[yocto] do_populate_lic fail from scratch build but succed after clean

[Jonas Andersson]

Hi

I have an recipe based on serialport npm package created with devtool.

I added some custom licenses in my layer with LICENSE_PATH:

# Additional license directories.
LICENSE_PATH += "${LAYERDIR}/files/common-licenses"

After this I get some inconsistent build result (or i dont understand ).

Te steps I make is the following, build from scratch then bitbake fails,
clean recipe and build recipe and it succed:

1. bitbake myLayer ->

WARNING: serialport-6.2.2-r0 do_populate_lic: Could not copy license file

to

.

task.
ERROR: serialport-6.2.2-r0 do_populate_lic: Function failed:
populate_lic_qa_checksum

2. bitbake serialport -c clean
3. bitbake serialport -> success

In my view it feels like different tasks is executed in different order,
like the npm recipe is missing some dependency but before I adden
LICENSE_PATH to the layer config I had no problem..
