conan_packager

This is an attempt to integrate conan into my TeamCity build system. The top project and all dependencies are built by executing the following steps in TeamCity. Old versions of the top package are cleaned up, the top package and missing dependencies are built and all built packages are uploaded to to my conan server. Lastly the artifacts are deployed and gathered to the TeamCity server.

Step 1: Clean

Perform a cleanup of the local package that we are going to build. The varaibles channel_name and profile_name are set from TeamCity.

from packager import ConanPackager


packager = ConanPackager(channel="%channel_name%", profile="%profile_name%")
packager.remove()

Step 2: Determine pacakges to upload

Obtain a list of packages that will be built. This will be used later when uploading packages.

from cmake import ConanPackager
import os
import json


packages_file = "%package_list%"
packager = ConanPackager(channel="%channel_name%", profile="%profile_name%")

if os.path.isfile(packages_file):
    os.remove(packages_file)

to_upload = packager.determine_packages_to_upload()
with open(packages_file, 'w') as outfile:
    json.dump(to_upload, outfile)

Step 3: Build

Perform a build of the package, including dependencies if necesarry.

from packager import ConanPackager


packager = ConanPackager(channel="%channel_name%", profile="%profile_name%")
packager.create()

Step 4: Upload packages

Upload package and all built dependencies.

from cmake import ConanPackager
import os
import json


packages_file = "%package_list%"
packager = ConanPackager(channel="%channel_name%", profile="%profile_name%")

to_upload = None
with open(packages_file, 'r') as infile:
    to_upload = json.load(infile)

packager.upload_packages(to_upload)

Step 5: Deploy

As the packages are built in the conan data directory, deploy the packages to the build directory for TeamCity to pick up.

from cmake import ConanPackager
import os
import json


metadata_file = "%metadata_file%"
packager = ConanPackager(channel="%channel_name%", profile="%profile_name%")
if os.path.isfile(metadata_file):
    os.remove(metadata_file)

with open(metadata_file, 'w') as outfile:
    json.dump(packager.metadata, outfile)

packager.deploy()
