Description

curl -X POST -H 'Content-type:application/json' --data-binary '
{
  "add-package": {
       "name": "my-package" ,
      "sha512":"<the-sha512>"
  }
}' http://localhost:8983/api/cluster

This means that Solr creates a globally accessible classloader with a name my-package which contains all the jars of that package.
A component should be able to use the package by using the "package" : "my-package".
eg:

curl -X POST -H 'Content-type:application/json' --data-binary '
{
  "create-searchcomponent": {
      "name": "my-searchcomponent" ,
      "class" : "my.path.to.ClassName",
     "package" : "my-package"
  }
}' http://localhost:8983/api/c/mycollection/config
