JHipster - Running liquibase:diff fails due to "Access denied" - mysql

Question

When adding a field to an Entity in JHipster, the last step (when using MySQL) is running
./mvnw compile liquibase:diff
As per the docs at https://jhipster.github.io/development/
However, this doesn't work for my rather simple install, because the process doesn't use the correct MySQL user and pass. My app runs fine in dev profile, but not like this.
Where does Liquibase get its credentials from?
Below you can see the output.

You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

It first appears the correct settings are used. My DB is called "imicloud", but then later the error is:
java.sql.SQLException: Access denied for user 'root'#'localhost' (using password: NO)
Obviously I am using a password for MySQL.
How to fix this?
I guess I missed an essential setup step as this is the first time I'm using the liquibase:diff command.

Answer 1

The credentials used by the mvn liquibase commands are found in you pom.xml, in the liquibase plugin's configuration tag. The section of the pom.xml looks like:
<plugin>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-maven-plugin</artifactId>
<version>${liquibase.version}</version>
<configuration>
<changeLogFile>src/main/resources/config/liquibase/master.xml</changeLogFile>
<diffChangeLogFile>src/main/resources/config/liquibase/changelog/${maven.build.timestamp}_changelog.xml</diffChangeLogFile>
<driver>com.mysql.jdbc.Driver</driver>
<url>jdbc:mysql://localhost:3306/ng2</url>
<defaultSchemaName>ng2</defaultSchemaName>
<username>root</username>
<password></password>
<referenceUrl>hibernate:spring:com.mycompany.myapp.domain?dialect=org.hibernate.dialect.MySQL5InnoDBDialect&hibernate.physical_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy&hibernate.implicit_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy</referenceUrl>
<verbose>true</verbose>
<logging>debug</logging>
</configuration>
...

Answer 2

Configure your Spring Boot properties accordingly in your src/main/resources/config/application-.yml or application-.properties files
Add end with your database URL like this.
url: jdbc:mysql://localhost:3306/imicloud?u‌​seSSL=false
