Attributes can be used to store information related to the build.\n- *Files* can be added with `setFile()`; the file is tracked and managed by `BuildInfo` during the invocation lifecycle (for example, properly handled during sharding). This avoids the need for the test to know anything about the file system and instead can rely on the abstracted `BuildInfo` object to get their resources.\n\n| **Note:** Files should always be stored in `Files` and not in `Attributes` as an absolute path. Attributes are treated as pure Java strings, and the reference could be invalidated during part of the invocation lifecycle.\n\nBuildInfo in multi-devices\n--------------------------\n\nWhen a test configuration is set up with multiple devices, one `BuildInfo`\nobject exists per device. This allows requesting and targeting files from one\ndevice to another.\n\nBuildInfo in multi-builds\n-------------------------\n\nIt's possible to require builds from several targets. In these cases, one\n`BuildInfo` object exists per target. This allows requesting and targeting\nfiles from any target.\n\nProto format\n------------\n\n`BuildInfo` is serializable in a protobuf format to make its usage easier across\nsystems if needed."]]
