Cannot determine embedded database driver class for database type NONE while running jar

Question

As mentioned in the headline of question I am facing issue Cannot determine embedded database driver class for database type NONE. The application I have built is on spring boot and working fine when I run the code in intellij.

I have followed several questions regarding the same exception and they suggested that I need to add spring.datasource properties in my application.properties file. I already have them and still facing the same issue. This issue occurs when I create jar file using artifacts of intellij and then run it by the following command. java - jar myJar.jar

My application.properties file

# ===============================
# = DATA SOURCE
# ===============================
spring.datasource.url = jdbc:mysql://localhost:3306/db_wssmith?useSSL=false
spring.datasource.username = 
spring.datasource.password = 
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

Error Log while running jar

ERROR org.springframework.boot.SpringApplication - Application startup failed org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Tomcat.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.tomcat.jdbc.pool.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

Solution

You should create the jar from maven, to do that go to View on top then Tool Windows/Maven Projects and from there double click on install in LifeCycle option in maven. Use the jar created by that command instead of using intellij. It Should work.
