Install and Create output

Warning

This is an experimental feature subject to breaking changes in future releases.

The conan install and conan create provide a --json parameter to generate a file containing the information of the installation process.

The output JSON contains a two first level keys:

• error: True if the install completed without error, False otherwise.

• installed: A list of installed packages. Each element contains:

  • recipe: Document representing the downloaded recipe.

    • remote: remote URL if the recipe has been downloaded. null otherwise.

    • cache: true/false. Retrieved from cache (not downloaded).

    • downloaded: true/false. Downloaded from a remote (not in cache).

    • time: ISO 8601 string with the time the recipe was downloaded/retrieved.

    • error: true/false.

    • id: Reference. E.g., “openssl/1.0.2u”

    • name: name of the packaged library. E.g., “openssl”

    • version: version of the packaged library. E.g., “1.0.2u”

    • user: user of the packaged library. E.g., “conan”

    • channel: channel of the packaged library. E.g., “stable”

    • dependency: true/false. Is the package being installed/created or a dependency. Same as develop conanfile attribute.

  • packages: List of elements, representing the binary packages downloaded for the recipe. Normally there will be only 1 element in this list, only in special cases with build requires, private dependencies and settings overridden this list could have more than one element.

    • remote: remote URL if the recipe has been downloaded. null otherwise.

    • cache: true/false. Retrieved from cache (not downloaded).

    • downloaded: true/false. Downloaded from a remote (not in cache).

    • time: ISO 8601 string with the time the recipe was downloaded/retrieved.

    • error: true/false.

    • id: Package ID. E.g., “8018a4df6e7d2b4630a814fa40c81b85b9182d2b”

    • cpp_info: dictionary containing the build information defined in the package_info method on the recipe.

Example:

$ conan install openssl/1.0.2u@ --json install.json

install.json

As this is a marked as experimental, some fields may be removed or added: fields version and description inside cpp_info will eventually be removed and paths may be changed for absolute ones.
