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:Javam2 epository</localRepository> </settings>
可见，本地的Maven库存放位置为:D:Javam2 epository,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：

提交成功后的dubbo控制台效果如下：
6. web.xml中配置注意事项：
7. 打成war包要注意check Maven依赖是否被成功的加入到了打包路径，在Deployment Assembly中设置：
8. 在Mavne pom.xml文件中指定JDK版本：
9. 在maven pom.xml文件中指定多个地址：
在show view中找到maven,可以看到工程maven库的情况：
10. 更新整个工程，让maven重新check Pom文件，类似于idea intellij中 maven reimport:
11. 在执行run –> mvn compile/install/clean出现找不到M2_HOME的情况，解决方案如下：
在JDK中添加默认参数-Dmaven.multiModuleProjectDirectory=M2_HOME(前提是操作系统中设置了M2_HOME的环境变量，注意windows系统中，M2_HOME前面不能够添加$符号，在linux系统中必须要添加$符号）
