[MDSAL-651] yang-maven-plugin:6.0.2 error while generating sources

Relates — Fri, 8 Jan 2021 11:36:37 +0000

Hello,

After upgrading yang-maven-plugin from 6.0.0 to 6.0.2, the
generation of java classes failed for
org-openroadm-device@2020-05-29.yang file.
The following error is displayed:

The problem seems located in
leaf-list port-list {
type leafref

{ path "/org-openroadm-device/circuit-packs[circuit-pack-name=current()/../circuit-pack-name]/ports/port-name"; }

description
"port list";
}

When generating setter, the object returnType is an empty List and
does not contain the type of the objects in the list portList.
Trace from remote debug:
MethodSignatureImpl [name=getPortList,
comment=TypeMemberComment

{reference=port list}

,
definingType=org.opendaylight.yang.gen.v1.http.org.openroadm.device.rev200529.supporting.circuit.pack.list.grp.SupportingPortList,
returnType=Type (java.util.List), params=[], annotations=[]]

I’ve attached a sample to reproduce the problem and the output log of
the maven command.

Thanks in advance for your help
