I am building a module and trying to upgrade the version of the SDK that I am compiling against to match what I currently have deployed out in the field. Moving my SDK version up to 8.1.17, I get an error saying that "the following artifacts could not be resolved". The list of the artifacts missing includes "ignition-common", "gateway-api", and more. Browsing the artifact repository, I do see a 8.1.17-rc1 but would prefer to actually use the full release files. I know there was a similar issue back in October with Perspective. Is there any way to get the 8.1.17 republished? Tagging @KathyApplebaum @PerryAJ since you got it working last time. ---

In the short term (I can't help with the artifact release process), why not just compile your module against 8.1.16? I don't think there's any significant changes that will impact you between the two. ---

I am trying to import the following. com.inductiveautomation.ignition.designer.gui.tools.ExtensionFunctionPanel; It does not exist in 8.1.16 but it exists in 8.1.18 and Im really really hoping it exists in 8.1.17. ---

Unfortunately it does not; it was part of 8.1.18. ---

Well thats not good news for me then. Those upgrades are going to be a lot of fun then. Is there documentation on how to do a project resource editor before 8.1.18 then? ---

The core APIs for a project resource editor are still basically the same. The ExtensionFunctionPanel piece is only needed if you want to provide a (good) **script** editing experience for your end users. If you just want to provide _some other type of editor_, you absolutely still can. If you do specifically need scripting, _and_ you're stuck on 8.1.17, you can look at the CodeEditorFactory class for the now legacy Jidesoft based CodeEditors that used to be used in the software.
