Checkstyle - Exclude folder

Question

I want to ignore a specific folder (named generated-sources) from my checkstyle reports, because they are generated.

I\'m using eclipse-cs for displaying my violatio

Answer 1

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

this works :)

Answer 2

Additionally to the answer from Philipp, I had to use an absolute pathname ( :-( ) for the suppression file:

<module name="SuppressionFilter">
    <property name="file" value="/Users/xxx/workspace/suppressions.xml"/>
</module>

Looks like the Checkstyle plugin is not using the project home directory.

(at least under eclipse luna / Mac OS X)

Answer 3

As pointed by Thomas Welsch in his answer, there appears to be a problem with using relative pathname for the suppression xml file.

For gradle builds, This gist suggests a workaround:

in build.gradle:

checkstyle {
    // use one common config file for all subprojects
    configFile = project(':').file('config/checkstyle/checkstyle.xml')
    configProperties = [ "suppressionFile" : project(':').file('config/checkstyle/suppressions.xml')]
 }

in checkstyle.xml:

<module name="SuppressionFilter">
    <property name="file" value="${suppressionFile}" default="suppressions.xml"/>
</module>

(the default value allows IDE plugins, that do not have the gradle variable sorted out, to work correctly)
