我是solr的新手，如果我在这里遗漏了什么，请告诉我。我正在按照此指南操作，但目前还没有成功-https://solr.apache.org/guide/8_10/making-and-restoring-backups.html
我现在在solr.xml中添加了一个备份部分

<backup>
    <repository name="s3" class="org.apache.solr.s3.S3BackupRepository" default="false">
      <str name="s3.bucket.name">solr-backups</str>
      <str name="s3.region">us-east-1</str>
    </repository>
  </backup>

之后，我添加了S3插件（通过ansible，就像我通常做的那样）

- name: Copy SOLR S3 module to server
  copy:
    src: /opt/solr/dist/solr-s3-repository-8.10.1.jar
    dest: /opt/solr/server/solr/lib
    owner: solr
    group: solr
    remote_src: yes
  become_user: root

最后，在solr配置中添加了S3凭据

- name: Add aws credentials
  become_user: root
  lineinfile:
    path: /opt/solr/bin/solr.in.sh
    line: 'SOLR_OPTS="-Daws.accessKeyId=REDACTED -Daws.secretAccessKey=REDACTED"'

在重新启动Solr以应用所有新设置后，我将运行以下命令进行备份。

http://my-server.com:8983/solr/schools/replication?command=backup&name=29-10-2021&repository=s3&location=backupfolder

但接收到如下错误：

HTTP ERROR 500 java.lang.NoClassDefFoundError: org/apache/solr/core/backup/repository/BackupRepository

你知道我的配置出了什么问题吗？
