Hi,
I am using jacoco in tcp server mode to collect coverage data for
integration tests. To launch my application, I use the following jvm argument
"-Djavaagent:org.jacoco.agent-0.8.2.jar=output=tcpserver,port=36302,address=*"
The application launches fine but when I try connecting to the port 36302 on ip
127.0.0.1, inisde the container, I get connection refused. What am I doing
incorrect here ?
Connecting to 127.0.0.1 PORT:6300

-------------------------
I am using ExecutionDataClient to dump data
public static void main(final String[] args) throws IOException {
String address = (String) args[0];
int port = Integer.parseInt(args[1]);
final FileOutputStream localFile = new
FileOutputStream(DESTFILE);
final ExecutionDataWriter localWriter = new ExecutionDataWriter(
localFile);
// Open a socket to the coverage agent:
System.out.println("Connecting to " + address + " PORT:" + port
);
// final Socket socket = new
Socket(InetAddress.getByName(address), port);
final Socket socket = new
Socket(InetAddress.getByName(address), port);
final RemoteControlWriter writer = new RemoteControlWriter(
socket.getOutputStream());
final RemoteControlReader reader = new RemoteControlReader(
socket.getInputStream());
reader.setSessionInfoVisitor(localWriter);
reader.setExecutionDataVisitor(localWriter);
// Send a dump command and read the response:
writer.visitDumpCommand(true, false);
if (!reader.read()) {
throw new IOException("Socket closed unexpectedly.");
}
socket.close();
localFile.close();
}
