Hi, all,
I'm planning to upgrade my GDS library 1.6.1 to higher version of OpenGDS 1.8.6 or 2.0.2， which my own algorithm is running with. My problem is , OpenGDS seems to be compiled and is running correctly in command line window, but test cases won't run in Eclipse.
For example, when I try to run the Junit test case for ~/alpha/alpha-proc/src/main/java/org/neo4j/gds/spanningtree/KSpanningTreeProc.java, the test case ~/alpha/alpha-proc/src/test/java/org/neo4j/gds/KSpanningTreeProcTest.java, which I import to my Eclipse project to test, it just failed to load a test database with null pointer exception. Here's the stack trace, any idea?
I think it may be some misconfigurations of pom.xml, and put it in the end.
I import ~/alpha/alpha-algo/src/test/java/org/neo4j/gds/impl/spanningTree/PrimTest.java too, and it runs fine.
GDS version: 1.8.6
Neo4j version: 4.4.5
Operating system: Windows 10
