The Eclipse plugin can be debugged from inside the IDE while in the development phase, but once the plugin is installed in the IDE, we need to debug it remotely for bug resolution. In this quick tutorial, I'm going to explain how to debug an Eclipse plugin remotely.
Let's suppose we have developed our simple Hello World plugin and installed it in our IDE. Now, to debug the plugin remotely, please follow the steps below.
Open the first instance of Eclipse IDE pointing to the workspace where your Hello World plugin project is located.
Navigate to the eclipse.ini file of your IDE. Here is a screenshot of the location of the file in MacOS.
Now add the following JVM arguments to the file:
-vmargs -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044
Now, open another instance of the Eclipse IDE (on MacOS, use the command
open -a -n Eclipse in the terminal).This instance will point to a workspace different from the one which contains the Hello World plugin project.
Now, in the workspace containing the Hello World plugin project, make the following remote debug configurations/; Navigate Run -> Debug Configurations -> Remote Java Application.
Then hit the debug button. Also, do not forget to put break-points in the codes of the Hello World plugin to be debugged.
In the other workspace (which does not contain the Hello World plugin) try to use the Hello World plugin and it will be remotely debugged in the other instance of Eclipse.
In this brief tutorial, I have shown how to debug an Eclipse plugin remotely.
