英文:
ElasticSearch ClassCastException - MappingMetadata to MappingMetadata
问题
以下是翻译好的部分：
我需要你的帮助。我不知道这里出了什么问题。
当我启动我的JavaApp从ElasticSearch获取数据时，我遇到了这个ClassCastException：
ElasticDBPersistanceImp | findQueryField failed for templateId
java.lang.ClassCastException: org.elasticsearch.cluster.metadata.MappingMetadata cannot be cast to org.elasticsearch.cluster.metadata.MappingMetaData
at com.initka.bprocess.hforms_formlist.persistance.impl.elastic.ElasticDBPersistanceImpl.getAllFields(ElasticDBPersistanceImpl.java:251) ~[classes/:?]
at com.initka.bprocess.hforms_formlist.persistance.impl.elastic.ElasticDBPersistanceImpl.findQueryField(ElasticDBPersistanceImpl.java:226) ~[classes/:?]

at java.lang.Thread.run(Thread.java:748) [?:1.8.0_222]
我正在使用的代码在这里提供：https://www.elastic.co/guide/en/elasticsearch/client/java-rest/master/java-rest-high-get-mappings.html
所以稍微修改一下，它看起来像这样：
GetMappingsResponse mapping1 = dbManager.getFormlistDBConnection().indices().getMapping(getMappingsRequest, RequestOptions.DEFAULT);
Map<String, MappingMetaData> mappings2 = mapping1.mappings();
MappingMetaData mappingMetaData = mappings2.get(indexName);
Map<String, Object> sourceAsMap = mappingMetaData.getSourceAsMap();
所以也许你们中的某些人知道这里出了什么问题吗？
提前感谢。

The code I'm using is provided at the Docs here https://www.elastic.co/guide/en/elasticsearch/client/java-rest/master/java-rest-high-get-mappings.html
So with a little bit of modification it looks like:
GetMappingsResponse mapping1 = dbManager.getFormlistDBConnection().indices().getMapping(getMappingsRequest, RequestOptions.DEFAULT);
Map<String, MappingMetaData> mappings2 = mapping1.mappings();
MappingMetaData mappingMetaData = mappings2.get(indexName);
Map<String, Object> sourceAsMap = mappingMetaData.getSourceAsMap();
So maybe someone of you has an Idea whats wrong here?
Thanks in advance

经过几个小时的搜索，似乎是Maven的缓存问题。
在删除了本地Maven仓库并重新加载资源之后，现在似乎可以正常工作了。
英文:
After hours of searching it seems that it was a chaching problem with maven.
After deleting my local maven repo an reload the sources it seems to work now.
