1 year ago I have the exact same error message with the latest tag carma-simulation-1.0.1
The error is raised at TraciClient.java:97:
So I assume that sumoServerSocket is null and if so, it is an error from AbstractSumoAmbassador.java:428 that send socket without checking that it is not null
While digging into the problem I've found two additional "mistakes" regarding the logs, as can be seen in the output:
======================================================================wn)
| SUMO will now be started in GUI Mode. |
| Please make sure you have started Eclipse MOSAIC with "-w 0" |
| Start the simulation manually in SUMO-GUI. |
======================================================================There is a missing new line (\n) and an unaligned printing.
The missing newLine is at AbstractTimeManagement.java lines 168+231.
The code need to be changed from:
To:
progressLogger.info("Simulating: {}ns ({}s) - {}%" + newLine,And from:
To:
progressLogger.info("Simulating: {}ns ({}s / {}s) - {}% (RTF:{}, ETC:{})" + newLine,And the unaligned "box" is at LogStatements.java:64, the repeat value is 7 and not 14:
The code need to be changed from:
To:
System.out.println("| Please make sure you have started Eclipse MOSAIC with \"-w 0\"" + StringUtils.repeat(" ", 7) + "|");
