intellij-platform-gradle-plugin v2.13.1 V1 plugin descriptor Running tests against 2026.1 rc Almost all tests are failing now with 2026.1 rc, because of an unresolved ActionGroup ID. I don’t know how to fix this. The test passes when I remove the reference from plugin.xml, but that’s not what I want to release. I also don’t know if it’s a packaging problem of the IDE or a problem of the intellij-platform-gradle-plugin. Basically the error is `“ERROR: ActionGroupStub (bashpro.SendSignal): group with id “XDebugger.ToolWindow.LeftToolbar” isn’t registered”`. The action was apparently moved to `intellij.platform.debugger.impl.ui.xml` in 2026.1. I already added `bundledModule("intellij.platform.debugger.impl")` to the build setup, but this did not fix the problem. My plugin.xml contains thIs, it refers to “XDebugger.ToolWindow.LeftToolbar” to add a new action to the group: ```auto ``` The full error message: ```auto ERROR: com.intellij.openapi.actionSystem.impl.ActionGroupStub (bashpro.SendSignal): group with id "XDebugger.ToolWindow.LeftToolbar" isn't registered so the action won't be added to it; the action can be invoked via "Find Action" (module=PluginMainDescriptor(name=pro.bashsupport, id=pro.bashsupport, version=261.22158.182, isBundled=true, path=~/self-employment/products/bashsupport-pro/build/resources/test)) [Plugin: pro.bashsupport] com.intellij.diagnostic.PluginException: com.intellij.openapi.actionSystem.impl.ActionGroupStub (bashpro.SendSignal): group with id "XDebugger.ToolWindow.LeftToolbar" isn't registered so the action won't be added to it; the action can be invoked via "Find Action" (module=PluginMainDescriptor(name=pro.bashsupport, id=pro.bashsupport, version=261.22158.182, isBundled=true, path=~/self-employment/products/bashsupport-pro/build/resources/test)) [Plugin: pro.bashsupport] at com.intellij.openapi.actionSystem.impl.ActionManagerImplKt.reportActionError(ActionManagerImpl.kt:1723) at com.intellij.openapi.actionSystem.impl.ActionManagerImplKt.access$reportActionError(ActionManagerImpl.kt:1) at com.intellij.openapi.actionSystem.impl.ActionManagerImpl.getParentGroup(ActionManagerImpl.kt:856) at com.intellij.openapi.actionSystem.impl.ActionManagerImpl.processAddToGroupNode(ActionManagerImpl.kt:815) at com.intellij.openapi.actionSystem.impl.ActionManagerImpl.processGroupElement(ActionManagerImpl.kt:748) at com.intellij.openapi.actionSystem.impl.ActionManagerImpl.registerPluginActions(ActionManagerImpl.kt:432) at com.intellij.openapi.actionSystem.impl.ActionManagerImpl.doRegisterActions(ActionManagerImpl.kt:297) at com.intellij.openapi.actionSystem.impl.ActionManagerImpl.(ActionManagerImpl.kt:198) ``` ---

I tried moving this to `XDebugger.ToolWindow.TopToolbar3.Extra`, but same error. When I try to register the missing group in my test plugin.xml, then the SDK says it’s already registered. This seems like weird packaging or a weird classloader, I guess. For now, I’m unable to solve this. ---

By any chance, does your plugin use plugin model v2? In this case you probably need `intellij.platform.debugger.impl` dependency on runtime dependency graph so the platform sorts action initialization properly. ---

Nope, it’s a v1 descriptor. Adding the module for v1 via `bundledModule(…)`didn’t help. The logs did not show that it wasn’t loaded, but I’m not sure. ---
