neo4j spark 连接器：mvn clean install assembly：单个错误

Question

我正在研究 neo4j-spark 连接器。克隆并移动到目录后，我做了mvn clean install assembly:single。它抛出错误：

Tests in error: 
  runMatrixQueryDFSchema(org.neo4j.spark.Neo4jDataFrameTest): Job aborted due to stage failure: Task 0 in stage 3.0 failed 1 times, most recent failure: Lost task 0.0 in stage 3.0 (TID 12, localhost): java.util.NoSuchElementException: None.get

我该如何摆脱它？我需要做任何其他事情来为 Scala 2.11 构建 target/neo4j-spark-connector_2.11-full-2.0.0-M1.jar。我已经安装了 Spark 2.0.0。我将它保存在与 neo4j-spark-connector 相同的目录中。我需要将它保存在其他地方吗？如何让它工作？

Answer 1

此问题现已解决。你可以从 neo4j-spark-connector repository 获取最新的 pull 并让它工作。

谢谢。
