<p>When I look on Maven Central, I can find the dependency here: <a href="https://repo1.maven.org/maven2/com/mchange/c3p0/0.9.5.2/" rel="noreferrer">https://repo1.maven.org/maven2/com/mchange/c3p0/0.9.5.2/</a></p>

<p>I know I have to be doing something stupid, please help me so I can eat some crow and move on.  </p>

<p>Thanks,
Tony</p>
