   <dependency>
            <groupId>com.aspose</groupId>
            <artifactId>aspose-words</artifactId>
            <version>15.8.0</version>

可以加入本地仓库

mvn install:install-file -DgroupId=com.aspose -DartifactId=aspose-words -Dversion=15.8.0 -Dpackaging=jar -Dfile=aspose-words-15.8.0-jdk16.jar

在项目静态资源路径下添加一个license.xml文件，不然生成的pdf会有水印
