I have a clean installation of Neo4j 3.5.22, and just copied these two files into plugins:
apoc-3.5.0.14-all.jar
neo4j-spatial-0.26.2-neo4j-3.5.2-server-plugin.jar
And then I ran the following commands:
CALL spatial.importShapefile('import/shp/highway');
CALL spatial.layers;
CALL spatial.withinDistance('highway', point({latitude:13,longitude:56}), 10000);
All three succeeded. I got the highway shapefile as an example from the code repository. Perhaps there is something specific about your shapefile causing the error? Do you have an error messages in the neo4j.log or the debug.log files that might relate to this?
Also, where did you get the file apoc-3.5.0.14.jar? When I look at the APOC releases page at Releases · neo4j-contrib/neo4j-apoc-procedures · GitHub I can only download the file apoc-3.5.0.14-all.jar. Yours has no -all in the name. I don't know if that matters, but was curious.
