We can add a 'versions' section in buildout.cfg to indicate the version of used recipes.

ie: buildout.cfg for myProject-1.0


[buildout]



parts =

    zope2

    instance



versions = myProject-1.0



[myProject-1.0]

plone.recipe.zope2install = 0.2

plone.recipe.zope2instance = 0.8



[zope2]

recipe = plone.recipe.zope2install

url = http://www.zope.org/Products/Zope/2.9.7/Zope-2.9.7-final.tgz



[instance]

recipe = plone.recipe.zope2instance

zope2-location = ${zope2:location}

user = admin:admin

debug-mode = off

zodb-cache-size = 70000

This way, buildout will use plone.recipe.zope2install version 0.2 and plone.recipe.zope2instance version 0.8. For other stuff like setuptools it will "pick" the best distribution. We can tell buildout to generate an error when it "Picks" a version:


[buildout]



parts =

    zope2

    instance



versions = myProject-1.0

allow-picked-versions = false



[myProject-1.0]

plone.recipe.zope2install = 0.2

plone.recipe.zope2instance = 0.8



[zope2]

recipe = plone.recipe.zope2install

url = http://www.zope.org/Products/Zope/2.9.7/Zope-2.9.7-final.tgz



[instance]

recipe = plone.recipe.zope2instance

zope2-location = ${zope2:location}

user = admin:admin

debug-mode = off

zodb-cache-size = 70000
