ClassNotFoundException: org.postgresql.Driver

[Andrey Dmitriev]

 Hello!

 I have the following maven-dependency:

<postgresql.version>42.2.11</postgresql.version>

    <dependency>
        <groupId>org.postgresql</groupId>
        <artifactId>postgresql</artifactId>
        <version>${postgresql.version}</version>
    </dependency>

 Project-properties:

<java.version>11.0.6</java.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

        <spring.version>5.2.4.RELEASE</spring.version>
        <spring-data-jpa.version>2.2.5.RELEASE</spring-data-jpa.version>
        <tomcat.version>9.0.27</tomcat.version>

And try to use it by spring-xml-configuration:

<bean id="dataSource"
      class="org.apache.tomcat.jdbc.pool.DataSource"
      p:driverClassName="org.postgresql.Driver"
      p:url="${database.url}"
      p:username="${database.user}"
      p:password="${database.password}"/>

But during deployment I receive:

[code=java]
java.lang.ClassNotFoundException: org.postgresql.Driver
at java.base/java.net.URLClassLoader.findClass(URLClassLoader.java:471)
at java.base/java.lang.ClassLoader.loadClass
.....

SDK is 11.0.6.

I tried:
1. Rebuild project.

2. Invalidate Caches/Restart

3. Maven Clean/Install.  But Install failed by the reason of:

 
     Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project user_service: Fatal error compiling


Help me, please!!!  I almost a day battle with this problem

  I'm still "anchored"....

It says "error in compiling", so the problem is with the Java code. Is there no stack trace, or an indication in which line of code the error happens?
