eclipse创建maven工程问题总结

一、在eclipse导入maven工程或创建maven工程时，会出现以下错误：

Failure to transfer org.apache.maven.plugins:maven-compiler-plugin:pom:3.1 from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be 
 reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven.plugins:maven-compiler-plugin:pom:3.1 
 from/to central (https://repo.maven.apache.org/maven2): sun.security.validator.ValidatorException: PKIX path building failed: 

 sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Multiple annotations found at this line:
- CoreException: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-compiler-plugin:3.1 or one of its dependencies could not be resolved: Failed to read 
artifact descriptor for org.apache.maven.plugins:maven-compiler-plugin:jar:3.1: ArtifactResolutionException: Failure to transfer org.apache.maven.plugins:maven-compiler-plugin:pom:

- Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (execution: default-compile, phase: compile)

以上基本上是由于网络问题导致连接不到中央库引起。

解决办法1：在pom.xml增加如下配置，替换默认的编译配置

 
       
       maven-compiler-plugin
       3.3
       
         
           default-compile
           compile
           
             compile
           
           
             1.8
             1.8
             UTF-8
           
         
         
           default-testCompile
           test-compile
           
             testCompile
           
           
             1.8
             1.8
             UTF-8
           
         
       
       
         1.8
         1.8
         UTF-8
       
     
     

解决方法2：替换仓库位置

修改maven配置文件setting.xml，使用阿里云的镜像

   
alimaven    
aliyun maven    
http://maven.aliyun.com/nexus/content/groups/public/    
central            

修改以上配置后，点击工程右键--Maven--Update Project刷新工程。
