我使用corda 4.5，gradle插件版本为5.0.10，postgres作为我的数据库。当我尝试运行deployNodes任务时，出现以下错误：

[ERROR] 15:51:47+0530 [main] internal.NodeStartupLogging. - Could not find the database driver class. Please add it to the drivers directory. [Error Code: database-missing-driver For further information, please go to https://docs.corda.net/docs/corda-os/4.5/error-codes.html] - Could not find the database driver class. Please add it to the 'drivers' folder. [errorCode=1oswgkz, moreInformationAt=https://errors.corda.net/OS/4.5/1oswgkz]

以下是build.gradle文件中的deployNode任务代码：

    task deployNodes(type: net.corda.plugins.Cordform, dependsOn: ['jar']) {
    nodeDefaults {
        projectCordapp {
            deploy = false
        }
        cordapp "$confidential_id_release_group:ci-workflows:$confidential_id_release_version"
        cordapp "$accounts_release_group:accounts-contracts:$accounts_release_version"
        cordapp "$accounts_release_group:accounts-workflows:$accounts_release_version"

        cordapp project(':cordapp-contracts-states')
        cordapp project(':workflows')
