解决：[ERROR] Error executing Maven. [ERROR] 1 problem was encountered while building the effective set
我出现这个问题的原因是因为maven文件目录下得conf文件下得settings.xml文件配置出现问题，我在添加中心仓库的时候添加的字段中，注释括号出现了问题：

这里是正确的配置代码：
<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.
     |
     -->

<!-- 阿里云仓库 -->
<mirror>
    <id>alimaven</id>
    <mirrorOf>central</mirrorOf>
    <name>aliyun maven</name>
    <url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
</mirror>

<!-- *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>

<!-- *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>
      <id>mirrorId</id>
      <mirrorOf>repositoryId</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>
      <url>http://my.repository.com/repo/path</url>
    </mirror>
  </mirrors>

注释位置添加错误，代码一中的–>应该填在代码二中：

代码一：
</mirror>
  -->
  </mirrors>

代码二：
unique across the set of mirrors.
     |
     -->

<!-- 阿里云仓库 -->
<mirror>

总之就是添加仓库路劲时把<mirror></mirror>添加到了一个<!-- -->之中，导致系统无法识别被注释的内容究竟是哪一块儿，所以报错。
