Hi

In my EarlyStartup plugin, I have a PRE_BUILD listener which does things,
but if these things failed, how to cancel the BUILD ?

Throw a runtine exception ?

This is the code to listen PRE_BUILD events.

ResourcesPlugin.getWorkspace().addResourceChangeListener(new
PreBuildProcess(), IResourceChangeEvent.PRE_BUILD);

Hi encom79,

What is the build you are talking about? Did you create your own builder or
are you talking about the java build? "When auto-build is turned on, all
installed builders will be invoked every time resources are added, removed,
or modified in the eclipse workspace". If you want to control the build
process you should disable the auto build and invoke the build when you see
fit in your resource change listener.

http://www.eclipse.org/articles/Article-Builders/builders.ht ml

To be able to better respond to your future questions I would recommend to be
more specific.

Best Regards,

Wim Jongman

This is simple.

Im using flex builder and i want to add a pre-build operation.

I have made a org.eclipse.ui.Startup plugin, and put the following line in
the earlyStartup() method :
ResourcesPlugin.getWorkspace().addResourceChangeListener(new
PreBuildProcess(), IResourceChangeEvent.PRE_BUILD);

This changeListener notify my PreBuildProcess that a build will run. I
works fine. But if something goes wrong in my pre-build process I want to
notify the build process to cancel but I dont know how to do that.

The ChangeListener contains this method void
resourceChanged(IResourceChangeEvent event) overridden by my
PreBuildProcess class. I errors occurs in my "resourceChanged" function I
tried to throw an OperationCanceledException but it does not works.

Hi encom79,

I see. I really don't think that the build can be cancelled by a
resourcechangelistener. I don't see any explicit methods and I doubt that a
misbehaving listener can cancel the build. Want do you want to achieve? Why
is it so important to cancel the build?

Regards,

Wim

The aim is to trigger the "run" and "debug" button press :/
There is no PRE_RUN or PRE_DEBUG, PRE_BUILD is the best and simplest way I
have found to run my process before the "run/debug".

In this PRE_BUILD process I launch some executable (GUI) in a thread then
the regular BUILD start by launching Adobe Flex/Air program.
If my executable in the PRE_BUILD failed I should not let Adobe Flex/Air
program to run :/
That's why I need to find a way to kill Adobe Flex/Air program.

Hi,

Can't you use the file modification hook? The file modification hook goes
into your checker which prevents the saving of the file which in turn will
not trigger the build.

Regards,

Wim

File modification validators
It's also possible that team repository providers will need to prevent or
intervene in the editing or saving of a file. The team plug-in accomplishes
this by using the extension point
org.eclipse.core.resources.fileModificationValidator to register a validator
that is called whenever a resource is to be modified.

<extension point="org.eclipse.core.resources.fileModificationValidator "
id="FileValidator">
<fileModificationValidator
class=" org.eclipse.team.internal.core.FileModificationValidatorMana ger "/>
</extension>
The supplied class must implement IFileModificationValidator, which is
called by the platform whenever a resource is saved or opened. The team
plug-in installs a file modification manager that can determine which team
provider is managing a resource and invoke its specific validator.
