mbed deploy cannot handle changing URI for .lib-files

[JanneKiiskila]

See demonstrator and reproduction steps in mbed-cli-mbed-deploy-issue.

A simple repo to demostrate bug in mbed deploy. It does not handle correctly an update in the .lib -URI path change, i.e. if you switch to a different fork of the repo for example.

Reproduction steps

Install the normal cli tooling following the official Mbed OS documentation.
Personally, I highly recommend using a Python virtualenv for this.

Check installation.

mbed --version
1.10.5

Start by mbed import with this repo.

mbed import [email protected]:JanneKiiskila/mbed-cli-mbed-deploy-issue.git
cd mbed-cli-mbed-deploy-issue/

This will also do the mbed deploy automatically.

Now, check into the branch fork. This would pick up a different URI for the wifi-ism43362 repo.

git checkout fork
mbed deploy

The deploy will fail.

~/mbed/mbed-cli-mbed-deploy-issue$ mbed deploy
[mbed] Working path "/home/jannek/mbed/mbed-cli-mbed-deploy-issue" (library)
[mbed] Program path "/home/jannek/mbed/mbed-cli-mbed-deploy-issue"
[mbed] Updating library "wifi-ism43362" to rev #6e2e009be907
fatal: reference is not a tree: 6e2e009be907215bd2fa41df7ca1a18e10ab6b0a
[mbed] ERROR: Unable to update "wifi-ism43362" to rev #6e2e009be907
---

This is due to the fact, that the wifi-ism43362 git remote is still pointing to the
original one, which of course does not have the same hashes as the fork.

~/mbed/mbed-cli-mbed-deploy-issue/cd wifi-ism43362
~/mbed/mbed-cli-mbed-deploy-issue/wifi-ism43362$ git remote -v
origin	https://github.com/ARMmbed/wifi-ism43362 (fetch)
origin	https://github.com/ARMmbed/wifi-ism43362 (push)

Workaround

You are required to manually delete the deployed repo/folder and then doing mbed deploy again.

rm -rf wifi-ism43362
mbed deploy

This will work, as it will start with a clean git clone operation with the correct repo URI.

However, this is a fully manual process. The tool could alternatively also notice the URI change and just add a different remote (or change the remote).
