I had database connection issues on my Java project because of mysql's replacement with mariadb on Debian 10. I am using HikariCP to connect, I updated the code so that it works with mariadb :
HikariConfig hikariConfig = new HikariConfig();
hikariConfig.setMaximumPoolSize(10);
hikariConfig.setDriverClassName("org.mariadb.jdbc.Driver"); // added after internet research about hikaricp and mariadb
hikariConfig.setJdbcUrl("jdbc:mariadb://localhost:3306/" + db);
hikariConfig.setUsername(user);
hikariConfig.setPassword(pass);
I upgraded my HikariCP setup : I replaced 2.7.8 with 3.4.5 (even though I don't know what's the difference) and added the mysql-connector dependency after viewing this post (btw there is no version for this guy's mysql-connector in his pom.xml but I had to put one so I chosed 6.0.6) and I am still getting a Java error :
java.lang.RuntimeException: Failed to load driver class org.mariadb.jdbc.Driver in either of HikariConfig class loader or Thread context classloader
at com.zaxxer.hikari.HikariConfig.setDriverClassName(HikariConfig.java:486)

You are using mariadb now, not mysql. Change
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
<version>6.0.6</version>
</dependency>
to
<dependency>

I am trying to upgrade Spring boot to the version 2.2 together with jetty starter.
I get these errors due to jetty version conflict
The following method did not exist:
'org.eclipse.jetty.websocket.server.NativeWebSocketConfiguration org.eclipse.jetty.websocket.server.NativeWebSocketServletContainerInitializer.initialize(org.eclipse.jetty.servlet.ServletContextHandler)'
The method's class, org.eclipse.jetty.websocket.server.NativeWebSocketServletContainerInitializer, is available from the following locations:
jar:file:/some-dir/target/p3.0.166-SNAPSHOT.war!/WEB-INF/lib/jetty-all-9.4.19.v20190610-uber.jar!/org/eclipse/jetty/websocket/server/NativeWebSocketServletContainerInitializer.class

I have activemq dependency which brings in it's own jetty-all versioned 9.4.19 dependency which is in conflict with spring-boot 2.2 jetty (9.4.20)
And part of my pom.xml is:

Any idea how I can fix this?
ActiveMQ is wrong here.
jetty-all is not meant to be used as a dependency in a project.
See https://www.eclipse.org/lists/jetty-users/msg06030.html
It only exists as a command line tool for the documentation to educate folks about basic featureset of Jetty.
It does not, and cannot, contain all of Jetty.
A single artifact with everything that Jetty produces is impossible.
As #Shilan pointed out, excluding jetty-all is the correct solution.
The use of the other appropriate dependencies (by spring-boot-starter-jetty it seems) will already pull in the correct Jetty transitive dependencies that you need.
You can use $ mvn dependency:tree from the command line to see this (before and after excluding jetty-all)
You might want to run one of the duplicate class finder maven plugins to see what other duplicate classes you have going on and correct for those as well.

I am trying to find the maven dependencies required to successfully run a Hibernate 5 application with MySQL database.
Maven Dependencies for Hibernate5 and for mysql connector:
<!-- Hibernate5 dependecy-->
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>

</dependency>
<!-- MySQL database driver -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.37</version>
</dependency>
The following dependancies needs to be added to successfully run Hibernate 5 with mySQL database.
<dependencies>
<!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-validator -->
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>

I'm using Hibernate Spatial in combination with Postgis and Java Spring Boot.
When my service starts pulling records from the database everything works fine, but the code ends up in org.hibernate.spatial.jts.mgeom.MCoordinate.
I would like to use default measure-less Coordinates instead, because other components of my application are not used to work with MCoordinate (and M-like geometries).
I guess it is a dependency issue? What should I have done differently?
Info:
DATABASE Postgres, Postgis; In my database I have a GEOMETRY field.
dialect org.hibernate.spatial.dialect.postgis.PostgisDialect
ENTITY In my domain class I have the following:
#Column(name="myfield", columnDefinition="Geometry")
#Type(type="org.hibernate.spatial.GeometryType")
private Polygon myField;

