Packaging plugin error

UE5.1

Help, I have created two plugins, PluginA and PluginB. I am calling a function from PluginB within PluginA. I have added PluginB in the .cs file. When I try to package PluginA, it gives an error saying it cannot find PluginB.

Below is the screenshot of the error and the project with the error.

Thanks for reply，I want to package pluginA in the way shown in the picture.

KryogenicGames · May 22, 2024, 7:46am

so what worked for me add plugin B as dependant plugin to pluginA

i removed pluginB listed in pluginA.build.cs

then package pluginB, it packaged both plugins

Could you please send me the modified project?

KryogenicGames · May 22, 2024, 8:08am

try it

so when you package pluginB it packages both plugins

AFei · May 22, 2024, 9:03am

Thank you for your response.

I tried opening the project and packaging the PluginB plugin, and it was successful, but the target directory only contains one plugin.

So I tried packaging PluginA to the same directory again, but it failed. However, I found a HostProject project in this directory, and my A plugin is inside it."

“I checked the log for packaging PluginA, and it indicated that PluginB was missing, which seems a bit illogical.”

error log

Unable to find plugin 'pluginB' (referenced via command line -> pluginA.uplugin). Install it and try again, or remove it from the required plugin list.

i will investigate and let you know.

Update:
Whole project packages fine, project compiles fine in VS but when you try to use package option on plugin its doesnt work. I failed to package plugin way you want. Sorry

No worries, thank you for all your help. It’s possible that the current engine version doesn’t support this approach anymore. I’ll try other methods.
