Michael Osipov commented on MNG-6115:
-------------------------------------
[~hboutemy], all the hard work is done by HawtJNI, see
[here|https://github.com/fusesource/hawtjni/blob/master/hawtjni-runtime/src/main/java/org/fusesource/hawtjni/runtime/Library.java].
[~rfscholte], this won't work. See
[here|https://github.com/fusesource/hawtjni/blob/master/hawtjni-runtime/src/main/java/org/fusesource/hawtjni/runtime/Library.java#L175-L185].
OS and arch are only evaluated if the library it is extracted from the JAR.
Unless someone changes HawtJNI to our needs, this won't scale. I would ship a
modified JAR without {{jansi-1.13.jar!/META-INF/native}} (or rename) to avoid
the constant extraction, add the patch Hervé did and add documentation for
users if they need {{istty}} support, they have to place
{{libjansi.so}}/{{libjansi.dylib}}/{{jansi.dll}} to {{$\{maven.home}/lib/ext}}.
Personally, I would people expect to put the library to {{/usr/local/lib}}
once. This is where a native lib belongs and modify {{library.jansi.path}}.
This is what I will recommend for the FreeBSD port of Maven. Alternatively, the
user can always set {{LD_LIBRARY_PATH}} in his {{mavenrc}} pointing to the
directory where the native lib resides.
There is a reason why I have created this ticket months ago.
> Add Jansi native library search path to our start scripts

> Key: MNG-6115
> URL: https://issues.apache.org/jira/browse/MNG-6115
> Project: Maven
> Issue Type: Improvement
> Components: Bootstrap & Build, Command Line
> Reporter: Michael Osipov
> Assignee: Hervé Boutemy
> Fix For: 3.5.0-alpha-2
>
>
> By default Jansi extracts the native, shared library to temp which results in
> unnecessary file I/O and a huge amount of temp files when Maven is run very
> often. One can avoid that by adding
> {{-Dlibrary.jansi.path=$\{MAVEN_HOME\}/lib/ext}} to the start script. The
> user has to copy the {{libjansi.so}} or {{jansi.dll}} once and will avoid the
> overhead.
