 Description   

[ERROR] yang-to-sources: Unable to generate sources with org.opendaylight.yangtools.maven.sal.api.gen.plugin.CodeGeneratorImpl generator
java.lang.IllegalArgumentException: Type cannot have Package Name referenced as NULL!
at com.google.common.base.Preconditions.checkArgument(Preconditions.java:88)
at org.opendaylight.yangtools.sal.java.api.generator.GeneratorUtil.putTypeIntoImports(GeneratorUtil.java:138)

package name cannot be null, problem with hard-coded UnionType class:

public static final class UnionType implements Type {
@Override
public String getPackageName() {
return null;

just to add, based on analysis of this issue:

error occurs when using imported typedef based on union type:

module module1 {

import module2

{ prefix m2; }

container foo {
leaf address {
type m2:host {
}
}
}
}

module module2 {
typedef host {
type union

{ type int8; type string; }

}
}

Error doesn't occur if:
1) imported typedef is not based on union type

typedef host

{ type string; }

2) typedef host is inside of module1

Currently developed openconfig models trigger this Bug.
(Several of the models, mostly related to BGP, RIB and MPLS.)

being fixed as part of types resolution within Binding generator for v2
