how to customize the XtextBuilder [message #1009557]

Hi,

I have a language (Xyzzy) up and running and want to tweak the builder for it.

I subclassed the XtextBuilder to XyzzyBuilder and added the following to XyzzyRuntimeModule:

   public Class<? extends IncrementalProjectBuilder> bindIncrementalProjectBuilder() {
        return XyzzyBuilder.class;
   }

But now I am getting a lot of these errors:

1) No implementation for org.eclipse.core.runtime.IExtensionRegistry was bound.
  while locating org.eclipse.core.runtime.IExtensionRegistry
    for field at org.eclipse.xtext.builder.impl.RegistryBuilderParticipant.extensionRegistry(Unknown Source)
  while locating org.eclipse.xtext.builder.impl.RegistryBuilderParticipant
    for field at org.eclipse.xtext.builder.impl.XtextBuilder.participant(Unknown Source)
  at org.eclipse.xtext.service.MethodBasedModule.configure(MethodBasedModule.java:55)

1 error

I am not too familiar with Guice yet so I might be forgetting something or doing something stupid. I found Xtext's SharedModule class that seems to play a role here but I have no idea how to make it fly. I even tried this (giving me the same errors):

   public Class<? extends IncrementalProjectBuilder> bindIncrementalProjectBuilder() {
        return XtextBuilder.class; // return original builder !!
   }

Any hints or pointers?

Thanks,
Tom

Hi,

do you really want to change the builder for all Xtext languages or wouldn't it suffice to have an IXtextBuilderParticipant for your language?

The thing I like to do now is some extra cleaning at clean time (probably more later). I have only one language, so yes I want to add it to all my languages and at the same time no, I only want to changed the builder for my xyzzy language Wink

.

I looked at the IXtextBuilderParticipant before and thought it was only called on builds, not on clean. Your remark made me look again and I discovered that the it is also called at clean time, so it might do the trick for me.

Is the IXtextBuilderParticipant the designed way to add functionality to the xtext builder?

I will give it a shot... Thanks for the hint!

I am also facing the same issue when tried to customize XtextBuilder. In my scenario the builder participant wont work. I have extended the XtextBuilder similarly as mentioned in the first update by Tom. Has anyone solved the below issue.

1) No implementation for org.eclipse.core.runtime.IExtensionRegistry was bound.

You need to use the overriding guice module extension point for that

Please note: this will affect all Xtext Languages
