Eclipse无法启动报An internal error occurred during: ＂reload maven project＂. java.lang.NullPointerException

myecplise上将工程部署到应用下时，经常出现 An internal error occurred during: "Add Deployment". java.lang.NullPointException 错误。很让人郁闷。
究其原因，一般是因为项目从别处导入的，从cvs上down下来的等。
原因一、jdk版本不一致。具体步骤如下：
右键项目名→Properties→Java Build Path→Libraries→选中JRE System Library[Sun JDK 1.6.0_13]→Edit→选中“Workspace default JRE(Sun JDK 1.6.0_13)”→Finish
以上是以你本地JDK版本为主
原因二，也是出问题最频繁的地方：工程下的.mymetadata文件内容与原项目不一致。这里可能有<project-module 中缺少context-root 属性设置，也可能<attribute 中value属性值不对。所以需要原项目的配置文件对照一下。或者尝试着给value设置不同值，每次设置修改后，需要重启myeclipse。value的值大概有WebRoot，webapp，<prjroot> 等
给一个配置示例：
<?xml version="1.0" encoding="UTF-8"?>
<project-module
type="WEB"
name="COA"
id="myeclipse.1291700036453"
j2ee-spec="1.4"
context-root="/COA"
archive="CRM.war">
<attributes>
<attribute name="webrootdir" value="<prjroot>" />
</attributes>
</project-module>
由于没有正常关机导致eclipse无法将数据正常写入配置文件导致无法启动。报这样一个异常
An internal error occurred during: "reload maven project". java.lang.NullPointerException
查看workspace/.metadata/.log发现如下异常：

网上查了下说删除.metadata目录后重新导入项目即可，尝试了一下确实可行。但由于项目较多而且很多配置项需要重新配，这种情况下只好另觅道路了。既然删除.metada可以正常启动，如此可以推断只要将异常的项目从.metadata中移除即可。于是通过everything快速找到相应工程的文件将其一一删除，重启后还是不行。
于是通过sublime搜索.metadata下包含“maentest”的文件，并将相应的配置项一一删除。最后发现是eclipse加载界面配置文件workbench.xmi中的sharedElements配置项找不到相应的文件导致的异常。于是将对应的sharedElements删除，再次重启。妥妥的。
找到相应的sharedElements将其删除
