On Windows and OS X, the default password is postgres. But on Linux systems, there is no default password set.

To set the default password: Run the psql command from the postgres user account:

• sudo -u postgres psql postgres

• Set the password:

• \password postgres

Afterwards you have to switch via the console to the directory, where the pom.xml is located. 
Then you have to execute mvn assembly:single and then your executable JAR file with dependencies will be hopefully build. 
You can check it when switching to the output (target) directory with cd ./target and starting your jar with a command similiar to java -jar mavenproject1-1.0-SNAPSHOT-jar-with-dependencies.jar.

I tested this with Apache Maven 3.0.3.
