这篇文章主要介绍了解决MyEclipse10.7部署报错抛空指针异常问题的方法，需要的朋友可以参考下

先对问题进行描述：

（1）在MyEclipse Servers视图在MyEclipse 10.7.0在某些情况下，可能无法打开。试图打开视图将导致NPE将被记录。

Could not create the view: An unexpected exception was thrown.

如下所示：

（2）如果出现了上述的错误按照如下的3个步骤解决：
1、首先关闭MyEclipse工作空间。

2、然后删除工作空间下的 “/.metadata/.plugins/org.eclipse.core.runtime/.settings/com.genuitec.eclipse.ast.deploy.core.prefs”

这个文件。在这个文件中存储了一些部署项目的信息。删了这个部署的项目的信息就没有错误了。

3、重启启动MyEclipse即可解决了。可爱的猫猫又出现了！

以上就是关于MyEclipse10.7部署报错的解决方案，希望对大家的学习有所帮助。
