native-maven-plugin suggested patch to avoid redundant relink

[sintetik]

I've been asking a question some time ago about redundant relink in
native-maven-plugin:
http://maven.40175.n5.nabble.com/c-native-maven-plugin-redundant-linking-at-second-run-problem-td3403291.html

Finally we've started actually using native-maven-plugin so I've patched the
plugin to avoid relink in case of no changes.

We have some other modifications as well but we don't want to fork too much
from publicly available source so I'd like to send to upstream as much as
possible.

Please consider the patch 
http://maven.40175.n5.nabble.com/file/n5075095/maven-native-api.patch
maven-native-api.patch 
http://maven.40175.n5.nabble.com/file/n5075095/native-maven-plugin.patch
native-maven-plugin.patch

Assembly plugin redundant pack / no stale check

[sintetik]

Hi,

I see some kind of unwanted behavior in my project using assembly plugin. It
does the repack all the time, even if no changes have been done. Is there
any way to enforce assembly plugin to enable stale checks? 

Regards,
Sergey.

Re: c++ native-maven-plugin redundant linking at second run problem

[sintetik]

Thank you Mark,

> compilation and linking. 

I guess it means linking will be repeated anyhow even if code didn't change?

I had a thought that it's theoretically possible to resolve my problem
(redundant linking) by creating 2 projects (for every cpp module), one of
them doing compilation and producing obj files and second one just depending
on the first one and performing linking.

This looks somehow ugly though, so I'm thinking about possibility to
"virtualize" this process inside the plugin itself.

Please let me know whether you think if it's possible or any other
considerations.

Thanks,
Sergey.

Thank you, Dan.

What about NAR plugin - does this issue exist in there? I didn't won't to
use NAR first because of its complexity but unfortunately this issue (build
time) is critical for me so I'd consider NAR if it may help.

Sergey.

c++ native-maven-plugin redundant linking at second run problem

[sintetik]

Hi,

I'm trying to migrate my cpp project to native-maven-plugin.
I've got buld succefull but there's a problem with repatable build. The
problem is that both compilation and linking is repeated even is there was
no changes in source code.
All in all, i have total time for the first build (single module) 27 seconds
and next build (same module, no changes) 22 seconds. Looks a bit weird.

Is there any workaround for this?
If not, is there any principal obstacle for patching native-maven-plugin to
fix this?

Regards,
Sergey.
