有人可以帮我解决以下问题。我已经搜索了整个群组。我找到了一些链接，但没有帮助我解决问题。
我们最近将Java和Rundeck升级到了最新版本。
遵循本文档https://rundeck.org/docs/upgrading/upgrade-to-rundeck-3.x.html
使用yum进行升级。在一段时间后，我注意到service.log
中出现了许多错误，Rundeck URL通过SSL可以很好地加载com.amazonaws.SdkClientException: Unable to execute HTTP request: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
at com.amazonaws.http.AmazonHttpClient$RequestExecutor.handleRetryableException(AmazonHttpClient.java:1069)
at com.amazonaws.http.AmazonHttpClient$RequestExecutor.executeHelper(AmazonHttpClient.java:1035)

因此，我已按照本文档https://rundeck.org/docs/administration/security/configuring-ssl.html
我从ps命令rundeck看到指向正确的信任库文件，这里是完整的过程命令
