I just resolved an 

failed.org.hibernate.internal.util.config.ConfigurationException: Unable to 
perform unmarshalling at line number 0 and column 0 in RESOURCE  
hibernate.cfg.xml.

error building my own app.

The solution was actually very simple, namely I was missing dependencies in my pom.xml file. I had just one:

...
<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.1</version>
</dependency>
...

Adding the three below solved the problem:

<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.2.11</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
<version>2.3.2</version>
</dependency>
<dependency>
  <groupId>javax.activation</groupId>
  <artifactId>activation</artifactId>
  <version>1.1.1</version>
</dependency>

I hope this will help someone.

Please ensure that your "hibernate.cfg.xml" file is present in the "src" folder of your project.
