Please note that the Magento Marketplace’s automatic technical validation tool ignores such suppressions (e.g. // @codingStandardsIgnoreLine):
- github.com/mage2pro/core/issues/27#issuecomment-332604013
- github.com/mage2pro/core/issues/29#issuecomment-332607012
So, a suppression will not help you to upload your extension to Magento Marketplace.
If you think, that the Magento code validation tool («marketplace-eqp») reacts with a false positive on your extension, then I recommend to report in in the official issue tracker.
