为什么 jQAssistent 扫描失败？

Question

我每晚都在使用 jQAssistant Maven 插件扫描我们的软件。如果 Neo4J 数据库为空，则一切正常。但是后来，我得到了很多错误：

00:00:44.150 [WARNING] [0x14d108ce][myneo4jserver:7687][bolt-127303] Fatal error occurred in the pipeline
00:00:44.150 org.neo4j.driver.exceptions.DatabaseException: The shortest path algorithm does not work when the start and end nodes are the same. This can happen if you
00:00:44.150 perform a shortestPath search after a cartesian product that might have the same start and end nodes for some
00:00:44.150 of the rows passed to shortestPath. If you would rather not experience this exception, and can accept the
00:00:44.150 possibility of missing results for those rows, disable this in the Neo4j configuration by setting
00:00:44.150 `cypher.forbid_shortestpath_common_nodes` to false. If you cannot accept missing results, and really want the
00:00:44.150 shortestPath between two common nodes, then re-write the query using a standard Cypher variable length pattern
00:00:44.150 expression followed by ordering by path length and limiting to one result.

谁能告诉我哪里出了问题？

Answer 1

我现在使用 Jenkins 管道首先清理外部 JQAssistant 数据库，然后扫描软件。此后未发生此错误。
