I would like to write a simple Ant task that would interact with an Eclipse workspace to get some information from it. I would like to be able to use the various Eclipse API’s (for example, IWorkspace).
My question is what would be the simplest way to go about doing this.
I have excellent knowledge of the Eclipse platform as a user of it – but none with development for Eclipse. I understand that, in runtime, my Ant task will have to be invoked under the same JRE as the workspace – that’s a restriction I’m willing to be bound to.
I started by creating a Java project to hold my Ant task. I believe that the only thing in my way now is how to define the JAR dependency on Eclipse’s JARs. I obviously don’t want to depend on one specific Eclipse JAR as these are versioned (for example, Eclipse’s “Resources” plugin). Is it possible to have my Java project buildtime-depend on “whatever the current JAR is for the Resources plugin”?
I think this article quite much addresses your problem: http://www.ibm.com/developerworks/rational/library/09/eclipsecustomanttasks/
It is targeted to the IBM Rational Application Developer, but that one is based on Eclipse and AFAIS there is not overly much non-eclipse-specific happening here, at least not regarding the specifics about how to make the task available in Eclipse (writing the plugin definition etc).
