Build graph over wire indexing error

[landonreed]

Expected behavior

Build graph over wire should not fail.

Observed behavior

The A streetIndex has already been defined. Can't you just reuse the existing one? exception is thrown when attempting to build graph over wire.

OpenTripPlanner/src/main/java/org/opentripplanner/routing/graph/Graph.java

Lines 705 to 708 in 638da5f

	if (streetIndex != null) {
	throw new UnsupportedOperationException(
	"A streetIndex has already been defined. Can't you just reuse the existing one?"
	);

Note: this exception is also thrown if running otp with args --build --inMemory. Basically any time the following lines are run in succession:

graphBuilder.run();
graph.index(new DefaultStreetVertexIndexFactory());

Version of OTP used (exact commit hash or JAR name)

Data sets in use (links to GTFS and OSM PBF files)

any

Command line used to start OTP

OTP args: --server --insecure --router default

Router config and graph build config JSON

n/a

Steps to reproduce the problem

Recommended approach is to run Data Tools and OTP on localhost, define an OTP deployment server in Data Tools (using internalUrl field with OTP server location http://localhost:8080/otp), and deploy a single small feed to OTP.
