Maven签名解决方法

在config下的settings.xml文件中将mirrors改成如下：

<mirrors>
	  
	  
	  <!-- 中央仓库1 -->
	  <mirror>
	      <id>repo1</id>
	      <mirrorOf>central</mirrorOf>
	      <name>Human Readable Name for this Mirror.</name>
	      <url>http://repo1.maven.org/maven2/</url>
	  </mirror>
	  
	  <!-- 中央仓库2 -->
	  <mirror>
	      <id>repo2</id>
	      <mirrorOf>central</mirrorOf>
	      <name>Human Readable Name for this Mirror.</name>
	      <url>http://repo2.maven.org/maven2/</url>
	  </mirror>
    <!-- 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>
