Environment Details (include every applicable attribute)

  • Operating System+version: untu:20.04 (docker), python:windowsservercore-1809 (docker), Windows 10 20H2
  • Compiler+version: gcc 9, Visual Studio 16
  • Conan version: 1.43
  • Python version: 3.9.9

Steps to reproduce (Include if Applicable)

$ conan new mylib/0.1 --template=cmake_lib

then edit conanfile.py to use CMakeDeps generator and requires "poco/1.9.4"

from conans import ConanFile
from conan.tools.cmake import CMake
from conan.tools.layout import cmake_layout

class MylibConan(ConanFile):
    name = "mylib"
    version = "0.1"

    # Optional metadata
    license = "<Put the package license here>"
    author = "<Put your name here> <And your email here>"
    url = "<Package recipe repository url here, for issues about the package>"
    description = "<Description of Mylib here>"
    topics = ("<Put some tag here>", "<here>", "<and here>")

    # Binary configuration
    settings = "os", "compiler", "build_type", "arch"
    options = {"shared": [True, False], "fPIC": [True, False]}
    default_options = {"shared": False, "fPIC": True}

    requires = "poco/1.9.4"
    generators= "CMakeToolchain", "CMakeDeps"

    # Sources are located in the same place as this recipe, copy them to the recipe
    exports_sources = "CMakeLists.txt", "src/*"

    def config_options(self):
        if self.settings.os == "Windows":
            del self.options.fPIC

    def layout(self):
        cmake_layout(self)

    def build(self):
        cmake = CMake(self)
        cmake.configure()
       cmake.build()

    def package(self):
        cmake = CMake(self)
        cmake.install()

    def package_info(self):
        self.cpp_info.libs = ["mylib"]

When calling
$ conan create . demo/testing -pr:b=default
sometimes everything is ok, sometimes I get this error:
ERROR: Error in generator 'CMakeDeps': Component 'poco::poco_crypto' not found in 'poco' package requirement

If I call again $ conan create . demo/testing -pr:b=default after the error, same result: sometimes ok, sometimes not.

Logs (Executed commands with output) (Include/Attach if Applicable)

No Error log

This seems a result of the latest changes in 1.43, because the recipes have not been upgraded to fix the properties in ConanCenter. As soon as the PRs gets merged in ConanCenter, this will work again.

This issue appears with conan 1.42.1 too

Well, some of the properties have already started to be merged in ConanCenter (those will not work in 1.42.1 either), so at the moment it is in a transition state where some packages will only work in 1.43 and others in 1.42 (even ones in the same dependency graph), until the different recipes being involved all migrate to the new properties, it will be a bit unstable.

Ok I understand but here, one second it works, the next one it doesn't. Can the property explain this ?
I can execute a loop of conan create command and ~50% will failed

No, that is really weird. Unless there is some CDN propagation thing or something, and it is being resolved to different locations... you are right, if that is the behavior, it is worth having a look (for me it fails consistently)

Yes, that's weird. I'm trying to figure out what's going on. In my case, it's failing randomly in macOS.

I guess I know what's happening. Look at the following pieces of log.

If you realize, all the generators are being randomly executed so I think that's what is causing the error.

I don't think the order of generators would change much, but maybe something to look is the order of dependencies inside the CMakeDeps, which might influence the order in which transitive dependencies are evaluated. I suggest printing it and checking.

In the meantime, how can I avoid this issue? Any workaround ? How to manage package dependencies without CMakeDeps ?

I managed to see what was happening. I am going to submit a patch asap to be included in 1.43.1 which will also be released asap
