Launch a swing application by using an eclipse plugin button

Question

I am currently trying to integrate a Swing application as an Eclipse plugin. I have in my workspace two separate projects : - MyApplication - MyPlugin

To launch my application I just need to call com.[...].Desktop.instance(); from Desktop.java in MyApplication, when I click on the button. I just want it to launch first so it's really basic.

Here's my code :

public void run(IAction action) {

com.[...].Desktop.instance();

}

And here's the error I get :

!ENTRY org.eclipse.ui 4 0 2017-03-21 12:33:18.862
!MESSAGE Unhandled event loop exception
!STACK 0
java.lang.NoClassDefFoundError: com/.../Desktop
at boutton_test.actions.SampleAction.run(SampleAction.java:44)
...

On my plugin project "properties" -> "Java Build Path" -> "Projects" MyApplication is well added, so I don't really understand why I get such an error.

I also tried something like this :

try {
Process MyApplication = Runtime.getRuntime().exec("javac Desktop.java");
MyApplication.waitFor();
} catch (IOException | InterruptedException e1) {
  e1.printStackTrace();
}

But when I click on the button nothing happens, and I get nothing in the logs. Any ideas ?

Answer 1

So the solution I found was to create a new plug-in from existing JAR Archives called MyApplicationplug, using the .jar from MyApplication.

Then in MyPlugin add it to dependencies, Manifest.MF -> Dependencies -> Add... -> MyApplicationplug

Somehow it worked without conflicts with the JVM.
