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

first of all remove all debug points in eclipse

search for PID with server port
netstat -ano|find /i "7001"
replace 7001 with your port number in above line

sample o/p C:\Users\shaithal>netstat -ano|find /i "7001" TCP 127.0.0.1:51340 127.0.0.1:7001 SYN_SENT 17396

then kill that process taskkill /F /PID 17396

search for PID with debug port also netstat -ano|find /i "8453" 8453 is debug port in my case replace 8453 with your port number in above line

sample o/p

C:\Users\shaithal>netstat -ano|find /i "8453" TCP 0.0.0.0:8453 0.0.0.0:0 LISTENING 19904

then kill that process taskkill /F /PID 19904

Answer 2

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.
