=encoding utf8 =head1 NAME checkstyle - Java code quality tool =head1 SYNOPSIS checkstyle [B<-dEghjJtTV>] [B<-b>=I<xpath>] [B<-c>=I<configurationFile>] [B<-f>=I<format>] [B<-o>=I<outputPath>] [B<-p>=I<propertiesFile>] [B<-s>=I<suppressionLineColumnNumber>] [B<-w>=I<tabWidth>] [B<-e>=I<exclude>]… [B<-x>=I<excludeRegex>]… I<files>… =head1 DESCRIPTION Checkstyle verifies that the specified source code files adhere to the specified rules. By default, violations are reported to standard out in plain format. Checkstyle requires a configuration XML file that configures the checks to apply. =head1 OPTIONS =over =item I<files>… One or more source files to verify. =item B<-b>, B<--branch-matching-xpath>=I<xpath> Shows Abstract Syntax Tree (AST) branches that match given XPath query. =item B<-c>=I<configurationFile> Specifies the location of the file that defines the configuration modules. The location can either be a filesystem location, or a name passed to the C<ClassLoader.getResource()> method. =item B<-d>, B<--debug> Prints all debug logging of CheckStyle utility. =item B<-e>, B<--exclude>=I<exclude> Directory/file to exclude from CheckStyle. The path can be the full, absolute path, or relative to the current path. Multiple excludes are allowed. =item B<-E>, B<--executeIgnoredModules> Allows ignored modules to be run. =item B<-f>=I<format> Specifies the output format. Valid values: C<xml>, C<sarif>, C<plain> for C<XMLLogger>, C<SarifLogger>, and C<DefaultLogger> respectively. Defaults to C<plain>. =item B<-g>, B<--generate-xpath-suppression> Generates to output a suppression xml to use to suppress all violations from user’s config. Instead of printing every violation, all violations will be catched and single suppressions xml file will be printed out. Used only with B<-c> option. Output location can be specified with B<-o> option. =item B<-h>, B<--help> Show this help message and exit. =item B<-j>, B<--javadocTree> This option is used to print the Parse Tree of the Javadoc comment. The file has to contain only Javadoc comment content excluding C<'/**'> and C<'*/'> at the beginning and at the end respectively. It can only be used on a single file and cannot be combined with other options. =item B<-J>, B<--treeWithJavadoc> This option is used to display the Abstract Syntax Tree (AST) with Javadoc nodes of the specified file. It can only be used on a single file and cannot be combined with other options. =item B<-o>=I<outputPath> Sets the output file. Defaults to stdout. =item B<-p>=I<propertiesFile> Sets the property files to load. =item B<-s>=I<suppressionLineColumnNumber> Prints xpath suppressions at the file’s line and column position. Argument is the line and column number (separated by a C<:> ) in the file that the suppression should be generated for. The option cannot be used with other options and requires exactly one file to run on to be specified. Note that the generated result will have few queries, joined by pipe (C<|>). Together they will match all AST nodes on specified line and column. You need to choose only one and recheck that it works. Usage of all of them is also ok, but might result in undesirable matching and suppress other issues. =item B<-t>, B<--tree> This option is used to display the Abstract Syntax Tree (AST) without any comments of the specified file. It can only be used on a single file and cannot be combined with other options. =item B<-T>, B<--treeWithComments> This option is used to display the Abstract Syntax Tree (AST) with comment nodes excluding Javadoc of the specified file. It can only be used on a single file and cannot be combined with other options. =item B<-V>, B<--version> Print version information and exit. =item B<-w>, B<--tabWidth>=I<tabWidth> Sets the length of the tab character. Used only with B<-s> option. Default value is 8. =item B<-x>, B<--exclude-regexp>=I<excludeRegex> Directory/file pattern to exclude from CheckStyle. Multiple excludes are allowed. =back =head1 LICENSE CheckStyle is released under the L<GNU Lesser General Public License v2.1 or later|https://spdx.org/licenses/LGPL-2.1-or-later.html>. =head1 SEE ALSO L<https://checkstyle.org/>.
