How to develop a plugin that depends on Python plugin?

I have a lot of *.spec files. In fact, those files are python script with my own extentions(like you don't need to import anything there are a lot of out of stock global functions you can use in the script)
I want to write a plugin to help the editing of *.spec files.
What I did is:
1. Create a plugin project, add python.jar to the dependencies of my project. And add "<depends>Pythonid</depends>" in "plugin.xml"
2. Create "SpecFileTypeFactory" like this:

public class SpecFileTypeFactory extends FileTypeFactory {
  @Override
  public void createFileTypes(@NotNull FileTypeConsumer consumer) {
    consumer.consume(PythonFileType.INSTANCE, new ExtensionFileNameMatcher("spec"));
  }
}

3. Register this factory in "plugin.xml"

<fileTypeFactory implementation="leojay.devtools.intellij.buildplugin.filetype.SpecFileTypeFactory"/>

4. Execute the plugin, install Python plugin, and restart the sandboxed intellij idea.

But I saw some errors:

Why those errors?

Thanks.

Oh, another question: How can I add global python functions for those spec files? I need auto completion and parameter info.

Thanks.

Please make sure that you've added the jars of the Python plugin to the classpath of the IntelliJ IDEA SDK and not as a separate library.

I don't think the currently released version of the Python plugin has any APIs for that.

Hi, I have the same question, I want to develop custom documentation provider that extends existing PythonDocumentationProvider,
but my plugin code seems to be not executed at all.

Here is my plugin.xml:

<idea-plugin version="2">

  ...
  <!-- please see http://confluence.jetbrains.net/display/IDEADEV/Build+Number+Ranges for description -->
  <idea-version since-build="107.105"/>

  <!-- please see http://confluence.jetbrains.net/display/IDEADEV/Plugin+Compatibility+with+IntelliJ+Platform+Products
       on how to target different products -->
  <depends>com.intellij.modules.lang</depends>

  <application-components>
    <!-- Add your application components here -->
  </application-components>

  <project-components>
    <!-- Add your project components here -->
  </project-components>

  <actions>
    <!-- Add your actions here -->
  </actions>

  <extensions defaultExtensionNs="com.intellij">
    <!-- Add your extensions here -->
      <lang.documentationProvider language="Python" implementationClass="com.xxx.MyDocumentationProvider"/>
  </extensions>
</idea-plugin>

add order="first" to your documentation provider definition and make sure to return null for cases which yours does not handle
