How to invoke Eclipse operations? [message #453567] Wed, 02 August 2006 18:46 Go to next message
Eclipse UserFriend
Hi all,

I'm writing my first RCP application. It's a simple one that simply
removes unused imports from a Java file using Eclipse's
OrganizeImportsOperation. My problem is that if my code actually tries
to construct an OrganizeImportsOperation, I get an exception at startup
(whether or not the code is executed!).

My entire log is below. But first, here is my code from
Application.java. Look in removeUnusedImports, a function that is not
called. If I uncomment the line to create a new
OrganizeImportsOperation, I get an "java.lang.IllegalStateException:
Workbench has not been created yet" exception at startup.

Can anyone help out?

Thanks,
David

That's a contradiction: Organize imports is part of JDT UI which is no
RCP. If you use that you'll drag in all the IDE related stuff.

JDT UI expects a workbench to be present.

Thanks for the reply. Currently with my plug-in I (1) Create an empty
Java project, (2) copy the file into the Java project, (3) open the
file, (4) run the "Cleanup" action. I can automate the first two steps
by pre-creating the project and copying the file into it. I can automate
the third step by having my plug-in do a refresh on the project then
search for any .java files to clean up. But how can I automate the
fourth step?

For example, I could modify my plug-in to do its action during Eclipse's
startup. Is there any way to start Eclipse hidden then automatically
shut it down after the plug-in finishes initializing? In a pinch I guess
I could have my plugin write "all done" to a file, then kill -9 Eclipse.
Perhaps I could also find some OS method to hide the Eclipse window as
it starts.

(I was trying I'd do an RCP application, with the stuff for the
workbench, so that I wouldn't have to start all of Eclipse. I was doing
this:

public void postWindowCreate() {
getWindowConfigurer().getWindow().getShell().setVisible(fals e);
}

in ApplicationWorkbenchWindowAdvisor to hide the UI of the app.)

Thanks again,
David

The problem with your first example was any operations you need to do
need to run withing the createAndRunWorkbench(*) method.

You could use the org.eclipse.ui.startup extension to call into one of
your classes. Basically they are run immediately after the workbench
becomes available (read the javadoc for the IStartup interface
carefully, though).

Also, you can check out how the standalone update manager works ... they
must instantiate most of the workbench and then run whatever command was
passed in on the command line. You can check out their code to see how
they do it (you are looking for the org.eclipse.update.* plugins).

Thanks for the excellent suggestion. However, are you sure they
instantiate the workbench? I did a search for "workbench" in
org.eclipse.update.core and got nothing. I also compiled their
standalone app and ran it, then tried inserting my code. I got the same
error as before during plugin startup:

Root exception:
java.lang.IllegalStateException: Workbench has not been created yet.
