Re: [pdt-dev] Problem Exporting a Plugin with php.core Dependency -Steps to Reproduce

(Sorry, resending as original email did not include the PDT list)

Thank you Roy for your response. 

Are you saying that, in order to create new plugins that extend PDT, one must develop those plugins using source pulled from the CVS repo?  Is it not normal development procedures to use the distributed plugins?

Keep in mind that I am not trying to do development work on PDT itself. I am only plugging in to provided extension points.

Ok, few tips:

  1. Use the SDK releases of Eclipse Platform, WTP, GEF, EMF and DLTK, PDT.
  2. Read this wiki page to understand how to configure the development environment:



What PDT version do you use? 2.1 (CVS HEAD) or 2.0 (R2_0 branch)

Enjoy ;)

Subject: [pdt-dev] Problem Exporting a Plugin with php.core Dependency -Steps to Reproduce


Hi all,

In an effort to resolve this, I have a set of steps for an extremely simple plug-in project that I would expect to build.  The end result is, however, the same as what I reported in my previous email.  Please, if you have a moment, see if these same steps also produce an error for you. If so, I believe there is a serious error somewhere.  If not, then I would love to know what I'm doing wrong.

Knowing that the steps below might be overly detailed for most of you, I will also provide a brief synopsis:

Setup an Eclipse install with the PDT plugins.  Use Eclipse's new plug-in project wizard to create a new plugin.  Add dltk.core and php.core dependencies.  Add the php.core.phpMixinBuildVisitors extension.  Add a new "visitor" to that extension.  Try to package the new plugin using Eclipse's plug-in export wizard.


1.  Use the PDT installation page (http://wiki.eclipse.org/PDT/Installation) to setup your Eclipse to include PDT and DLTK. I specifically followed the From Update Site set of instructions.

2.  Launch Eclipse (I am using 3.4.1) into a clean workspace

3.  Create a new plug-project (New > Plugin Project).  I named mine "com.test.php"  Click "Next", leaving all values at their default, until you reach the "Templates" page

4.  At the "Templates" page, select the "Hello, World" plugin as the template to use and click "Finish".

5.  The project is created and the plugin editor is open. Select the "Dependencies" tab and add the following two dependencies:

     a.  org.eclipse.dltk.core

     b.  org.eclipse.php.core

6.  Select the "Extensions" tab and click the "Add..." button.  Select org.eclipse.php.core.phpMixinBuildVisitors and press "Finish"

7.  Righ-click  iorg.eclipse.php.core.phpMixinBuildVisitors in the list of extensions and select "Add > visitor" from the context menu.

8.  Select the new "visitor" added and click the "class*" link found in the right column, just next to the list of extensions

9.  In the "New Java Class" dialog that appears, leave all values at their defaults and click "Finish"

10.  Make sure everything has been saved and has built without error

11. Right-click your new project (e.g. com.test.php), and select "Export..." from the context menu

12.  Select "Plug-in Development > Deployable plug-ins and fragments". Click "Next"

13.  Set an export directory destination, leave all other values at their default, and click "FInish"

I receive an error dialog pointing me to a generated log file. The log contains a single build error:

# 2/8/09 9:56:02 PM CST
# Eclipse Java Compiler 0.883_R34x, 3.4.1 release, Copyright IBM Corp 2000, 2008. All rights reserved.

1. ERROR in C:\export\com.test.php\src\com\test2\php\PHPMixinBuildVisitorExtension.java (at line 4)
    org.eclipse.php.core.PHPMixinBuildVisitorExtension {
org.eclipse.php cannot be resolved to a type
1 problem (1 error)

Does anyone else see this problem?  Where is the error in this process?

Thanks for your suggestion Klaus. 

Yes, my manifest does contain an entry for the php.core plugin as a "Require-Bundle":

Require-Bundle: org.eclipse.ui,

I also tried using the "Plug-ins and Fragments" import wizard to bring both PDT dependencies into my workspace. When I do so, my project fails to build (at all, not just during the "plugin export") due to the following error:

The project was not built since its build path is incomplete. Cannot find the class file for org.eclipse.php.core.codeassist.IPHPCompletionRequestor. Fix the build path then try building this project

So to summarize:

  1. When the dependencies are pulled directly from my Eclipse installation (i.e. I let Eclipse reference its own set of installed plugins), everything works as you would expect.
  2. If I try to build as a plugin, or if I import the plugins as binaries into my workspace (and allow those to be the dependencies), I have build errors.

(And if it matters, the php.core and php.ui versions I have are

I'm really at a loss regarding this issue.  Its always been my experience that the solution to these types are problems are pretty simple and obvious, and I'm always embarrassed by the fact that I didn't figure it out on my own.  So any other suggestions or help, no matter how obvious it might seem, would be greatly appreciated.

Thanks again for your time,

This seems to be obvious, but did you define all "Require-Bundle:" in the file:
