Gili commented on MNG-6225:
---
Thanks for asking for a minimal testcase. As painful as it was to try to
produce, it helped me figure out the problem.
* In order to use native code, one has to point {{java.library.path}} to the
directory holding the native library.
* There are 3 ways to set this:
** Plugin-specific configuration (e.g. Surefire
{{-Djava.library.path=X}})
** Pass the system properties to the {{mvn}} command-line launcher: {{mvn
-Djava.library.path=X goals}}
** Set {{MAVEN_OPTS=-Djava.library.path=X}} prior to running {{mvn}}
command-line launcher.
I was initially configuring Surefire with {{0}} and
setting {{}}. I assumed that adding {{0}} would
be enough to transition from a forked processed to a non-forked process, but I
was wrong. When the process is not forked, {{}} gets ignored and the
system properties of the initial Maven process gets used instead. This seems
obvious in hindsight but was not obvious at the moment.
I then tried the other two options. It turns out that {{mvn -Dkey=value goals}}
is meant for non-JVM system properties (e.g. if the user application wants to
read a system property). This leaves us with one option: setting the
{{MAVEN_OPTS=-Djava.library.path=X}} environment variable. This worked.
As a result, I would like to request two changes:
1. Maven CLI should warn when it is passed a JVM system property since we know
these cannot be set this way.
2. Surefire should warn when {{0}} is mixed with
{{}}
I will file a separate bug report against Surefire for the second point. Are
you able to convert this bug report for the first point?
