[MDSAL-423] Failed to find leafref target

Duplicate — Sun, 22 Dec 2019 12:16:04 +0000

Team,

I am facing an issue related to "Failed to find leafref target" when trying to generate java classes using org.opendaylight.mdsal.binding.maven.api.gen.plugin.CodeGeneratorImpl. It would be very helpful if you could review this issue at the earliest and suggest a way to resolve this. Thank you in advance.

Attached below is the snippet of pom.xml that I had used for generating the java classes:
