Ignoring unused parameter with code sniffer

Question

I'm running the codesniffer with the EcgM2 standard on my custom extension and I'm getting the warning

The method parameter $context is never used

for the InstallSchema.php file.
How can I make this warning go away?
My method looks like this (notice the SuppressWarnings at the top of it):

/**
 * {@inheritdoc}
 * @SuppressWarnings(PHPMD.ExcessiveMethodLength)
 * @SuppressWarnings(PHPMD.UnusedFormalParameter)
 */
public function install(SchemaSetupInterface $setup, ModuleContextInterface $context)
{
    //my install script here that does not use the parameter $context
}

Answer 1

I was able to hide the dirt under the rug like this:

// @codingStandardsIgnoreStart
public function install(SchemaSetupInterface $setup, ModuleContextInterface $context) 
{
// @codingStandardsIgnoreEnd
....
}

I'm not proud of it, but it works.

Answer 2

Update phpcs (squizlabs/PHP_CodeSniffer) to latest (v3.2.3 at 2017-03-06) and use like:

/**
 * {@inheritdoc}
 */
// phpcs:ignore Generic.CodeAnalysis.UnusedFunctionParameter
public function install(SchemaSetupInterface $setup, ModuleContextInterface $context)
{
    //my install script here that does not use the parameter $context
}

Answer 3

I'm pretty sure the suppress warning rule you will have to use is:

Generic.CodeAnalysis.UnusedFunctionParameter

So this should be the code to use in your PHP Docblock:

@SuppressWarnings(Generic.CodeAnalysis.UnusedFunctionParameter)

Answer 4

I think this is the right way:

/**
 * {@inheritdoc}
 * phpcs:disable Generic.CodeAnalysis.UnusedFunctionParameter
 */
public function install(SchemaSetupInterface $setup, ModuleContextInterface $context)
{
    //my install script here that does not use the parameter $context
}

Answer 5

Just in case if someone has the same configuration, it works for me but with OP's SuppressWarnings ! No other answer worked.

So @SuppressWarnings(PHPMD.UnusedFormalParameter) actually works with PHPMD.
