今天学习maven,在控制台下新建maven项目没有问题,但是在STS(eclipse)下创建maven项目老是报错,郁闷死了:
----------------------------------------------------
错误信息:Could not resolve archetype org.apache.maven.archetypes:maven-archetype-webapp:RELEASE from any of the configured repositories.
Could not resolve artifact
Failed to resolve version for org.apache.maven.archetypes:maven-archetype-webapp:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype-webapp/maven-metadata.xml in local (F:\maven\repository)
Failed to resolve version for org.apache.maven.archetypes:maven-archetype-webapp:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype-webapp/maven-metadata.xml in local (F:\maven\repository)
----------------------------------------------------
遇到问题,就是baidu/google查找解决方法,可惜网上很多人提到的方法试了都不行,郁闷了好几个小时,最后找到问题原因如下:
以上报错的原因是:在settings.xml 文件中 mirrors出了问题。默认maven3.1.0安装目录下的conf目录下的setting.xml配置文件中的mirrors配置是这样的:
<mirrors> <!-- mirror | Specifies a repository mirror site to use instead of a given repository. The repository that | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used | for inheritance and direct lookup purposes, and must be unique across the set of mirrors. | <mirror> <id>mirrorId</id> <mirrorOf>repositoryId</mirrorOf> <name>Human Readable Name for this Mirror.</name> <url>http://my.repository.com/repo/path</url> </mirror> --> </mirrors>
我也不是很清楚为什么就是不行(猜测是maven默认的internet仓库里的文件不全,所以就添加了大家用得最多的maven的internet仓库之一:lbiblio,基本所有的开源的框架的jar文件都有提供),然后在setting.xml配置文件上面我添加了一个新的mirror,添加后如下:
<mirrors> <!-- mirror | Specifies a repository mirror site to use instead of a given repository. The repository that | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used | for inheritance and direct lookup purposes, and must be unique across the set of mirrors. | <mirror> <id>mirrorId</id> <mirrorOf>repositoryId</mirrorOf> <name>Human Readable Name for this Mirror.</name> <url>http://my.repository.com/repo/path</url> </mirror> --> <!--以下是新增加上去的--> <mirror> <id>ibiblio.org</id> <name>ibiblio Mirror of http://repo1.maven.org/maven2/</name> <url>http://mirrors.ibiblio.org/pub/mirrors/maven2</url> <mirrorOf>central</mirrorOf> </mirror> </mirrors>
就只是修改了setting.xml配置文件上的这个地方,然后在控制台下我重新输入:
mvn help:system
回车,就可以看到重新下载了好多的jar包文件。
等下载完成后,再在eclipse新建maven项目就正常了。
