问题

安装aspose一直失败，原因是aspose文件不在公共仓库中

<dependency>
    <groupId>com.aspose</groupId>
    <artifactId>aspose-pdf</artifactId>
    <version>21.11</version>
</dependency>

配置文件如下

<mirror>
  <id>aliyunmaven</id>
  <mirrorOf>*,!pomres</mirrorOf>
  <name>aliyun maven</name>
  <url>https://maven.aliyun.com/repository/central</url>
</mirror>
<mirror>
  <id>pomres</id>
  <mirrorOf>public</mirrorOf>
  <name>aspose</name>
  <url>https://releases.aspose.com/java/repo</url>
</mirror>

修改pom.xml

<repositories>
     <repository>
         <id>maven</id>
         <url>https://repo1.maven.org/maven2</url>
     </repository>
    <repository>
        <id>pomres</id>
        <url>https://releases.aspose.com/java/repo</url>
    </repository>
</repositories>

执行mvn compile -X安装包

如果修改了配置文件还是报错需要看C:\Users\16471\.m2下是否有settings.xml需要修改它，而不是maven安装包conf下的settings.xml

保持一致
