Configuring Grails 3 for Postgresql - postgresql

Question

I've been trying to get grails 3 to connect to postgres and cannot get a connection.
This is in my build file: runtime "org.postgresql:postgresql:42.2.5"
and the application.yml datasource:
dataSource:
pooled: true
jmxExport: true
driverClassName: 'org.Postgresql.Driver'
dialect: 'org.hibernate.dialect.PostgreSQLDialect'
username: 'okcomputer'
password: ''
environments:
development:
dataSource:
dbCreate: create-drop
url: jdbc:postgresql://localhost:5432/test
test:
dataSource:
dbCreate: update
url: jdbc:postgresql://localhost:5432/test
production:
dataSource:
dbCreate: none
url: jdbc:postgresql://localhost:5432/test
properties:
jmxEnabled: true
initialSize: 5
maxActive: 50
minIdle: 5
maxIdle: 25
maxWait: 10000
maxAge: 600000
timeBetweenEvictionRunsMillis: 5000
minEvictableIdleTimeMillis: 60000
validationQuery: SELECT 1
validationQueryTimeout: 3
validationInterval: 15000
testOnBorrow: true
testWhileIdle: true
testOnReturn: false
jdbcInterceptors: ConnectionState
defaultTransactionIsolation: 2 # TRANSACTION_READ_COMMITTED
What am I doing wrong here? I'm sure the database exists and the user/pass is correct, but am not sure what to do in order to troubleshoot.
A full stack trace is available here: https://pastebin.com/THrALVaE
(I'm using java 1.8 and grails 3.3.8)
Theres a surprisingly small amount of information regarding grails and postgres, so thanks to everyone in advance!

Answer 1

The driver name should probably be org.postgresql.Driver instead of org.Postgresql.Driver. Class names and package names are case sensitive on the JVM.
dataSource:
pooled: true
jmxExport: true
driverClassName: 'org.postgresql.Driver'
dialect: 'org.hibernate.dialect.PostgreSQLDialect'
username: 'okcomputer'
