+BitBake 'Fetch' implementation for AWS Codeartifact asset.
+
+Class to fetch AWS Codeartifact asset with the AWS cli.
+The aws tool must be correctly installed and configured prior to use.
+
+  SRC_URI = "codeartifact://<domain-owner>@<domain>/<repository>/<namespace>/<package>/<package-version>/<asset>;format=<format>;unpack=0"
+
+The package path should use '/' instead of '.'.
+The format of the package is a required URL parameter.
+Refer to https://docs.aws.amazon.com/codeartifact/latest/ug/download-assets.html.
+
+For example:
+
+  SRC_URI = "codeartifact://111122223333@my_domain/my_repo/com/google/guava/guava/27.1-jre/guava-27.1-jre.jar;format=maven;unpack=0"
+
+    domain-owner:       111122223333
+    domain:             my_domain
+    repository:         my_repo
+    namespace:          com.google.guava
+    package:            guava
+    package-version:    27.1-jre
+    asset:              guava-27.1-jre.jar
+    format:             maven
