Top 7 Java Code Quality Projects

  • Checkstyle

    Checkstyle is a development tool to help programmers write Java code that adheres to a coding standard. By default it supports the Google Java Style Guide and Sun Code Conventions, but is highly configurable. It can be invoked with an ANT task and a command line program.

  • PMD

    An extensible multilanguage static code analyzer.

    Project mention: Custom Gradle Plugin for Unified Static Code Analysis | | 2023-02-04

    PMD and Checkstyle are static analysis tools that check your code on each project build. Gradle allows to apply them easily.

  • Tailor

  • gradle-baseline

    A set of Gradle plugins that configure default code quality tools for developers.

  • error-prone-support

    Error Prone extensions: extra bug checkers and a large battery of Refaster rules.

    Project mention: Picnic Open-sources Error Prone Support | | 2022-10-13

    Maybe the checks and rules are already usable for you with these two checks disabled? By the way, it is not required to use either Guava or New Relic to be able to integrate Error Prone Support. For example, the `ScheduledTransactionTrace` BugCheck will just be a no-op if you don't use New Relic :). W.r.t. to your fourth point, if you are sure there is not a change in ordering and you indeed found a false positive could you maybe file a bug report :)? We want to fix all false positives where possible of course.

  • Sonar

    Write Clean Java Code. Always.. Sonar helps you commit clean code every time. With over 600 unique rules to find Java bugs, code smells & vulnerabilities, Sonar finds the issues while you focus on the work.
