<b>ATTENTION:</b> Links to config and sample files in the following table reference to latest (not released yet) config. Config might be slightly different from what we have in the latest release. Please always use config that is embedded to jar or use a custom version copied from one that matches your checkstyle version. </p>
<p>
Sample files consists of files that show what code is correct and what is not. The incorrect code is marked with a "violation" comment and a message explaining the incorrect code. All the sections have their own sample files that contain example code for the particular section. Please keep in mind that some section's sample files might contain false positive violations; such sections are marked with a blue tick, showing that Checkstyle does not fully cover that section. </p>

We can detect URL with protocol type as http://, https:// etc. <br />
However, there are some cases we cannot cover, for example: <a href="https://webtoolkit.googleblog.com/2008/07/getting-to-really-know-gwt-part-1-jsni.html" class="externalLink"> JSNI</a>(see reason at: <a href="https://github.com/checkstyle/checkstyle/issues/14938" class="externalLink">#14938</a>), detecting command lines, long identifiers and so on. <br />
<br />
To disable this rule for above cases, please use <a href="filters/suppresswithnearbytextfilter.html#SuppressWithNearbyTextFilter"> SuppressWithNearbyTextFilter </a>. Check out <a href="#Google_Suppressions">Suppressions</a> section to learn how to use this suppression. <br />
