5 months ago @vnickolov O.K., I address it by myself after inspecting into those code lines of Neo4j 4.5+Open GDS 2.0, and the code lines of Open GDS 2.5.5, it's because of the code lines in org.neo4j.gds.kspanningtree.MyKSpanningTreeAlgorithmFactory.java, should add Tasks.leaf() to progressTask():

Hi,all, I'm trying to develop my own algorithm and procedure base on Open GDS 2.5.5, just setup my Eclipse Maven project by addressing the test-utils issue#294 with the help from @vnickolov, thanks a lot! Now that I've developed an algorithm PrimK，successfully have a Junit test on it, and create a procedure MyKSpanningTreeWriteProc and it's Junit test case, but the Junit test failed, I know little about the internal mechanism of Open GDS, so any help is appreciated, thanks in advance! Here's the source of my Eclipse Maven project, and here're the steps I take:
Stage 1 Create and test the algorithm.
Stage 2 Create a procedure.

@ValueClass @Configuration @SuppressWarnings("immutables:subtype") public interface MyKSpanningTreeWriteConfig extends SpanningTreeBaseConfig, WritePropertyConfig, WriteRelationshipConfig {
