i'm trying to connect grails to mysql but i get this error:

Change runtime 'mysql:mysql-connector-java:5.1.23-bin'
to
runtime 'mysql:mysql-connector-java:5.1.34'
That should pull in the dependency correctly.

Why did the quality of the GUI deteriorate by half after creating the exe file with jpackage?

I'm using jpackage to convert the jar file to an exe, with the exe file provided by the internal JRE. As a result of the conversion, good results were obtained, the JRE weighs about 38.5 mb.
When I run the exe, the GUI quality is twice as WORSE as in a normal jar! In addition, the window of the new exe file increases on its own. Thus, very strange changes appear, as if the exe file is trying to imitate a window jar file. I want to point out that I am using libGdx for the GUI.

ERROR pool.ConnectionPool - Unable to create initial connections of pool

your driverClassName is wrong. use the correct one for mysql (in the environments, e.g. com.mysql.jdbc.Driver), where you need mysql. right now you have:
default: driver=h2, dialect=mysql;
dev: url=mysql
prod: url=h2
you definetly want to clean this up. also make sure, you have the driver in your deps.

how to connect mysql database in grails with intellij IDE

I am new to grails and intellij ide. I have run a grails project in intellij that's ok. But now I need to use mysql database instead of default. I have no idea how to do it. As much as I know i have changed my datasource class like below >>>
dataSource {
pooled = true
driverClassName = "com.mysql.jdbc.Driver"
dialect = "org.hibernate.dialect.MySQL5InnoDBDialect"
properties {
initialSize = 5
maxActive = 10
minIdle = 5
maxIdle = 5
maxWait = 100000
validationQuery = "select 1"
minEvictableIdleTimeMillis = 60000
timeBetweenEvictionRunsMillis = 60000
}
}
hibernate {
cache.use_second_level_cache = false
cache.use_query_cache = false
cache.provider_class = 'net.sf.ehcache.hibernate.EhCacheProvider'
}
// environment specific settings
environments {
development {
dataSource {
dbCreate = "update" // one of 'create', 'create-drop','update'
loggingSql = true
url = "jdbc:mysql://localhost/sbicloud_jan_13"
username = "root"
password = "admin"
}
}
test {
dataSource {
dbCreate = "update"
url = "jdbc:mysql://192.168.18.12/sbicloud"
username = "zia"
password = "zia123321"
}
}
production {
dataSource {
}
}
}
when I run the app some errors occur in console and the first is as below >>>
Cannot load JDBC driver class 'com.mysql.jdbc.Driver'
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
Can anyone please help me on this?! It will be so helpful for me.
There are more or less 2 approaches:
Modify your BuildConfig.groovy so your application will use MySQL. In the BuildConfig there is a block called 'dependencies'
dependencies {
// specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes eg.
// runtime 'mysql:mysql-connector-java:5.1.20'
}
