Hi!
I recieved this warning when I execute my app:
sep 22, 2018 5:59:36 PM org.hibernate.service.jdbc.connections.internal.ConnectionProviderInitiator c3p0ProviderPresent
WARN: HHH000022: c3p0 properties were encountered, but the org.hibernate.service.jdbc.connections.internal.C3P0ConnectionProvider provider class was not found on the classpath; these properties are going to be ignored.
The problem is: I’m using Hibernate-core-5.2.6.jar (with all his libraries), C3p0-0.9.5.2.jar and hibernate-c3p0-5.2.6.Final.
It should work. But It doesnt. What I’m doing wrong?
Hi vlad! Thanks for your answer

Yes, you can use c3p0 without a build tool. But, in a real project you’ll always use Maven or Gradle, and posting the pom.xml is how we could help you.
If you’re setting your project in the IDE alone, only you will ever know what you are doing there.
I have a doubt, I transformed my project to Maven and I added all the dependencies. But the “Query” appears deprecated, and I have the same jars (dependencies). Am I doing something wrong?
Thanks @vlad !
I do this, but I recieve this erros:

It means you have an older version of Hibernate on your classpath.
After you migrate your project to Maven, you need to run the following command:
mvn dependency:tree
and see what versions of Hibernate you have set up in your project. This will prove that you are not seeing multiple versions of Hibernate which can lead to that problem.
In the command line, in the project root folder. You need to read the documentation of Maven as well. There’s no other way to learn all these tools and frameworks.
