我是靠谱客的博主眼睛大水杯，最近开发中收集的这篇文章主要介绍Maven安装成功后，总是无法成功mvn install？解决方法是JDK设置的问题。，觉得挺不错的，现在分享给大家，希望可以做个参考。

我重新执行mvn install，直接报错

这个问题怎么都无法解决，重新在eclipse和myeclipse中重新配置JDK路径还是无法解决。

不知道是不是和我最开始嫌弃maven下载太慢，在maven目录中修改了setting.xml下载路径，换成aliyun端口。虽然貌似前几次下载依旧不成功，我反复尝试mvn install，结果就杯具了。。。。

-----------------------------------------------------分割线---------------------------------------------------------------

出现这个而问题之后我改变了一个思路来做，我重新设置了maven的本地仓库地址，把默认到C:Usershasee.m2repository的地址改成了我自己设置的地址：D:Mavenm2m2repository；具体的修改方法看这两个引用链接：

http://www.cnblogs.com/liunanjava/archive/2015/11/05/4936037.html 或者http://xiaocao000.iteye.com/blog/1758639 这两篇博主的文章都可以，也许觉得不够详细，那么可以再参考百度问答的一个链接：https://zhidao.baidu.com/question/1769645808405821420.html

言归正传，这次我修改了本地仓库地址后，重新到项目文件下用控制台输入mvn install这次就没有报之前的错误，报出了一个新错误：

没有想到竟然还是会报错。。。。。。。。。

修改maven目录conj下的setting.xml文件和本地仓库下的setting.xml文件中的：

<profiles>
    <!-- profile
     | Specifies a set of introductions to the build process, to be activated using one or more of the
     | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>
     | or the command line, profiles have to have an ID that is unique.
     |
     | An encouraged best practice for profile identification is to use a consistent naming convention
     | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.
     | This will make it more intuitive to understand what the set of introduced profiles is attempting
     | to accomplish, particularly when you only have a list of profile id's for debug.
     |
     | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.
    <profile>
      <id>jdk-1.8</id>

      <activation>
        <jdk>1.8</jdk>
      </activation>

      <repositories>
        <repository>
          <id>jdk18</id>
          <name>Repository for JDK 1.8 builds</name>
          <url>http://www.myhost.com/maven/jdk18</url>
          <layout>default</layout>
          <snapshotPolicy>always</snapshotPolicy>
        </repository>
      </repositories>
    </profile>

把其中的JDK版本全部修改成自己本机的JDK版本，不知道的可以控制台Java -version查看

修改完成之后我就把我的本机本地仓库中的maven下载清空，控制台到项目根目录直接mvn install，现在重新下载中：

希望这次可以成功啊

----------------------------------

这次果然成功了！！！
