[QGIS-Developer] Deploy plugin by setting QGIS_PLUGINPATH

[Richard Duivenvoorde]

I think what Zhang Qun is asking if he can use a custom directory to
store his plugin in.
If I grep in the source dir of QGIS I see a lot of references to
QGIS_PLUGINPATH, so it should work.
I also see in the changelog that is there since 2010 (and a lot of fixes
for windows environments....)

Do you seen the QGIS_PLUGINPATH in the Options/System tab?

Also does it not show up in the plugin list of the plugin manager?
Because if you install a plugin by copying it to the plugin dir (even
the default one), it is not enabled by default. So IF shown, enable it
in the plugin manager first.

FYI: grepping:

grep -ir QGIS_PLUGINPATH *
