I am hitting the below error while generating java pojos using json schema.

I downloaded the bundle - www.dmtf.org/sites/default/files/standards/documents/DSP8010_2018.1.zip

Not being familiar with that tool, I'm afraid we're going to need a lot more information to know whether this is a problem with our schemas or with the tool... We've seen a number of json schema tools that don't handle external references or 'definitions' correctly per the json schema spec, too.

One issue I did find recently is that our schemas reference our extensions for the $schema, as in: redfish.dmtf.org/schemas/v1/redfish-schema.v1_1_0.json but the redfish-schema references itself instead of the json-schema, and if you hand-edit redfish-schema.v1_1_0.json with: "$schema": "http://json-schema.org/draft-04/schema#" you can see if that is the root issue for the pojo tool or not.

We'll discuss this in the Redfish Forum and see if reaching out to the tool developer can perhaps get some insight - as those error messages aren't particularly helpful for diagnosing the issue without digging into the code...

I was using the same jsonschema2pojo library to generate Java classes from JSON Schemas. I got the same error (Path not present: Operations) for 4 files. These files are:
Drive.v1_1_0.json
Drive.v1_1_1.json
Drive.v1_1_2.json
Drive.v1_2_0.json

In these files the 'Operations' schema is defined like:
"Operations": {
"type": "array",
"items": {
"$ref": "http://redfish.dmtf.org/schemas/v1/Volume.v1_0_0.json#/definitions/Operations"
},
"description": "The operations currently running on the Drive.",
"longDescription": "This property shall contain a list of all operations currently running on the Drive."
}

In other 'Drive' schema files the 'Operations' is defined as:
"Operations": {
"additionalProperties": false,
"description": "An operation currently running on this resource.",
"longDescription": "This type shall describe a currently running operation on the resource.",
"patternProperties": {
"^([a-zA-Z_][a-zA-Z0-9_]*)?@(odata|Redfish|Message)\\.[a-zA-Z_][a-zA-Z0-9_.]+$": {
"description": "This property shall specify a valid odata or Redfish property.",
"type": [
"array",
"boolean",
"integer",
"number",
"null",
"object",
"string"
]
}
}

I am not sure if this is the issue with the 'jsonschema2pojo' library I am using or the schema file is not proper. I will keep checking how to get rid of this issue and generate Java classes successfully. But just wanted to give some more insight in this thread.
Any help here will be appriciated.

- thanks

Thanks for this information. That allowed me to locate the issue, which is a problem with those versions of the Drive schema. In v1.1.0 the "Operations" property was added, which references a definition in the Volume schema. But the reference is incorrect ("Operation" not "Operations"). In later versions that property is updated to use a local reference which also happens to correct this error. You can easily work around this issue with your process by just removing these 4 schemas from the "anyOf" array in Drive.json to avoid those files completely.

This raises a question for us about the inclusion of all errata versions of a schema in the JSON schema "un-versioned" file, where just the "highest errata" version of each (minor release) schema would accomplish the goal without subjecting the tools to schema bugs that were later corrected.

I'll discuss this with the group - thanks again for the detailed post!

Thanks Jeff for looking into this.

Actually I was trying to generate Java classes to represent Redfish resources, so I was trying them from JSON Schema files. But honestly I am still struggling to manage it properly. If you have any suggessions or can point me to any resource, it will be very helpful.

- thanks
