maven阿里倉庫配置和一個實際問題的解決

阿里倉庫配置

修改maven配置，如D:\apache-maven-3.6.0\conf\settings.xml

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository>D:\workspace123\2019\.m2\repository</localRepository>   

  <pluginGroups>
  </pluginGroups>

  <proxies>
  </proxies>

  <servers>
	<server>
      <id>alimaven</id>
    </server>	
  </servers>

  <mirrors>
	<mirror>
		<id>alimaven</id>
		<mirrorOf>*</mirrorOf>   
		<name>aliyun maven</name>
		<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
	</mirror>
  </mirrors>

  <profiles>
  </profiles>

</settings>

在引用json-lib的時候，從 https://mvnrepository.com/artifact/net.sf.json-lib/json-lib/2.4 複製的

        <!-- https://mvnrepository.com/artifact/net.sf.json-lib/json-lib -->
        <dependency>
            <groupId>net.sf.json-lib</groupId>
            <artifactId>json-lib</artifactId>
            <version>2.4</version>
        </dependency>

運行run as>mvn install會報錯：

Failure to find net.sf.json-lib:json-lib:jar:2.4 in http://maven.aliyun.com/nexus/content/groups/public/ was cached in the local repository, resolution will not be reattempted until the update interval of alimaven has elapsed or updates are forced -> [Help 1]

在線瀏覽阿里倉庫(可以找到各種jar和源碼jar) https://maven.aliyun.com/mvn/view 找到相應jar的依賴，發現多了一行<classifier>jdk15</classifier>，完整的如下：

		<dependency>
			<groupId>net.sf.json-lib</groupId>
			<artifactId>json-lib</artifactId>
			<version>2.4</version>
			<!-- https://maven.aliyun.com/mvn/view的central的 /net/sf/json-lib/json-lib/2.4/json-lib-2.4-jdk15.jar -->
			<classifier>jdk15</classifier>
		</dependency>
