今天新建了一个maven项目，因为是通过公司的工具新建的，代码拉下来就有src、pom.xml文件。

导入Eclipse却报空指针异常。具体如下：

An error has occurred. See error log for more details.
java.lang.NullPointerException

一时没看明白是为什么，搜了一下Eclipse的日志文件。

日志在workSpace的.metadata里的.log文件。

点开查看，如下：

搜了一圈，说是Eclipse的插件问题导致的，可以把“.metadata”这个文件夹删掉，代价是项目需要重新导入。

我删了，依然不行。

另外，不仅项目项目需要重新导入，Eclipse配置也全部还原了。

无计可施的时候，我对比了一下之前的文件，发现pom.xml里少配了一些东西。

<project xmlns="http://maven.apache.org/POM/4.0.0"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <modelVersion>4.0.0</modelVersion>

  <properties>
  ……

正常的项目这部分是下面这样的：

<project xmlns="http://maven.apache.org/POM/4.0.0"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <modelVersion>4.0.0</modelVersion>

    <groupId>com.shuimutong</groupId>

    <artifactId>testw</artifactId>

    <packaging>war</packaging>

    <version>0.0.1-SNAPSHOT</version>

    <name>testwMavenWebapp</name>

    <url>http://maven.apache.org</url>

  <properties>
  ……

把配置补全，导入成功！
