How can I import the Maven shade plugin properly?

I am very frustrated. I’ve spent a long time trying to compile a Maven project into an Uber/Fat jar file using the Maven shade plugin, but I still keep getting “mvn is not recognized as an internal or external command” error in command prompt. Here are the important bits of my pom.xml:

    <build>
<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>3.2.4</version>
    <executions>
      <execution>
        <phase>package</phase>
        <goals>
          <goal>shade</goal>
        </goals>
        <configuration>
          <transformers>
            <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
              <mainClass>*my main class*</mainClass>
            </transformer>
          </transformers>
          <filters>
            <filter>
                <artifact>*:*</artifact>
                    <excludes>
                        <exclude>META-INF/*.SF</exclude>
                        <exclude>META-INF/*.DSA</exclude>
                        <exclude>META-INF/*.RSA</exclude>
                    </excludes>
                </filter>
            </filters>
        </configuration>
      </execution>
    </executions>
  </plugin>
</plugins>

I don’t know what I’m doing wrong. I am going into my project’s directory using Windows Command Prompt and typed “mvn clean install” but it doesn’t seem to work. I am new to Maven, I generally use Gradle. Has the plugin not loaded? Am I doing something wrong? Or am I just being stupid as always?

Any help appreciated! Thanks in advance!

Answer

For Maven to work on command line, you need to

download and unzip it to some directory
Add the bin directory in that directory to your PATH

If you have done that, you may have a type or may need to restart your system.
