Eclipse R2.0 We are using the Eclipse feature support for distributing common plugins to developers workstation. For example: feature_0.0.1 plugina_1.0.5 pluginb_2.0.3 feature_0.0.2 pluginA_1.0.5 pluginB_2.0.4 After updating from feature_0.0.1 to feature_0.0.2, pluginA has been disabled (indicated in the feature's status). The reason seems to be the fact that the same plugin version is included in two different versions of the feature (manually removing the old feature version from the installations resolves the problem) Is there currently any workaround for this problem?
Hum, this should work fine Can you pos the testcase ? (i can try to recreate it, but the exact same testcase will 1) same me time ;-) 2) same more time if I cannot reproduce it with my testcase ;-)
sorry, but i can't provide the plugins used. But it's really that simple ;) - if your test case doesn't work, I can try to create one from scratch for you.
Well, I tried ;-) I got 2 features RedDot 1.0.0 -> plugin 1.0.0 RedDot 1.0.1 -> plugin 1.0.0 I install RedDot 1.0.0, I can see Feature 1.0.0 and plugin 1.0.0 from Help I update to RedDot 1.0.1, I can see Feature 1.0.1 and plugin 1.0.0 from Help
Okay, you've won. I have to admit that it's a little more complicated issue than I thought in first place: you need three plugins. Everything works fine as long as you only have installed two versions of the feature (meaning: two installed, one active in the configuration). If you install the third one, after Eclipse has restarted the active feature shows an error icon in the Update Manager. Status: The feature is not configured properly. No plugin: "..." included at runtime. I attached a stripped down update site for you. (Content has been stripped off the plugins except for the plugin.xml/plugin.properties).
Created attachment 1722 [details] Update site for reproducing the bug
Reproduced, boost priority and severity
Finally found it ;-) the calculation of included/excluded plugin is a delat between the included of the enable feature and the excluded of the disable feature. In this scenario, the calculation found 2 excluded plugins instead of realizing they were the same. So the delta always kept one. Changed the code to use a Set instead of a List for excluded plugins. Tested with own testcase. Provide in 2.0.1 stream
