I'm launching the application with java -jar neo4jtestapi-0.0.1-SNAPSHOT.jar or via springboot eclipse plugin or even with mvn clean install/mvn clean package
I noted a strange behavior which is when I execute mvn clean install or 'mvn package' and then run springboot eclipse plugin, then it fails with the error
Error: Could not find or load main class com.myapp.interview.api.Neo4jtestApiApplication
Any idea please ? This is preventing me from launching the application in my EC2 instance now..
