这是我第一次在grails应用程序中使用ES Java API客户端。我在这里遵循指示：https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/current/installation.html
一切都安装正确，包被识别。
作为Bootstrap.groovy的一部分，我试图确保索引存在。

Bootstrap.groovy

class BootStrap {

    JobSchedulerService jobSchedulerService
    ProjectSearchService projectSearchService

    def init = { servletContext ->
        jobSchedulerService.startup()
        projectSearchService.createIndex()
    }

    def destroy = {
        jobSchedulerService.shutdown()
    }
}

其中createIndex在ProjectSearchService内的表达式如下：

class ProjectSearchService {

    ElasticSearchClientProviderService elasticSearchClientProviderService

    void createIndex() {
        ElasticsearchIndicesClient elasticsearchIndicesClient =
            elasticSearchClientProviderService.getClient().indices()

        boolean exists = elasticsearchIndicesClient.exists({ c ->
            c.index("projects")
        }).value()

        if (!exists) {
            elasticsearchIndicesClient.create({ c ->
                c.index("projects")
            })
        }
    }
}

其中elasticSearchClientProviderService.getClient()为：

class ElasticSearchClientProviderService {

    ElasticsearchClient client

    ElasticsearchClient getClient() {
        if (!client) {
            // Create the low-level client
            RestClient restClient = RestClient.builder(
                new HttpHost("localhost", 9200)).build();

            // Create the transport with a Jackson mapper
            ElasticsearchTransport transport = new RestClientTransport(
                restClient, new JacksonJsonpMapper());

            // And create the API client
            client = new ElasticsearchClient(transport);
        }

        client
    }
}

一切都很简单，但当我试图运行应用程序时，我得到以下错误：

根据这一原因：Caused by: java.lang.NoClassDefFoundError: Could not initialize class com.fasterxml.jackson.databind.ObjectMapper类在那里（至少我可以手动找到它）。
在我的build.gradle中，我有两个相关的依赖项：

compile 'co.elastic.clients:elasticsearch-java:7.16.2'
    compile 'com.fasterxml.jackson.core:jackson-databind:2.12.3'

下面是gradle dependencies的输出：

似乎一切都准备就绪了。我错过了什么？
