I am trying to create a FAT jar and combine entries in META-INF/services/io.vertx.config.spi.ConfigProcessor from vertx-config and vert-config-yaml JAR files. I do not see a need for mainfest entry options for ServicesResourceTransformer, but I am experiencing the error: 

Unable to parse configuration of mojo org.apache.maven.plugins:maven-shade-plugin:3.2.1:shade for parameter manifestEntries: Cannot find 'manifestEntries' in class org.apache.maven.plugins.shade.resource.ServicesResourceTransformer -> [Help 1]

At first, I did not add the line 

<transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer" />

and the manifest entries did not get merged and one of the class from vert-config-yaml is missing. Now I add the line as below, and I see the error. I am using maven-shade-plugin plugin version 3.2.1. What am I doing wrong here?

        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-shade-plugin</artifactId>
          <version>${maven.shade.version}</version>

              </filters>
                <transformers>

                  <transformer

                  </transformer>

                  <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer" />

Try adding <id> to your execution:

<execution>
  <id>shade-my-jar</id>
  <phase>package</phase>
    <goals>
      <goal>shade</goal>
    </goals>
</execution>
