pom.xml include scalatest intellij not compiling - maven

Question

I've started a relatively new project, and am trying to follow these instructions (maven) to include scalatest in my intellij project: https://www.scalatest.org/install.
I've successfully done these steps to include maven as part of my project: https://www.jetbrains.com/help/idea/convert-a-regular-project-into-a-maven-project.html#add_maven_support
now I have this:

which is angry about the first set of <dependancy>
What am I missing?

Answer 1

<dependency> tag must be enclosed into <dependencies> tag:
<dependencies>
<dependency>
<groupId>org.scalactic</groupId>
<artifactId>scalactic_2.13</artifactId>
<version>3.2.5</version>
</dependency>
<dependency>
<groupId>org.scalatest</groupId>
<artifactId>scalatest_2.13</artifactId>
<version>3.2.5</version>
<scope>test</scope>
</dependency>
</dependencies>
Refer to Maven documentation for the pom.xml syntax reference: Dependency Management.
