java - nodeBuilder()/NodeBuilder - 无法解析符号 - Elastic Search Java API(在 Android 上)

Question

我添加了 Gradle 依赖项，compile 'org.elasticsearch.client:transport:5.2.1'。

我在同步 Gradle 构建时收到警告列表。

Warning:WARNING: Dependency commons-logging:commons-logging:1.1.3 is ignored for release as it may be conflicting with the internal version provided by Android.
Warning:WARNING: Dependency org.apache.httpcomponents:httpclient:4.5.2 is ignored for release as it may be conflicting with the internal version provided by Android.

但是 Gradle 构建成功了。现在我在 nodeBuilder() 或 NodeBuilder 处收到错误。错误是:无法解析符号。我该如何解决这个问题？

ElasticSearch 托管在 Maven 中心。在您的 Maven 项目中，您可以在 pom.xml 文件中定义要使用的 ElasticSearch 版本，如下所示:

<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch</artifactId>
    <version>0.90.3</version>
</dependency>

Android Studio 不使用 Maven 作为其构建器；它改用 Gradle。所以尝试添加这个依赖:

dependencies {
    ...
    compile 'org.elasticsearch:elasticsearch:0.90.3'
}
