I have tried already to add the expected dependencies

Maven builds Spring Boot on local machine but not EC2 instance: UnsatisfiedDependencyException

I've been struggling for the past few hours getting Maven to build a JAR file of my Spring Boot project in an Amazon EC2 instance. If I build with IntelliJ or with mvn package in my local computer, everything's fine, no problems. However, if I pull the exact same code from the same repository into the EC2 instance and build it there (both times I use Java 8, have also tried Java 11), it shows this error stacktrace:

I'd really appreciate any help on this issue.

EDIT: Apparently the CourierApplicationTests class was directly at fault: removing it solved my issue. It doesn't really explain why it would build locally and not in EC2, so I'm going to keep this question open and supply the test file:

SQL Server dependency is deprecated, use following to interact with SQL Server
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>6.1.0.jre8</version>
</dependency>
follow links for more information
Configuring Spring Boot for Microsoft SQL Server
Open sourcing the Microsoft JDBC Driver and Maven support

Since it is a REST app, need to add the spring-boot-starter-web dependency in pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>sqljdbc4</artifactId>
<version>4.0</version>
</dependency>
Add also connection properties in config (application.properties by default):
spring.datasource.url=jdbc:sqlserver://localhost;databaseName=springbootdb
spring.datasource.username=sa
spring.datasource.password=replace_value
spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.jpa.show-sql=true
spring.jpa.hibernate.dialect=org.hibernate.dialect.SQLServer2012Dialect
spring.jpa.hibernate.ddl-auto = create-drop
Try that one and see if you can build/run the project.

Change your url parameter to:
spring.datasource.url=jdbc:sqlserver://localhost:1433;databaseName=test1
Port number must be preceded by a colon(":"), not slash("/").

Manually connecting mySQL to eclipse/Spring Boot

I wanted to ask if I need to specify a path to my SQL file when using eclipse and spring Boot? I am given the same error Cannot determine embedded database driver class for database type NONE. All the settings are right, I believe, but the problem is that I never told eclipse where my databases are?
I do have a properties file that states this:
spring.jpa.hibernate.ddl-auto=create-drop
spring.datasource.url=jdbc:mysql://localhost:3306/db_example
spring.datasource.username=springuser
spring.datasource.password=ThePassword
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQLDialect
Is this a way for it to find the db_example, and should it somehow be online when I start my project? When i go to localhost:3306 it also shows an error. I haven't been able to solve this problem in 2 days, and am pretty new to programming so please bear with me!

I dont see your application.properties in the resource folder. Your application.properties is in the test environment instead. i wont work like that.

Please change spring.datasource.driverClassName=com.mysql.jdbc.Driver to this spring.datasource.driver-class-name=com.mysql.jdbc.Driver.
Your final database config may like this:
spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.database-platform = org.hibernate.dialect.MySQLDialect
spring.datasource.url=jdbc:mysql://localhost:3306/db_example
spring.datasource.username=springuser
spring.datasource.password=ThePassword
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
