问题内容
我正在开发一个要在应用程序中上传的 jar 文件，该应用程序将利用它连接到 azure 密钥保管库并检索凭据以进一步在服务器上运行一些操作。我正在使用 maven，并陷入此错误：
java.lang.noclassdeffounderror: reactor/netty/transport/clienttransport
at java.base/java.lang.classloader.defineclass1(native method)
这是代码部分：
clientcertificatecredential clientcertificatecredential = new clientcertificatecredentialbuilder()
.tenantid(tenantid)
.clientid(clientid)
.pfxcertificate(certificatepath, certificatepassword)
.build();
secretclient secretclient = new secretclientbuilder()
.vaulturl(keyvaulturl)
.credential(clientcertificatecredential)
.buildclient();
我已经尝试了相当多版本的依赖项，但仍然无法解决它，因为我是新手。现在已经坚持了几天了。依赖部分如下所示：
com.azure
azure-identity
1.7.0
com.azure
azure-security-keyvault-secrets
4.2.3
io.projectreactor
reactor-core
3.4.10
io.projectreactor.netty
reactor-netty
1.0.11
我已经尝试过几个版本的依赖项，但我对此很陌生，无法弄清楚。
更新： 我在 pom 文件中添加了 azure bom，但错误仍然略有变化：

正确答案
我已经能够通过从 azure 依赖项（azure-identity 和 azure-security-keyvault-secrets）中排除 azure-core-http-netty 并添加 azure-core-http-okhttp 工件来解决该错误。
