Simple Plone Buildout (Windows) : no Add-on-eggs picked?

Hello,

I want to migrate my Plone 4 / Windows to Plone 5 / Windows.

To test Add-ons, I installed Simple Plone Buildout / Plone 5.0.8 on a Windows-Test-PC.
But when I added two Add-on-eggs in the original buildout.cfg (Simple Plone Buildout)...:

[buildout]
index = https://pypi.python.org/simple/

extends = profiles/testing.cfg

eggs += products.windowz

[instance]
eggs += ftw.calendar

...only the egg in the [instance]-section (ftw.calendar) was picked, not the egg in the [buildout]-section (products.windowz):

products.windowz and ftw.calendar are Plone 5 compatible. I added them also for testing in testing.cfg, release.cfg, base.cfg, but the behavior was the same: only the egg in the [instance]-section was picked, not the egg in the [buildout]-section.
So what am I doing wrong?

I think you mis-spelled the name (at least if it is this: https://github.com/collective/Products.windowZ )

Maybe 'Capital letters do not matter on Windows.
Also: all the eggs should be added to the same section of buildout.cfg, like here: https://github.com/collective/minimalplone5/blob/master/buildout.cfg

AFAIK case insensitivity depends on Pypi servers, not on the operating system.

modifying profiles/testing.cfg in simple-buildout like this:

[instance]
eggs += 
   colleCtivE.glOSSarY
   cOLLeCtive.AMBIDEXTeritY

produces:

Getting distribution for 'colleCtivE.glOSSarY'.
warning: no previously-included files matching '*.pyc' found anywhere in distribution
Got collective.glossary 1.0b1.
Getting distribution for 'cOLLeCtive.AMBIDEXTeritY'.
warning: no previously-included files matching '*.pyc' found anywhere in distribution
Got collective.ambidexterity 1.0.

forgot to add that was tested under Linux.

The eggs option in the [buildout] section does nothing on its own. Some other section needs to refer to it, otherwise it is ignored.

[buildout
eggs =
    one

[instance]
recipe = some.recipe
eggs =
    ${buildout:eggs}
    two

In this case, both one and two end up in the instance, and you can add extra eggs to either of of the eggs options.

I normally don't use an eggs option in [buildout], but only in the part where it is really used, like [instance]. But there can always be sane reasons to use it anyway.

Thanks to all!

It works:

[instance]
eggs +=
ftw.calendar
products.windowz
