Whenever using a log level, one should check if it is actually enabled, or otherwise skip the associate String creation and manipulation, as well as any method calls. An alternative to checking the log level are substituting parameters, formatters or lazy logging with lambdas. The available alternatives depend on the actual logging framework.

This version of the CodeQL Action was deprecated on January 18th, 2023, and is no longer updated or supported. For better performance, improved security, and new features, upgrade to v2. For more information, see https://github.blog/changelog/2023-01-18-code-scanning-codeql-action-v1-is-now-deprecated/

The following actions uses node12 which is deprecated and will be forced to run on node16: github/codeql-action/upload-sarif@v1. For more info: https://github.blog/changelog/2023-06-13-github-actions-all-actions-will-run-on-node16-instead-of-node12-by-default/

The following actions use a deprecated Node.js version and will be forced to run on node20: actions/checkout@v3, actions/setup-java@v3, pmd/pmd-github-action@v1, github/codeql-action/upload-sarif@v1.

Reports import statements that can be removed. They are either unused, duplicated, or the members they import are already implicitly in scope, because they're in java.lang, or the current package. If some imports cannot be resolved, for instance because you run PMD with an incomplete auxiliary classpath, some imports may be conservatively marked as used even if they're not to avoid false positives.

A logger should normally be defined private static final and be associated with the correct class. `private final Log log;` is also allowed for rare cases where loggers need to be passed around, with the restriction that the logger needs to be passed into the constructor.

This rule detects when a constructor is not necessary; i.e., when there is only one constructor and the constructor is identical to the default constructor. The default constructor should has same access modifier as the declaring class. In an enum type, the default constructor is implicitly private.

Uncommented Empty Constructor finds instances where a constructor does not contain statements, but there is no comment. By explicitly commenting empty constructors it is easier to distinguish between intentional (commented) and unintentional empty constructors.

Enforce a policy for braces on control statements. It is recommended to use braces on 'if ... else' statements and loop statements, even if they are optional. This usually makes the code clearer, and helps prepare the future when you need to add another statement. That said, this rule lets you control which statements are required to have braces via properties. From 6.2.0 on, this rule supersedes WhileLoopMustUseBraces, ForLoopMustUseBraces, IfStmtMustUseBraces, and IfElseStmtMustUseBraces.
