要注意的地方
settings.xml檔案可能存在兩個位置：
Maven預設： ${maven.home}/conf/settings.xml
使用者目錄下： ${user.home}/.m2/settings.xml
如果兩個檔案都存在，重複覆蓋，其中以使用者settings.xml為主，優先。
如果使用私鑰登入到伺服器，請確保省password。否則，金鑰將被忽略。

maven映象
id，name：此映象的唯一識別符號和使用者友好名稱。
在id用於區分mirror，並從所述挑選相應的證書連線到反射鏡時部。
url：此映象的基本URL。構建系統將使用此URL連線到儲存庫，而不是原始儲存庫URL。
mirrorOf：指定儲存庫。 中央倉庫central。

構建編譯配置

指定使用環境

  <activation>
        <property>
          <name>target-env</name>
          <value>dev</value>
        </property>
      </activation>

匹配jdk版本

   <id>jdk-1.4</id>

      <activation>
        <jdk>1.4</jdk>
      </activation>

啟用環境，沒有找到就使用預設的

  <activeProfiles>
    <activeProfile>alwaysActiveProfile</activeProfile>
    <activeProfile>anotherAlwaysActiveProfile</activeProfile>
  </activeProfiles>

儲存庫

簡單說就是映象網站下，專案分類目錄，類如https://repo1.maven.org/maven2/HTTPClient/

updatePolicy：此元素指定應該嘗試進行更新的頻率。Maven會將本地POM的時間戳（儲存在儲存庫的maven-metadata檔案中）與遠端進行比較。選項包括：always，daily（預設），interval:X（其中X是分鐘內的整數）或never。
checksumPolicy：當Maven將檔案部署到儲存庫時，它還將部署相應的校驗和檔案。你的選擇是ignore，fail或者warn在丟失或不正確的校驗。
佈局：在以上對儲存庫的描述中，提到它們都遵循相同的佈局。這基本上是正確的。Maven 2的儲存庫具有預設佈局。但是，Maven
1.x具有不同的佈局。使用此元素可以指定是default還是legacy。
