| [p2-dev] Inconsistent custom action behavior |
Hello, I am trying to execute a custom action during installation of a feature in the Eclipse CDT distribution. While this works correctly in most cases, I am finding that on some machines the installation results in the following error: "An error occurred while configuring the installed items session context was:(profile="" phase=org.eclipse.equinox.internal.p2.engine.phases.Configure, operand=null --> [R]com.iar.cdt.arm.debugger.feature.feature.group 0.12.0.v201111101709, action=""> No action found for: com.iar.installer.arm.resetDsfStepDelay. No action found for: com.iar.installer.arm.resetDsfStepDelay." The action is declared in the following p2.inf file provides.0.namespace=org.eclipse.equinox.p2.engine.actions provides.0.name=com.iar.installer.arm.resetDsfStepDelay provides.0.version=1.1 and the plugin containing the action itself (com.iar.installer.arm) declares it like this <extension point="org.eclipse.equinox.p2.engine.actions"> <action class="com.iar.installer.arm.actions.ResetDsfPreferencesAction" name="resetDsfStepDelay" touchpointType="com.iar.hubble.releng.touchpoint" touchpointVersion="1.0" version="1.1"> </action> </extension> <extension point="org.eclipse.equinox.p2.engine.touchpoints"> <touchpoint class="com.iar.installer.arm.touchpoints.ResetPreferencesTouchpoint" type="com.iar.hubble.releng.touchpoint" version="1.0"> </touchpoint> </extension> The p2.inf file for the feature requiring the action is metaRequirements.0.namespace=org.eclipse.equinox.p2.engine.actions metaRequirements.0.name=com.iar.installer.arm.resetDsfStepDelay metaRequirements.0.range=1.1 instructions.configure=com.iar.installer.arm.resetDsfStepDelay(); As I mentioned, this works correctly in most cases, but on some machines it fails with the reported error. As the plugins are unsigned, I can see the p2 dialog asking for unsigned install twice: first for the plugin containing the action and its dependencies, and then for the feature requiring the action. After the error has appeared, the plugin containing the action and its dependencies are installed, while the feature using the action has not. As this is the first time I am using custom p2 actions, I am unsure whether I am doing things in the correct way. There seems to be no specific system configuration which is associated to the failure. Thanks for your help! /Mario Pierro |
