Why don't my maven nested dependencies appear at compile time

Question

I have a library called my-library that I packaged with Maven and stored in a private Nexus repository. It compiles correctly and loads into my repo and has the following dependencies specified in the file pom.xml:

<dependencies>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jcl-over-slf4j</artifactId>
        <version>1.7.13</version>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>com.google.protobuf</groupId>
        <artifactId>protobuf-java</artifactId>
        <version>3.1.0</version>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>
        <scope>test</scope>
    </dependency>
</dependencies>

I am including this dependency in another my-child-project using the following blocks pom.xml:

<repositories>
    <repository>
        <id>MyRepo</id>
        <name>My Maven Repository</name>
        <url>http://localhost:8081/nexus/repo</url>
    </repository>
</repositories>
...
<dependencies>
    <dependency>
        <groupId>com.my.group</groupId>
        <artifactId>my-library</artifactId>
        <scope>compile</scope>
        <version>1.0.0</version>
    </dependency>
</dependencies>

mvn clean install my-child-project, , maven my-library, com.google.protobuf pom.xml my-child-project. , Maven , mvn dependency:tree:
