shade for parameter resource: Cannot find 'resource' in class org.apache.maven.plugins.shade.resource.ManifestResourceTransformer

Specific error as follows:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:3.2.4:shade (default) on project mqtt-sim: Unable to parse configuration of mojo org.apache.maven.plugins:maven-shade-plugin:3.2.4:shade for parameter resource: Cannot find 'resource' in class org.apache.maven.plugins.shade.resource.ManifestResourceTransformer -> [Help 1]

But there is clearly no resource-related configuration in the plugin configuration; the reason here is:

Because the execution did not have an id written, it conflicted with other tasks without ids, mixing in resource configurations from other tasks, causing failure.

Solution: Add an id

<execution>
    <id>ctbots-uniq-id</id>
    <phase>package</phase>
    <goals>
        <goal>shade</goal>
    </goals>

This will resolve the error
