CoreException: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-compiler-plugin

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: Failure to find org.apache.maven.plugins:maven-compiler-plugin:jar:3.1 in http://repository.jboss.org/nexus/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of jboss-public-repository-group has elapsed or updates are forced

緣由是：本地設置的鏡像倉庫中沒有對應的jar致使的

<mirrors>  
    <mirror>
         <id>jboss-public-repository-group</id>
         <mirrorOf>central</mirrorOf>
         <name>JBoss Public Repository Group</name>
         <url>http://repository.jboss.org/nexus/content/groups/public</url>
    </mirror>
  </mirrors>

 Maven 中央倉庫地址：

1. http://www.sonatype.org/nexus/

2. http://mvnrepository.com/ （本人推薦倉庫）

3. http://repo1.maven.org/maven2

解決方法：

1.找到maven庫目錄，進入：~\.m2\repository\org\apache\maven\plugins\maven-compiler-plugin\3.1

2.若2.7.1目錄下只有，"maven-compiler-plugin-3.1.pom.lastUpdated" 則須要到http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-compiler-plugin/3.1/，把裏面的文件下載下來放到2.7.1，若是該倉庫中沒有，那麼能夠去http://search.maven.org/這個地方下載下來，而後放置到對應的本地倉庫中

3.刪除2.7.1下的maven-compiler-plugin-3.1.pom.lastUpdated文件。

4.項目右鍵-->maven-->Update Dependencies

 

若是以上方法仍是沒法解決該問題：

1.打開settings.xml，嘗試換個mirror鏡像或者乾脆採用默認的倉庫,即註釋掉
