@developer0744, thanks for sharing!
Do you - or anyone else - know if, for an android plugin, that url should point to a “jar” file? Would that work?
@Jaime_Alemany unfortunately I don’t know. If @vlads or another guru could weigh in that would be a huge help 
It’s self hosted plugins that’s been enabled for all users now. Documented here: https://docs.coronalabs.com/native/hostedPlugin.html
It’s up to the individual plugin developers to migrate their plugins to a new marketplace. Scott has already launched solar2dmarketplace.com and migrated a number of his own plugins there, and I believe is accepting other vendors, and I’m close to launching solar2dplugins.com which is more like the old marketplace. It’s entirely up to the individual plugin vendors to decide whether to use our marketplaces or set up something of their own, but I’m hopeful people will opt for submitting to all available marketplaces and it’ll end up being as easy to find and activate a plugin as it was before.
@richard11, thank you that explains a lot! Are you saying that there’s currently no way to get the 3rd party plugins that were hosted on the old Corona marketplace (eg, Vungle)?
You can download the files and place them in the appropriate folder within Solar2D manually instead of using the self hosted plugins mechanism, but if you do it this way, Solar2D won’t know to pull in updates to those plugins when available.
There’s talk of setting up a Github repository for all of the open source plugins to be migrated to, but it’s all very much a case of seeing where individual vendors decide to move their own plugins to with everything else.
I also have this doubt, as I add the admob plugin that is now free on Solar2D 2020.3594. Without needing an online market for this. If I download the plugin here https://github.com/coronalabs/com.coronalabs-plugin.admob/releases, which folder do I put in?
If so, where would that folder be? Do I put it in the folder of the application I’m doing or inside the folder of the corona?
Hi richard,
What are those appropiate folders? I do not found any documentation about that.
@vlads referenced this tree recently, but I’ve not tried it myself:
($HOME or $AppData)/Solar2DPlugins/[publisherId]/[plugin]/[build]/[platform]/data.tgz

There’s also talk of building in a plugin import tool to the simulator itself so that Solar2D can drop your downloaded files into the right directories for inclusion.
I already went to that directory, added the folders and even then it is giving an error!

Other plugins work during offline assembly simply move the com.coronalabs folder from the Caches folder to the folder:
/Users/user_name/Solar2DPlugins/com.coronalabs
But unfortunately I was not able to get my plugin to work, I get an error. Here is the topic:
Just to update everyone following this thread, I was able to get the Solar2d plugins to work by upgrading from Mojave to Catalina and upgrading Xcode to 11.4.1, using simulator build 3595. At the moment, I cannot get 3rd party plugins to work from solar2dmarketplace.com. The simulator just crashes when the build starts. More info is available here
Looking into this 
will respond to this in the thread
Hi @Scott_Harrison I used the URL you sent me and I’m still getting this during the build process…

This is mostly likely because you have not clicked the activate button. I am looking at your account an it looks like you have no plugins activated based on your account id you posted in an earlier thread
Hi @Scott_Harrison it’s activated now and the problem is still the same. FYI, the video you have on the Game Center page is broken.
I’m going to use an example project from the sampleCode folder of the Corona build 3595, and simply add the gameCenter to it
@Scott_Harrison ok, so I loaded up sampleCode/Graphics/Fishies/build.settings and I added this…and have the same error as in my project. Can you please try this on your system so we can eliminate the possibility of something happening specific to my computer? I’m running on…
macOS Catalina Version 10.15.4, MacBook Pro (13-inch 2017), 3.3 GHz Dual-Core Intel Core i5, 16GB 2133MHz LPDDR3, Graphics: INtel Iris Plus Graphics 650 1536 MB
My xCode version is: 11.4.1 (11E503a), although I never use it. The Build appears to use it.
So, here’s the only code I added to build.settings to the sample Fishies project.
plugins =
