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
原因是:本地设置的镜像仓库中没有对应的jar导致的
<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 中央仓库地址:
1. http://www.sonatype.org/nexus/
2. http://mvnrepository.com/ (本人推荐仓库)
3. http://repo1.maven.org/maven2
解决方法:
1.找到maven库目录,进入:~\.m2\repository\org\apache\maven\plugins\maven-compiler-plugin\3.1
2.若2.7.1目录下只有,"maven-compiler-plugin-3.1.pom.lastUpdated" 则需要到http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-compiler-plugin/3.1/,把里面的文件下载下来放到2.7.1,如果该仓库中没有,那么可以去http://search.maven.org/这个地方下载下来,然后放置到对应的本地仓库中
3.删除2.7.1下的maven-compiler-plugin-3.1.pom.lastUpdated文件。
4.项目右键-->maven-->Update Dependencies
如果以上方法还是无法解决该问题:
1.打开settings.xml,尝试换个mirror镜像或者干脆采用默认的仓库,即注释掉
