Install postgresql driver for plugin

[valerian Baillet]

Hi,

I try to read the jira service desk database from a plugin that I created. I use a postgresql database.

I try to add a dependency to pom.xml :

 <dependency>
     <groupId>org.postgresql</groupId> 
     <artifactId>postgresql</artifactId> 
     <version>9.4.1212</version> 
</dependency>

 I have a lot of error like Found a type [com.atlassian.plugin.spring.scanner.annotation.imports.StashImport] annotated as a component, but the type is not a concrete class. NOT adding to index file!!

I try to use a provided scope for this dependency but when I use my plugin, I add an error that postgresql driver doesn't exist. That's happen when I use this line code.

private static final String DB_DRIVER = "org.postgresql.Driver";
Class.forName(DB_DRIVER);

Somebody know how can I connect my plugin on jira database ?

Best regards
