MyEclipse 启动时报错:'Building workspace' has encountered a problem解决方法

MyEclipse工作空间有时候会报错如下:'Building workspace' has encountered a problem. Errors occurred during the build.并且详细信息为:Errors occurred during the build.
Errors running builder 'DeploymentBuilder' on project 'bos'.
java.lang.NullPointerException 意思是说在部署XXX工程时出现了空指针,

      图片如下:

以前我一般都是重新建工作空间,但这样所有的设置都要重新导入,现有一方法百试不爽:到工作空间所在文件夹下:D:\Workspaces\MyEclipse 10\.metadata\.plugins\org.eclipse.core.runtime\.settings\下面删除文件     com.genuitec.eclipse.ast.deploy.core.prefs之后再重启Myeclipse即可。
