您好，我正在面对错误消息，而eclipse正在验证项目。我试图清理该项目，但它根本没用。
此外，我已经从eclipse.ini文件增加了堆大小，但仍然得到相同的错误。 eclipse.ini文件下面是：
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20150204-1316
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
2048M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
2048m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Xms1G
-Xmx3G
我也检查了来自.metadata\.logs的日志，好像我在某个地方遇到了僵局。就是这样。

有人可以告诉我如何解除僵局？这样我就可以继续前进了。因为没有验证项目，工作空间就无法正常构建。帮助将不胜感激。
