运行单元测试时，我遇到了jar hell的问题。

我遇到了上述错误，并通过删除了不必要的jar文件解决了这些错误。

但是我面临以下两个jar的问题，即tomcat-embed-core-8.0.36.jar和hibernate-jpa-2.1-api-1.0.0.Final.jar。这两者之间有一个共同的类，我需要两个jar文件，任何人都可以向我解释如何解决此问题。我都需要jar文件。

我想在我正在使用的Elasticsearch中执行单元测试，Java-test-framework
我正在使用Elasticsearch-1.6.0 并参考以下链接以寻求帮助 https://www.elastic.co/guide/en/elasticsearch/reference/1.6/using-elasticsearch-test-classes .html https://github.com/elastic/elasticsearch/blob/master/core/src/test/java/org/elasticsearch/action/search/SearchRequestBuilderTests.java

这是代码

class CampaignESTest extends ESTestCase {

  def getCLient():MockTransportClient={
     val settings = Settings.builder()
                .put(Environment.PATH_HOME_SETTING.getKey(), Files.createTempDir().toString())
                .build();
     val client = new MockTransportClient(settings);  
     client
  }
 }

class CampaignTestSearch extends PlaySpec{
  val client=new CampaignESTest

val response = client.prepareSearch("dbtest")
      .setTypes(CAMPAIGN_COLLECTION_NAME)
      .setSearchType(SearchType.DFS_QUERY_THEN_FETCH)
      .addFields("uuid","campaignName","artworkID","activationDate","_source")
      .setQuery(query)
      .execute()
      .actionGet()
  }

我收到这个例外
