Is there a special install order for packages and z3c.jbot?

Plone Support Add-on Development
1

I have a local installation of Plone 6 classic via pip. If i checkout plone.app.contenttypes to source via mx.ini, then the overrides of some templates via z3c.jbot are broken (means: they are gone) and i see the original templates.

# mx.ini
[settings]
requirements-in = requirements-local.txt
requirements-out = requirements-local-mxdev.txt
contraints-out = constraints-local-mxdev.txt

# if i enable this, then the template overrideing doesn't work

# [plone.app.contenttypes]
# url = https://github.com/plone/plone.app.contenttypes.git
# branch=3.0.2

# requirements-local.txt
-c constraints.txt # points to -c https://dist.plone.org/release/6.0.4/constraints.txt
Plone
plone.app.upgrade
cookiecutter

# install local dev packages
-e ../project/my.theme

<!-- configure.zcml in my.theme -->
<include
    package="z3c.jbot"
    file="meta.zcml"
    />

<browser:jbot
    directory="overrides"
    layer="my.theme.interfaces.IMyThemeLayer"
    />

Has anyone a hint for the direction of debugging?

Not sure, but maybe you can debug in z3c.jbot/manager.py at master · zopefoundation/z3c.jbot · GitHub

z3c.jbot uses some mechanism to detect where the files are located. based on sys.path. With pip editable installs it is possible it has some special needs not covered yet.

This has just happened to me in a project, and I have found out that it is because my packages has no src layout, I mean, the code is directly in the folder instead of in a src folder.

It looks like pip doesn't understand that correctly, because I see that mxdev is creating the requirements-mxdev.txt file correctly.
