Eclipse RCP: Error when exporting Sample Eclipse Product

Question

I've set up jdk-15.0.2+7 from AdoptOpenJDK. I've set up Eclipse IDE for RCP and RAP Developers (version: 2020-12 (4.18.0), Build id: 20201210-1552). I started Eclipse, created Plug-in Project PortfolioAnalyzer with default settings:

• Target platform: Eclipse,
• Create a rich client application? Yes
• Plug-in Template: Eclipse 4 RCP Application
• Checkbox Create sample content (part, menu, command...): True

Then I

• open PortfolioAnalyzer.product with default Product Configuration Editor, tab Overview and click link Eclipse Product export wizard in Exporting section
• specify Destination directory: D:\rcp_out, all settings by default.

And get error:

D:\Work\Eclipse\Java\PortfolioAnalyzer\.metadata\.plugins\org.eclipse.pde.core\temp\org.eclipse.pde.container.feature\package.org.eclipse.pde.container.feature.win32.win32.x86_64.xml:477: The following error occurred while executing this line:
C:\Users\Vadim\.p2\pool\plugins\org.eclipse.pde.build_3.10.900.v20201111-1557\scripts\genericTargets.xml:240: A problem occured while invoking the director.
The following error occurred while executing this line:
D:\Work\Eclipse\Java\PortfolioAnalyzer\.metadata\.plugins\org.eclipse.pde.core\temp\org.eclipse.pde.container.feature\package.org.eclipse.pde.container.feature.win32.win32.x86_64.xml:477: The following error occurred while executing this line:

I've edited

C:\Users\Vadim\.p2\pool\plugins\org.eclipse.pde.build_3.10.900.v20201111-1557\scripts\genericTargets.xml

by adding in target runDirector the following line just after properties definitions:

<record name="d:/build.log" loglevel="verbose" append="false"/>

In the case I get the log file when the error occurs. This is its content:

Property "p2.director.log" has not been set

Could you explain how to fix the problem? Should p2.director.log property be set somehow? Or something wrong with org.eclipse.equinox.p2.iu?
