Hello Charlie, if you don’t want to write the execution data to a file you can start the agent e.g. in tcpclient mode. This is how for example our coverage launcher in Eclipse works:
1) Start an TCP server on an arbitrary port 2) Programmatically launch the JVM with the parameter -javaagent:pathToJacocoAgent=output=tcspclient,port=<port allocated in step 1> The agent will connect to the server and send execution data when the JVM shuts down or you can also request dumps at arbitrary points in time. Our example comes with basic execution data server: https://www.jacoco.org/jacoco/trunk/doc/api.html You might also take a look at the implementation for the Eclipse plugin: https://github.com/eclipse/eclemma/blob/master/org.eclipse.eclemma.core/src/org/eclipse/eclemma/internal/core/launching/AgentServer.java Regards, -marc > On 4.
