Я пытался собрать некоторые из плагинов UMLDesigner, но произошла ошибка создания экземпляра.Это xml-файл pluginplugin.xml: <?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.4"?>
<plugin>
<extension point="org.eclipse.sirius.componentization">

This is the error message:

Согласно umlDesigner, весь исходный код проекта сообщается неправильно, поэтому я взял некоторые плагины umlDesigner и запустил его.
