Description

am trying to pass Map kind of parameters to my maven plugin through command line. Here is how i tried,

$mvn -U -X sample.plugin:hello-maven-plugin:1.0-SNAPSHOT:sayhi -Dsayhi.myMap=key1=value1

$mvn -U -X sample.plugin:hello-maven-plugin:1.0-SNAPSHOT:sayhi -Dsayhi.myMap={key1=value1}

None of these are working and getting following error:

Caused by:
org.codehaus.plexus.component.configurator.ComponentConfigurationException:
Cannot assign configuration entry 'myMap' with value '${sayhi.myMap}' of type
java.lang.String to property of type java.util.Map

Here is my parameter in Mojo:

/**

• My Map.
  */
  @Parameter(property = "sayhi.myMap", required = false)
  private Map<String,String> myMap = new HashMap<String, String>();

followed instructions at ==> https://maven.apache.org/guides/mini/guide-configuring-plugins.html#Mapping_Collections, but no luck., i think am missing something very small. am working on maven v3.2.1

is am missing anything here ? am blocked on this.

i have also posted same question stackoverflow.
