由于电脑突然死机，重启电脑后进入myeclipse的时候直接报
java.lang.NullPointerException

这玩意以前没见过，
com.genuitec.eclipse.ast.deploy.core.Deployment
百度了一下原来这个是myEclipse在workspace中生成的运行时的配置文件
.metadata\.plugins\org.eclipse.core.runtime\.settings
打开这个文件com.genuitec.eclipse.ast.deploy.core.prefs
eclipse.preferences.version=1
tomcat7Server.bpm.IEARProjectName=
tomcat7Server.bpm.altContextRoot=
tomcat7Server.bpm.contextRoot=/heas
tomcat7Server.bpm.deployIsOverProject=false
tomcat7Server.bpm.deploymentPath=D\:\\javaserver\\tomcat\\apache-tomcat-7.0.47\\webapps\\heas
tomcat7Server.bpm.isDeployed=true
tomcat7Server.bpm.isExploded=true
tomcat7Server.bpm.isUptoDate=true
tomcat7Server.bpm.noFileCopy=false
tomcat7Server.bpm.shouldBackup=false
tomcat7Server.bpm.shouldOverwrite=false
tomcat7Server.bpm.type=WebDeployment
tomcat7Server.pmreport.IEARProjectName=
tomcat7Server.pmreport.altContextRoot=
tomcat7Server.pmreport.contextRoot=/pmreport
tomcat7Server.pmreport.deployIsOverProject=false
tomcat7Server.pmreport.deploymentPath=D\:\\javaserver\\tomcat\\apache-tomcat-7.0.47\\webapps\\pmreport
tomcat7Server.pmreport.isDeployed=true
tomcat7Server.pmreport.isExploded=true
tomcat7Server.pmreport.isUptoDate=true
tomcat7Server.pmreport.noFileCopy=false
tomcat7Server.pmreport.shouldBackup=false
tomcat7Server.pmreport.shouldOverwrite=false
tomcat7Server.pmreport.type=WebDeployment
发现里面有两个项目，第一个项目我已经close掉了，由于突然死机，myeclipse没有把我close的项目从配置中去掉（估计是在关闭myeclipse的时候才会修改这些配置文件），把这个
tomcat7Server.bpm.
开头的配置去掉重启myEclipse就好了
