，我就会收到此错误 compile 'org.elasticsearch.client:transport:5.0.0'
详细错误logcat：

PS：SO上已经有很多类似的帖子，但没有一个对我有帮助
有人可以帮我吗？另外，请告诉我解决这些问题的通用方法。
答案 0 :(得分：1)
在android部分添加以下代码
packagingOptions {
pickFirst 'META-INF/*'
}
答案 1 :(得分：0)
This github发行票据建议使用
packagingOptions {
pickFirst 'META-INF/INDEX.LIST'
pickFirst 'META-INF/LICENSE'
pickFirst 'META-INF/io.netty.versions.properties'
}

不建议直接在android应用程序中使用ElasticSearch。这样做的缺点是：
ElasticSearch实例REST API链接，并以您想要的方式使用indexes，甚至修改或删除它们。用户可以公开访问API链接。Android SDK dependencies和ElasticSearch依赖关系之间会存在此问题之间的依赖冲突。 更好的解决方法是，制作自己的API来处理ElasticSearch实例的请求。在App上，对该实例发出请求，该实例依次在您的ElasticSearch实例上发出请求。当有人点击您的API时，您可以获取搜索变量并构建您自己的查询。这种方法的优点是：
ElasticSearch链接可以是私有的，没有人可以删除您的索引。答案 3 :(得分：0)
别忘了放
packagingOptions {
pickFirst 'META-INF/*'
}
如果使用模块，则所有构建gradle文件。
