PSR1 and PSR2 standards are missing

Does this plug-in use an old version of PHP CodeSniffer?

Issue confirmed under Eclipse Neon

I got around that by forcing my locally installed CodeSniffer:

/Applications/Eclipse.app/Contents/Eclipse/plugins/org.phpsrc.eclipse.pti.tools.codesniffer_1.3.0.R20111119000000/php/tools/phpcs.php

Change include line to the following:

include_once '/Users/youruser/.composer/vendor/squizlabs/php_codesniffer/CodeSniffer/CLI.php';

After that I referenced PSR2 in the settings via this path:

/Users/youruser/.composer/vendor/squizlabs/php_codesniffer/CodeSniffer/Standards/PSR2

Definitely, this plugin uses an old version of PHP_CodeSniffer : with eclipse Neon 4.3 and PDT 4.3, I got PHP_CodeSniffer 1.3, released in 2011... (latest release is 2.8.1, march 2017)

After trying many workarounds like installing PEAR manually, working aroung with "pti_phpcs.launch" file, etc. I was about to give up to get PSR2 support in eclipse, until I ended up on @binarious answer. His workaround actually still works! Thanks!

So here is another way (which I found less hacky) to update PHP_CodeSniffer support in eclipse with PTI (so it's working with PDT-ext):

1. Find where the PHP_CodeSniffer execution file ('phpcs.php') is.
   It depends on your eclipse installation. You can use the "print PHP output to console" in "PHP CodeSniffer" properties in eclipse. Mine was here:
   /opt/.p2/pool/plugins/org.phpsrc.eclipse.pti.tools.codesniffer_1.3.0.R20111119000000/php/tools/phpcs.php
2. Make a symbolic link in the php folder (parent of parent of 'phpcs.php') to your PHP_CodeSniffer installation path.
   No need to edit the phpcs.php file since it is actually searching for a local installation of PHP_CodeSniffer inside the php folder.
   ln -s /opt/.composer/vendor/squizlabs/php_codesniffer/CodeSniffer /opt/.p2/pool/plugins/org.phpsrc.eclipse.pti.tools.codesniffer_1.3.0.R20111119000000/php/
3. Manually add wanted standards from your PHP_CodeSniffer installation in eclipse preferences.
   Press New, name it (eg: "PSR1"), set path (eg: /opt/.composer/vendor/squizlabs/php_codesniffer/CodeSniffer/Standards/PSR1)
4. Enjoy!

Note: Installation methods of PHP_CodeSniffer. I used composer global installation, adapt your paths depending on your installation.
