Intellij not recognizing Dropwizard version dependency

I've started to create a java project using the dropwizard framework and maven. My pom.xml file looks like
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>org.dexcane</groupId>
<artifactId>dexcane-backend</artifactId>
<version>1.0-SNAPSHOT</version>
<properties>
<maven.compiler.source>17</maven.compiler.source>
<maven.compiler.target>17</maven.compiler.target>
<dropwizard.version>2.1.4-SNAPSHOT</dropwizard.version>
</properties>
<dependencies>
<!-- https://mvnrepository.com/artifact/io.dropwizard.archetypes/dropwizard-archetypes -->
<dependency>
<groupId>io.dropwizard</groupId>
<artifactId>dropwizard-core</artifactId>
<version>2.1.4-SNAPSHOT</version>
<type>pom</type>
</dependency>
</dependencies>
</project>
I'm following the dropwizard tutorial. When I hover over the "2.1.4-SNAPSHOT" dependency Intellij says "Dependency 'io.dropwizard:dropwizard-core:2.1.4-SNAPSHOT' not found ". Does anyone know what's wrong with the import? The tutorial says the current version of dropwizard is 2.1.4-SNAPSHOT.

You shouldn't add it with the type of pom as its packaging is jar.

Issue adding MongoDB Java Driver as a Maven dependency

The title says it all really, my pom is shown below:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>org.example</groupId>
<artifactId>CouncillorsApp</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>3.12.6</version>
</dependency>
</dependencies>
</project>
The following error is given:
"Dependency 'org.mongodb:mongodb-driver-sync:3.10.2' not found"
I'm using Java 14.0.2 and the latest version of IntelliJ

please read installation
you can try this
<dependencies>
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongodb-driver</artifactId>
<version>3.12.6</version>
</dependency>
</dependencies>

So after restarting IntelliJ the above code seems to work fine. I'm unsure of where the issue was, but the dependency is being found now without any changes to the pom.

Java: invalid source release: 9

I have created a maven project in IntelliJ, I downloaded the dependencies that I need and I can see there are no errors in the code.
I am still getting this error even though I have set Java 8 in project in Project Settings
This is what my pom.xml looks like:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>multithreadedCalls</groupId>
<artifactId>multithreadedCalls</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5.10</version>
</dependency>
</dependencies>
</project>

Just change java version on the second screenshot

That's how I made it work.
File -> settings and then went to this window and updated compiler version from the dropdown.
