我的Eclipse RCP项目停止运行，我没有改变任何东西。我有两个运行配置，一个是.product，另一个是应用程序（两个都在问题发生之前运行）。
当我尝试运行.product配置时，构建终止而没有任何登录控制台（我试图运行调试器，但它在本机代码中的某处终止）。
当我尝试运行.application配置时，控制台中存在很多错误：

此处抛出了第一个错误日志的异常（但它不是LinkageError，只是Exception）：
try {
result = classInstance.newInstance();
} catch (Exception e) {
throwException(NLS.bind(RegistryMessages.plugin_instantiateClassError, contributingBundle.getSymbolicName(), className), e);
} catch (LinkageError e1) {
我试图删除： .metadata.plugins .metadata.plugins \ org.eclipse.e4.workbench \ workingsets.xml
但问题仍然存在
编辑：问题已解决。我启动了带有清除标记的应用程序（运行配置 - >主要（书签） - >工作区数据（区域） - >清除（标记）和错误消失）
