question regarding updating submodules of cam

[mvertens]

I am trying to udpate a submodule of cam (in my case oslo_aero) to my own branch

I have tried the following:

> git clone https://github.com/NorESMhub/NorESM noresm3_0_beta03
> cd noresm3_0_beta03
> git checkout noresm3_0_beta03
> ./bin/git-fleximod update

in components/cam/.gitmodules I make the following change from

 [submodule "oslo_aero"]
     path = src/chemistry/oslo_aero
     url = https://github.com/NorESMhub/OSLO_AERO
     fxtag = oslo_aero_3_0a007
     fxrequired = AlwaysRequired
     fxDONOTUSEurl = https://github.com/NorESMhub/OSLO_AERO.git

to

[submodule "oslo_aero"]
    path = src/chemistry/oslo_aero
    url = https://github.com/mvertens/OSLO_AERO
    fxtag = 2218bd9
    fxrequired = AlwaysRequired
    fxDONOTUSEurl = https://github.com/NorESMhub/OSLO_AERO.git

And I tried the following test1:

> cd components/cam
>  ./bin/git-fleximod update oslo_aero

No submodule components found, root_dir=/cluster/projects/nn10013k/mvertens/src/noresm3_0_beta03

then test2:

Test2 seems to work - but why did test1 not work?

git-fleximod is processing submodules with respect to the top level directory (noresm3_0_beta03), but you are referencing the
cam submodule with respect to the components/cam subdirectory. So after you modify the .gitmodules file in components/cam if you run
git-fleximod update cam
It will complete the expected action.

@jedwards4b - thanks for the explanation.
