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

[Alex Panchenko <alex@xxxxxxxxx>]

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!
