Re: [Dltk-dev] Adding org.eclipse.core.resources.builders to a ScriptNat

[Robert Gruendler <robert@xxxxxxxxxxx>]

Hi Alex,

the BUILDER_ID was the problem, thanks. Now the error in the "Builders" page is gone,

and i see the Builder name i assigned in the plugin.xml.

Unfortunately, the builder is not called at all. I've created a test.txt file in the 

project, added some text, saved it. Am i missing something or shouldn't 

the builder be passed the delta then? I've also tried to clean the project,

but my builder doesn't event get instantiated. 

Also, i've tried the org.eclipse.dltk.core.builder extension, but this

builder never gets created (i've assigne the plugin nature to the extension).

best

Hi Robert,

What is the value of SymfonyYamlBuilder.BUILDER_ID? It should be plugin_id + '.' + builder_id, 

e.g. in DLTKCore: public static final String BUILDER_ID = PLUGIN_ID + ".scriptbuilder"; //$NON-NLS-1$

Another way for this task is implementing org.eclipse.dltk.core.builder.IScriptBuilder

and contributing it via <extension point="org.eclipse.dltk.core.builder">

Regards,

Alex

Subject: [Dltk-dev] Adding org.eclipse.core.resources.builders to a ScriptNature

Hi all,

my Project uses the org.eclipse.dltk.core.buildParticipant  extensionpoint to 

hook into the build process of php files (i'm extending PDT). This works

already fine for php resources. 

However, i'd need a org.eclipse.core.resources.builders extension point too,

to parse resources other than php files.

The problem is, that the regular builder can't be found in the project properties

"Builders" page. The additional builder shows up on the "Builders" page, but

it says "Missing builder: (com.dubture.symfony2.internal.core.builder.SymfonyYamlBuilder)".

This is my plugin.xml:

<plugin>

   <extension

         id="com.dubture.symfony2.core.nature"

         point="org.eclipse.core.resources.natures">

      <runtime>

         <run

               class="com.dubture.symfony2.core.SymfonyNature">

         </run>

      </runtime>

   </extension>

   <extension

         point="org.eclipse.dltk.core.buildParticipant">

      <buildParticipant

            class="com.dubture.symfony2.internal.core.builder.SymfonyBuildParticipantFactory"

            id="com.dubture.symfony2.core.buildParticipant.parser"

            name="Symfony 2 Parser"

            nature="org.eclipse.php.core.PHPNature">

      </buildParticipant>

   </extension>

   <extension

         id="SymfonBuilder"

         name="Symfony Yaml Builder"

         point="org.eclipse.core.resources.builders">

      <builder

            callOnEmptyDelta="true"

            hasNature="true">

         <run

               class="com.dubture.symfony2.internal.core.builder.SymfonyYamlBuilder">

         </run>

      </builder>

   </extension>

</plugin>

The Nature extends ScriptNature, and adds the builder in the configure() method like this:

IProjectDescription desc = project.getDescription();

ICommand[] commands = desc.getBuildSpec();

for (int i = 0; i < commands.length; ++i) {

if (commands[i].getBuilderName().equals(SymfonyYamlBuilder.BUILDER_ID)) {

return;

}

}

ICommand[] newCommands = new ICommand[commands.length + 1];

System.arraycopy(commands, 0, newCommands, 0, commands.length);

ICommand command = desc.newCommand();

command.setBuilderName(SymfonyYamlBuilder.BUILDER_ID);

newCommands[newCommands.length - 1] = command;

desc.setBuildSpec(newCommands);

project.setDescription(desc, null);

Has anyone a hint why the builder can't be loaded?

thanks!
