Postgresql driver not found for maven dependency

Question

I am running a spring project with maven and I am trying to use postgresql. I've added the dependency to pom.xml, but at tomcat startup, I get the following error:

java.lang.ClassNotFoundException: org.postgresql.Driver

pom.xml dependency:

<dependency>
  <groupId>org.postgresql</groupId>
  <artifactId>postgresql</artifactId>
  <version>9.3-1101-jdbc41</version>
</dependency>

It appears that Maven isn't downloading the jar so the Driver class is not found. Any ideas?

Answer 1

Maven wasn't recognizing the new dependency I have added to pom.xml, so I added it through 'Dependency view' from the xml and that did the trick. Thank you for your answers.

Answer 2

What also worked for me if you are on intellj: right klick pom.xml->Maven->Reimport Don't know why it doesn't download the artifact on copy paste.

Answer 3

When I put this in my pom, the artifact gets downloaded. Maybe you should clean your maven repository cache or delete the folders manually and retry.

Answer 4

If you came here for "missing artifact" error, This worked for me:

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

For PostgreSQL 10 I use this:

       <dependency>
            <groupId>org.postgresql</groupId>
            <artifactId>postgresql</artifactId>
            <version>42.1.4</version>
        </dependency>

Answer 5

Try to rebuild the artifact, most likely only the added dependency was not included there

Answer 6

You need to place a copy of the jar in the tomcat/lib folder.
