I can't add dependencies to my Confluence plugin

[Mikel Rodriguez]

Whenever I add a dependency to connect to databases to my Confluence plugin I get this exception:

org.osgi.framework.BundleException: Unable to resolve [...]: missing requirement [...] osgi.wiring.package; (osgi.wiring.package=com.mchange.v2.c3p0) Unresolved requirements: [...] osgi.wiring.package; (osgi.wiring.package=com.mchange.v2.c3p0)]

The dependency I'm trying to add is

<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.48</version>
</dependency>

How can I fix this?

Hi @Mikel Rodriguez 

I exactly recall this problem in Jira plugins, and I know it's tough to solve. 

What I'd suggest is to add the <Import-Package> section into your <instructions> element under the pom configuration and make the relevant packages optional. Otherwise you need to add all related dependencies to your pom.xml

Here it seems that "com.mchange.v2.c3p0" package needs to be done optional but if you add this other packages might throw similar errors.

<Import-Package>
    com.mchange.v2.c3p0;resolution:="optional",
    *
</Import-Package>

 Hope it was helpful
