Дедупликация: различное содержимое файла sbt-Assembly

0 голосов
/ 08 июня 2018

У меня есть мульти-проект, созданный с использованием sbt, и я хотел бы создать исполняемый файл jar с использованием плагина sbt-assembly.Тем не менее, я получаю сообщение об ошибке при создании файла JAR: 

[error] deduplicate: different file contents found in the following:
[error] /home/user/.ivy2/cache/org.slf4j/slf4j-api/jars/slf4j-api-1.7.25.jar:org/slf4j/helpers/Util.class
[error] /home/user/.ivy2/cache/neo4j-contrib/neo4j-spark-connector/jars/neo4j-spark-connector-2.1.0-M4.jar:org/slf4j/helpers/Util.class

Что я должен добавить в стратегии слияния, чтобы исправить эту ошибку?Я определил стратегию слияния для org.neo4j и org.slf4j, но, похоже, она не работает.
