I'm writing automation test. There are some steps that require some linux commands, like: mkdir, cd, vim, mkdir, cd, vim, terraform init, terraform apply, terraform destroy ... I'm not sure about how to make stable automation for such steps in Java.
I'm expecting to automate the next linux commands: mkdir, cd, vim, terraform init, terraform apply, terraform destroy

Two part question:
1) I have the requirement to attach the jacoco agent to an already running JVM, and per this comment on a Github issue, this was not possible as of 26th July 2018. Has support for this been implemented in the v0.8.5? Because the changelogs do not mention it.
2) If I start a jacoco agent as such:
java -javaagent:jacocoagent.jar=dumponexit=false,output=tcpserver,address=*,port=6300 -jar my-app-0.0.1-SNAPSHOT.jar
Is it possible to gracefully kill the tcpserver that starts up only while keeping the jar running. I am looking for an alternative to having to writing a script that would need to look up the PID on port 6300 and kill the process. Preferably a jacoco cli command but the API Docs do not mention it.

Is it even possible to start OpenVPN trough Java application? If it is possible what is the best way to do it so it's cross-platform and works on all platforms that have OpenVPN installed.
You can run openvpn with Java like this:
Runtime rt = Runtime.getRuntime();
Process pr = rt.exec("openvpn your_config.ovpn");
This will run openvpn via the command line. It is cross platform, too, as it will work on Mac, Linux and Windows.

I am new to Jenkins, I configured Jenkins with my CVS and I am stuck, after building the project using Jenkins I need it to be deployed automatically into the server so I can access the project.
This can be achieved by adding a "post-build" action in Jenkins, action of type can be "Deploy war/ear to a container" - that let's you define your configuration. Your question is too broad. I would suggest you read up on jenkin configurations or at least tinker with it.

I'm working on a java program that needs to be able to connect to a remote server and execute system commands. How would I create a command shell that looked exactly the same as windows command prompt for the client, but executes the commands on the remote server? Thx in advance
It's possible to do, but it's not easy - java has never been great for command-line operation. If you want to do it, look for java-based SSH implementations.
On the other hand, if the user will be running the java program from the command-line, it may be possible to execute an ssh command on the same terminal.
Here is a page that describes executing an external program from java: http://alvinalexander.com/java/java-exec-processbuilder-process-1.

As tomcat server is completely developed in Java, yet its installation file(.exe) are available for windows. As tomcat is open source, does the process of converting this java server application into windows installation file also documented anywhere. Which tool they use and how its works. How have they created UI wizard to take user inputs and do the registry entry and install tomcat as service.
Regards
They use Nullsoft Installer called from the ant build.
The nsi script can be found on svn, as well as all of tomcat code.
