PMD

Supported Version	Language	Website
6.27.0	Java 14.0.2	https://pmd.github.io

PMD is a static analysis tool to detect issues about code style, security, performance, etc. It supports multiple programming languages but Sider supports only Java.

Getting Started

To start using PMD, enable it in your repository settings.

Configuration

You can customize the analysis via sider.yml:

linter:
  pmd_java:
    dir: src
    rulesets:
      - category/java/errorprone.xml
      - path/to/custom-ruleset.xml
    encoding: Shift_JIS
    min_priority: 3

Name	Type	Default
root_dir	string	-
jvm_deps	string[][]	[]
dir	string	.
rulesets	string, string[]	(see below)
encoding	string	(PMD's default)
min_priority	number	(PMD's default)

dir

This option allows you to specify a directory to analyze.

rulesets

This option allows you to specify predefined rulesets or your custom rulesets.

Here are the predefined rulesets:

• category/java/bestpractices.xml
• category/java/codestyle.xml
• category/java/design.xml
• category/java/documentation.xml
• category/java/errorprone.xml
• category/java/multithreading.xml
• category/java/performance.xml
• category/java/security.xml

For example, you can specify both:

linter:
  pmd_java:
    rulesets:
      - category/java/security.xml
      - your_pmd_custom_rules.xml

If the option is omitted, Sider uses the default configuration.

You can configure predefined rules and writing your own rules via the XML configuration file. See the official documentation for more details.

encoding

This option allows you to specify an encoding of your Java source code.

min_priority

This option allows you to specify a rule priority threshold. Rules with lower priority than the specified value will not be used.
