To fix above error, kindly follow the below steps

Open PluginListGenerator.php file located at vendor/magento/framework/Interception.

Go to line no 414 or find the word “scopePriorityScheme” in PluginListGenerator.php file.

Replace the line

"$cacheId = implode('|', $this->scopePriorityScheme) . "|" . $this->cacheId;" 
"$cacheId = implode('-', $this->scopePriorityScheme) . "-" . $this->cacheId;"

This time compilation command, bin/magento setup:di:compile should work

The error you encountered during compilation in Magento 2.4.2 indicates that the file ProjectName/generated/metadata/primary|global|plugin-list.php could not be created because the directory does not exist. To resolve this issue, you can follow these steps:

  1. Ensure the generated directory exists: Verify that the generated directory exists in the root of your Magento installation. If it doesn't exist, create it manually.

  2. Set proper permissions: Make sure the generated directory and its subdirectories have the correct permissions. You can set the appropriate permissions using the following command:

    chmod -R 777 generated

    Note: It's important to ensure the correct ownership and permissions are set according to your server environment. The above command is an example, but you may need to adjust it based on your specific server configuration.

  3. Clear the generated code: Remove any existing generated code files to ensure a clean regeneration process. You can use the following command:

    rm -rf generated/*
  4. Recompile your code: Now, recompile your Magento code by running the following command:

    bin/magento setup:di:compile

    This command will regenerate the necessary files, including the plugin-list.php file that was causing the error.

  5. Verify the issue is resolved: After the compilation process completes, check if the error is resolved. If the plugin-list.php file is successfully generated, the compilation process should complete without any warnings or errors.

By following these steps, you should be able to resolve the error related to the missing plugin-list.php file during the compilation process in Magento 2.4.2.
