Maven Eclipse Debug “JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)”

Question

I\'m trying to debug Maven tests in Eclipse. When I launch tests with the maven option maven.surefire.debug, I get this error :

ERROR: transport error 202: b         


        

Answer 1

Just for documentation, I had the exact same error, running on my local:

ERROR: transport error 202: bind failed: Address already in use FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197) ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)

in my case the port wasn't the issue, but the host file. The solution is to add/re-add/uncomment:

127.0.0.1 localhost

The config file sets localhost as default, so a solution is add that host or change it for a custom one.
