我已经编写了一个简单的Eclipse插件来从命令行导入首选项，这看起来效果很好。该插件使用$scope.selected = "Tutorial";
$scope.setTutorial = function(value) {
$scope.selected = value;
}
执行，但在插件执行后，eclipse在我的Activator中调用eclipsec.exe -consoleLog -console -noSplash -application headless.prefs.import preferences.epf方法，执行另一个插件中断：
堆栈跟踪:(前两行是我的插件退出）
stop()应该注意的是插件正在运行，而早些时候我得到了＃34;无法瞬态启动捆绑.. ..捆绑包的起始等级未达到＆＃34;。
有没有办法配置我的plugin.xml或激活器来尝试清除这些错误，或强制从Preferences Imported.
Importer exit.

方法退出eclipse？之后不需要调用任何其他东西这一点。
