Maven fails to load jansi library when /tmp is set to
"noexec"
Key: MNG-7500
URL: https://issues.apache.org/jira/browse/MNG-7500
Project: Maven
Issue Type: Bug
Affects Versions: 3.8.6
Environment: fs@c7cbagent01 :~$ uname -a
Linux c7cbagent01 3.10.0-1160.62.1.el7.x86_64 #1 SMP Tue Apr 5 16:57:59 UTC

Reporter: Reid Madsen
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:
{code:java}
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

Filesystem config for /tmp:
{code:java}
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 {code}
So, as per instructions in error message, I tried:
{code:java}
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>{code}
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.
