How to suppress all checks for a file in Checkstyle?

I'm doing an override for a third party class and I want to suppress all checks for it (since I'm only keeping it around until the patch is accepted).

Is there a way to suppress all checks for a file?

I tried using "*" but that fails.

Solution 1:

Don't know whether you're using command line or in an IDE, but you'll basically need a suppresions file. If you're manually editing the Checkstyle config file, add a new module to it:

<module name="SuppressionFilter">
    <property name="file" value="mysuppressions.xml" />
</module>

Your mysuppression.xml can be something like:

<?xml version="1.0"?>

<!DOCTYPE suppressions PUBLIC
    "-//Puppy Crawl//DTD Suppressions 1.1//EN"
    "http://www.puppycrawl.com/dtds/suppressions_1_1.dtd">

<suppressions>
    <suppress files="TheClassToIgnore\.java" checks="[a-zA-Z0-9]*"/>
</suppressions>

The value for "files" attribute is basically a regex for your source files, and the value for the "checks" attribute is regex for what checks to skip ("[a-zA-Z0-9]*" basically means skip everything). This is the pattern you're looking for I guess?

Solution 2:

I was able to suppress the checks in a file by adding the SuppressionCommentFilter tag in my checks.xml:

First, I added the FileContentHolder tag as a child of TreeWalker tag (this step is not needed since version 8.1 of com.puppycrawl.tools:checkstyle):

<module name="TreeWalker">
    ...
    <module name="FileContentsHolder"/>
    ...
</module>

Then I added the SuppressionCommentFilter in the checks.xml (since version 8.1 of com.puppycrawl.tools:checkstyle - under "TreeWalker" node):

<module name="SuppressionCommentFilter"/>

In each file that I wanted to suppress the checks I inserted the following comment in the first line of the file:

// CHECKSTYLE:OFF

Solution 3:

aberrant80's answer helped a lot. With the help of his hint - using regex pattern matching, I was also able to suppress checkstyle for an entire package by adding this to the checkstyle-suppressions.xml file. For eg. to skip checkstyle checks on all auto generated java files under the jaxb package,

    <suppressions>
        <suppress checks="[a-zA-Z0-9]*" files="[\\/]jaxb[\\/]" />
    </suppressions>

Solution 4:

If you're using the Checkclipse Eclipse plugin for Checkstyle, you can include or exclude file patterns (including directories) by going to the Checkclipse > File Filter tab under project properties. For example, my project contains src and test directories at the top level. I want Checkstyle applied to only files in the src directory (omitting test), so I added an include pattern that looks like this:

src/.+java$

As you can see, it uses a regex-style syntax for pattern specification.
