MyEclipse启动server报错

2015-09-15 01:53:50

今天上班照常打开编译器，发现编译器报错了，但是代码区域没有报错，在server页面的错误信息为：Could not create the view: An unexpected exception was thrown。如下图

还有一系列的报错

java.lang.NullPointerException at com.genuitec.eclipse.ast.deploy.core.Deployment.<init>(Unknown Source) at com.genuitec.eclipse.ast.deploy.core.ModuleDeployment.<init>(Unknown Source) at com.genuitec.eclipse.ast.deploy.core.WebDeployment.<init>(Unknown Source) at com.genuitec.eclipse.ast.deploy.core.Deployment.create(Unknown Source) at com.genuitec.eclipse.ast.deploy.core.DeploymentManager.loadFromPreferences(Unknown Source) at com.genuitec.eclipse.ast.deploy.core.DeploymentManager.init(Unknown Source) at com.genuitec.eclipse.ast.deploy.core.DeploymentManager.<init>(Unknown Source) at com.genuitec.eclipse.ast.deploy.core.DeploymentManager.getDefault(Unknown Source) at com.genuitec.eclipse.ast.deploy.core.ui.ServerTreeViewer$ServerTreeContentProvider.inputChanged(Unknown Source) at org.eclipse.jface.viewers.ContentViewer.setInput(ContentViewer.java:276) at org.eclipse.jface.viewers.StructuredViewer.setInput(StructuredViewer.java:1690) at com.genuitec.eclipse.ast.deploy.core.ui.ServerTreeViewer.<init>(Unknown Source) at com.genuitec.eclipse.ast.deploy.core.ui.ServerView.createPartControl(Unknown Source) at org.eclipse.ui.internal.ViewReference.createPartHelper(ViewReference.java:375) at org.eclipse.ui.internal.ViewReference.createPart(ViewReference.java:229) at org.eclipse.ui.internal.WorkbenchPartReference.getPart(WorkbenchPartReference.java:595) at org.eclipse.ui.internal.PartPane.setVisible(PartPane.java:313)

仔细看下错误发现有一条 at com.genuitec.eclipse.ast.deploy.core.Deployment.这个错误，于是到工作空间下面的D:\Workspaces\.metadata\.plugins\org.eclipse.core.runtime\.settings目录下面找到了名称为at com.genuitec.eclipse.ast.deploy的prefs文件，打开文件一开，哈哈，原来里面都是原来的一些项目信息，怪不得会报java.lang.NullPointerException错误呢。果断将此文件删除，重启myeclipse10问题解决。
