Where can I get the plug-in container?

Question

So i'm trying to get into plug-in development, but i'm failing to find them. Originally, I went to <appian_home>/ear/suite.ear/lib within my local install to try and locate the libraries that were were stated in the one of the training videos in regards to plug-ins. However, when looking in <appian_home>/ear/suite.ear/lib for the following:

com.appiancorp.services
com.appaincorp.common
com.appiancorp.type
com.appiancorp.suiteapi

I wasn't able to locate them. In addition, I was looking at an 18.2 local install as well. I did try looking at an 18.3 install, but I was unable to find <appian_home>/ear/suite.ear/lib.

Then, I went on community and found the following link, https://docs.appian.com/suite/help/18.3/Custom_Plug-in_Packages.html. Within this link it does state that the packages listed are provided by the plug-in container.

So, overall my question is, where can I get this plug-in container package? Or is there another place I can locate the libraries?

Please let me know if there is any other info I can provide.

Thank you,

For development purposes, you don't need the "container". All that means is essentially all of those classes are available in the plug-in runtime environment - in other words, if your plugin uses one of those packages/classes, you don't need to include an external JAR inside the plugin JAR. Classes *not found* on that list, will need JARs within the plugin JAR. 
 
I would recommend checking out this article for guidance on creating a plugin and what external files you need - docs.appian.com/.../Custom_Smart_Service_Plug-ins.html
