[YANGTOOLS-1428] Missing failedSource in SchemaResolutionException

Relates — Tue, 3 May 2022 20:31:22 +0000

SchemaResolutionException thrown from AssembleSources does not have failedSource even though the information is available in SomeModifiersUnresolvedException wrapped in YangParserException, which in turn included in SchemaResolutionException.

For example, the following two data modules does not compile successfully, as expected, because the target path of the deviation statement is invalid.

orig.yang

module orig {
  namespace "urn:orig";
  prefix orig;

  container foo {
    leaf bar {
      type string;
    }
  }
}

deviate.yang

module deviate {
  namespace "urn:deviate";
  prefix dev;

  import orig {
    prefix orig;
  }

  deviation "/orig:foo/orig:bar/orig:baz" {
    deviate not-supported;
  }
}

When this error occurs during NETCONF mounting process, the whole mounting process fails because NETCONF does not find the failed source information:
