由于异常加载系统包，Eclipse（STS）在更新后无法启动

Question

我今天收到了Eclipse的更新（STS版本3.3.0）。更新需要eclipse重新启动，但Eclipse仍然无法启动。检查GUI的错误消息中提到的日志文件后，我发现了这个：

Answer 1

经过几个小时的挖掘后，我发现我的插件目录中有多个org.eclipse.osgi_XXXXXXXXXXXXXXX.jar个文件。我删除了org.eclipse.osgi_3.9.1.v20130814-1242.jar（之前是我最近的那个），并且保留了org.eclipse.osgi_3.9.1.v20140110-1610.jar，因为版本号与堆栈跟踪中提到的版本号相匹配。之后，Eclipse似乎正常启动。
