    MyEclipse Server view报错解决方法
  4.  

    Server视图显示的是项目部署在Server的情况,每个工作空间都有个性化配置。找到工作空间的Server项目部署配置文件。

    --------------------------------------------------------------------------------

    目录是$工作空间\.metadata\.plugins\org.eclipse.core.runtime\.settings\com.genuitec.eclipse.ast.deploy.core.prefs

    MyEclipse Server view报错解决方法
  5.  

    根据工作空间的Server项目部署配置文件可以看出,Server部署了两个项目,分别是SeNT-DL,SeNT-b11M

    --------------------------------------------------------------------------------

    eclipse.preferences.version=1

    tomcat7Server.SeNT-DL.IEARProjectName=

    tomcat7Server.SeNT-DL.altContextRoot=

    tomcat7Server.SeNT-DL.contextRoot=/SeNT-DL

    tomcat7Server.SeNT-DL.deployIsOverProject=false

    tomcat7Server.SeNT-DL.deploymentPath=F\:\\apache-tomcat-7.0.55\\webapps\\SeNT-DL

    tomcat7Server.SeNT-DL.isDeployed=true

    tomcat7Server.SeNT-DL.isExploded=true

    tomcat7Server.SeNT-DL.isUptoDate=true

    tomcat7Server.SeNT-DL.noFileCopy=false

    tomcat7Server.SeNT-DL.shouldBackup=false

    tomcat7Server.SeNT-DL.shouldOverwrite=false

    tomcat7Server.SeNT-DL.type=WebDeployment

    tomcat7Server.SeNT-b11M.IEARProjectName=

    tomcat7Server.SeNT-b11M.altContextRoot=

    tomcat7Server.SeNT-b11M.contextRoot=/SeNT-b11M

    tomcat7Server.SeNT-b11M.deployIsOverProject=false

    tomcat7Server.SeNT-b11M.deploymentPath=F\:\\apache-tomcat-7.0.55\\webapps\\SeNT-b11M

    tomcat7Server.SeNT-b11M.isDeployed=true

    tomcat7Server.SeNT-b11M.isExploded=true

    tomcat7Server.SeNT-b11M.isUptoDate=true

    tomcat7Server.SeNT-b11M.noFileCopy=false

    tomcat7Server.SeNT-b11M.shouldBackup=false

    tomcat7Server.SeNT-b11M.shouldOverwrite=false

    tomcat7Server.SeNT-b11M.type=WebDeployment

    实际上,Server只部署了一个项目SeNT-DL,另外一个项目SeNT-b11M被删除了。

  7.  

    另外一个项目SeNT-b11M被删除了,删除的方式是进入tomcat的webapps,直接删除。没有通知MyEclipse,导致MyEclipse的工作空间的Server项目部署配置文件没有做更新,依旧配置Server部署了两个项目,分别是SeNT-DL,SeNT-b11M。

  8.  

    解决方法一:更新MyEclipse的工作空间的Server项目部署配置文件com.genuitec.eclipse.ast.deploy.core.prefs,根据实际情况,删除已经不存在于Server的项目配置。把以下高亮部分配置删除。

  9.  

    解决方法二:删除tomcat的webapps的所有项目,删除文件com.genuitec.eclipse.ast.deploy.core.prefs。这种方式相当于清空部署在tomcat的所有项目,清空MyEclipse的工作空间的Server项目部署配置文件。(本人使用的就是这一种方法 ,直接删除)

    MyEclipse Server view报错解决方法
  10.  

    为了避免此类问题再次出现,想要删除部署在tomcat的项目时,不要进入tomcat的webapps,直接删除,而是在server view视图做删除。在server view视图做删除项目时,MyEclipse会更新工作空间的Server项目部署配置文件。