I've upgraded my maven dependencies for IBM MQ from these(version: 6.0.2.5):
<dependency>
<groupId>com.ibm</groupId>
<artifactId>mq</artifactId>
<version>${ibm-mq-version}</version>
</dependency>

</dependency>
To that(version: 7.5.0.5):
<dependency>
<groupId>com.ibm</groupId>
<artifactId>mq-jms-all</artifactId>
<version>${ibm-mq-version}</version>
</dependency>
Now, everytime I try to run my project, I get the following error:
nested exception is java.lang.NoClassDefFoundError: Could not initialize class com.ibm.mq.MQEnvironment
The maven-dependency is imported correctly and is also visible in Eclipse in the maven-dependencies-tab. Also i see the com.ibm.mq.jar in the classpath.
I've googled a lot and the only real solution, which worked for some people was, to add the connector.jar. But I'm already using the jar:
<dependency>
<groupId>javax.resource</groupId>
<artifactId>connector</artifactId>
<version>${connector-version}</version>
</dependency>
Am I missing something?
IBM MQ from these(version: 6.0.2.5):
To that(version: 7.5.0.5):
IBM moved the MQException to the 'com.ibm.mq.jmqi.jar' file.
As per the the MQ Knowledge Center, you need the following jar files for MQ JMS programming:
com.ibm.mq.commonservices.jar
com.ibm.mq.headers.jar
com.ibm.mq.pcf.jar
com.ibm.mq.jmqi.jar
connector.jar
jms.jar
dhbcore.jar
rmm.jar
jndi.jar
ldap.jar
fscontext.jar
providerutil.jar
CL3Export.jar
CL3Nonexport.jar
Exactly the same problem and this fixed it
<dependency>
<groupId>javax.resource</groupId>
<artifactId>connector</artifactId>
<version>${connector-version}</version>

For Eclipse (Dynamic Web Project (Servlet)) you need copy files:
com.ibm.mq.commomservices.jar
com.ibm.mq.defaultconfig.jar
com.ibm.mq.headers.jar
com.ibm.mq.jar
com.ibm.mq.jmqi.jar
com.ibm.mq.jms.Nojndi.jar
com.ibm.mq.pcf.jar
com.ibm.mqetclient.jar
com.ibm.mqjms.jar
connector.jar
dhbcode.jar
fscontext.jar
jms.jar
to /WebContext/WEB-INF/lib, then add them into Project (Project -> Properties -> Java Build Path -> Add External JARs).
After all, go through these steps:
close project
close Eclipse
open Eclipse
open project.
Good Luck!
I have a IDEA project using maven2.
I want to use hibernate + mysql, what dependancies do I need?
first of all, I separate the versions from the artifacts:
<properties>
<spring.version>3.0.3.RELEASE</spring.version>
<hibernate.version>3.5.3-Final</hibernate.version>
<mysql.version>5.1.13</mysql.version>
<junit.version>4.7</junit.version>
</properties>
then I reference them like this:
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>${mysql.version}</version>
<!-- perhaps using scope = provided, as this will often
be present on the app server -->
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<!-- or hibernate-entitymanager if you use jpa -->
<version>${hibernate.version}</version>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>${junit.version}</version>
<scope>test</scope>
</dependency>
</dependencies>
That way you keep the versions all in one place and can easily update them, especially if you reference e.g. multiple spring artifacts.
BTW: these should be the current versions, but you can always look up current versions using MvnRepository.com
Pasting these dependencies into pom.xml after <depdendencies> should work:
<!-- MySQL database driver -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.9</version>
</dependency>
<!-- Hibernate framework -->
<dependency>
<groupId>hibernate</groupId>
<artifactId>hibernate3</artifactId>

</dependency>
<!-- Hibernate library dependecy start -->

You may want to tweak the version numbers on the dependencies.
IntelliJ IDEA 9 can find Maven dependencies based on class name. If you start using a class which isn't available in the current dependencies you can get IntelliJ to help find it by using Alt-Enter.
I used this to great effect with a Java-base Subversion hook implementation I am building at work. I was able to get SVNKit and Google Guice dependencies into my project fairly easily this way.
MySQL in your case may be trickier since it is more of a runtime dependency when using Hibernate.
