搭建Dubbo+Myeclipse2015+Maven3.3.1的过程遇到问题集锦

1. 找不到dubbo2.8.4包的问题

在编译Maven工程的过程中，出现如下问题：

Description Resource Path Location Type
ArtifactDescriptorException: Failed to read artifact descriptor for com.alibaba:dubbo:jar:2.8.4: UnresolvableModelException: Failure to find com.alibaba:dubbo-parent:pom:2.8.4 in http://172.28.3.60:8081/nexus/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of thirdparty has elapsed or updates are forced pom.xml /FileIO line 1 Maven Dependency Problem

本地Maven的配置如下：settings.xml:

<settings 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/settings-1.0.0.xsd">  
 <mirrors>
    <mirror>
      <id>CN</id>
      <name>OSChina Central</name>                                                                                                                       
      <url>http://maven.oschina.net/content/groups/public/</url>
      <mirrorOf>central</mirrorOf>
    </mirror>
  </mirrors>
  
  <localRepository>D:\Java\m2\repository</localRepository>
</settings>

可见，本地的Maven库存放位置为:D:\Java\m2\repository,在这个目录下，有如下结构（正常情况下，异常情况下是没有这个结果的，而且dubbo2.8.4这个版本没有公开发布到maven中心库，需要自己进行编译，编译成功后，就可以得到如下的文件结构）：

编译过程：1.从github上将大猫download下来，下载地址：https://github.com/dangdangdotcom/dubbox

下载下来后，解压，在解压后的路径中，执行: mvn install -Dmaven.test.skip=true

执行完毕后，就可以生成本地maven库中dubbo的目录结构，这样工程中所有使用dubbo2.8.4的地方，都可以正常的编译：

2. 用Maven构建web工程，出现如下错误：

Description    Resource    Path    Location    Type
The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path    index.jsp    /web Maven Webapp/src/main/webapp    line 1    JSP Problem

这个错误是因为没有导入web工程的运行时环境导致的，解决办法如下：

然后将project clean后，重新构建，错误自动消失。

3. 修改项目的JDK版本，有时会出现MyEclipse打出的war包，部署到Tomcat服务器上不能够使用的情况，错误一般如下，对于这种情况，要认真检查项目使用JDK版本，以及服务器运行时的JDK版本，只要匹配就不会有问题。

Unsupported major.minor version 52.0 (unable to load class：
What it means is that , your code is compiled with different version of java to java version which is running it . make sure you compile and runt it with the same version if java.

4. Maven POM中添加的 Spring版本和Myeclipse提供的Spring版本中出现冲突，解决办法是将Myeclipse中自带的Spring 4.1从Build中移除掉：
