Where do I put an external dependency in Maven?

[Owen Thomas]

Hello.

Although I have used a build tool for some time, I am only now trying to
use it to manage dependencies to external libraries used by my project. The
first such library I am trying to use is BSON.

I am using a multi-module project, and, possibly because I am ignorant, I
have chosen to insert the dependency in the top level POM of the overall
project, not any of the sub-projects. So, I have inserted the following
dependency (appears in boldface) in the following location of my top level
POM:

<?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>cliquespace</groupId>
    <artifactId>Cliquespace</artifactId>
    <version>0.0-SNAPSHOT</version>
    <packaging>pom</packaging>
    <modules>
        <module>Concept</module>
        <module>PeerDevice</module>
        <module>PeerInitiator</module>
        <module>PeerRespondent</module>
        <module>SwingGUI</module>
        <module>Glion</module>
        <module>Renderer</module>
        <module>Neuron</module>
        <module>RelayNeuron</module>
        <module>PulseNeuron</module>
    </modules>






*<dependencies>        <dependency>
<groupId>org.mongodb</groupId>            <artifactId>bson</artifactId>
        <version>3.8.1</version>        </dependency>    </dependencies>*
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>
</project>

The reason I did this was because I wanted the library to be available
across all of the sub-projects.

However, when I type "import org." into the editor of a source file in the
PeerDevice sub-project, I am expecting the editor to suggest "mongodb", yet
this suggestion does not come up.

What am I doing wrong?

Thanks,

  Owen.

PS: I did try the PeerDevice sub-project and found the same result. Also, I
don't know if this is important or not, but I have a file module-info.java
in the package root directory for each of my sub-projects.
