Sure,
Although, after trying several combinations, I remove the file itself from the entire project and tried it again. And the result was the same, "Could not parse work definitions MyWorkDefinitions.conf:null"
But nevertheless, the file is the following:
import org.drools.process.core.datatype.impl.type.StringDataType;
[
// the Notification work item
[
"name" : "Notification",
"parameters" : [
"Message" : new StringDataType(),
"From" : new StringDataType(),
"To" : new StringDataType(),
"Priority" : new StringDataType(),
],
"displayName" : "Notification"
]
]
