Changes since 7.0.0-rc4

This section lists the most important changes from the last release candidate.
The remaining section describes the complete release notes for 7.0.0.

New and Noteworthy

Maven PMD Plugin compatibility with PMD 7

In order to use PMD 7 with maven-pmd-plugin a new
compatibility module has been created. This allows to use PMD 7 by simply adding one additional dependency:

1. Follow the guide Upgrading PMD at Runtime
2. Add additionally the following dependency:

<dependency>
  <groupId>net.sourceforge.pmd</groupId>
  <artifactId>pmd-compat6</artifactId>
  <version>${pmdVersion}</version>
</dependency>

It is important to add this dependency as the first in the list, so that maven-pmd-plugin sees the (old)
compatible versions of some classes.

This module is available beginning with version 7.0.0-rc4 and will be there at least for the first
final version PMD 7 (7.0.0). It's not decided yet, whether we will keep updating it, after PMD 7 is finally
released.

Note: This compatibility module only works for the built-in rules, that are still available in PMD 7. E.g. you need
to review your rulesets and look out for deprecated rules and such. See the use case
I'm using only built-in rules
in the Migration Guide for PMD 7.

As PMD 7 revamped the Java module, if you have custom rules, you need to migrate these rules.
See the use case I'm using custom rules
in the Migration Guide.

Note: Once the default version of PMD is upgraded to PMD7 in maven-pmd-plugin
(see MPMD-379), this
compatibility module is no longer needed. The module pmd-compat6 might not be maintained then
any further, hence it is already declared as deprecated.

No guarantee is given, that the (deprecated) module pmd-compat6 is being maintained over the
whole lifetime of PMD 7.

Java 22 Support

This release of PMD brings support for Java 22. There are the following new standard language features,
that are supported now:

• JEP 456: Unnamed Variables & Patterns

PMD also supports the following preview language features:

• JEP 447: Statements before super(...) (Preview)
• JEP 459: String Templates (Second Preview)
• JEP 463: Implicitly Declared Classes and Instance Main Methods (Second Preview)

In order to analyze a project with PMD that uses these language features,
you'll need to enable it via the environment variable PMD_JAVA_OPTS and select the new language
version 22-preview:

export PMD_JAVA_OPTS=--enable-preview
pmd check --use-version java-22-preview ...

Note: Support for Java 20 preview language features have been removed. The version "20-preview" is no longer available.

Swift Support

• limited support for Swift 5.9 (Macro Expansions)

Groovy Support (CPD)

• We now support parsing all Groovy features from Groovy 3 and 4.
• We now support suppression through CPD-ON/CPD-OFF comment pairs.
• See PR #4726 for details.

Updated PMD Designer

This PMD release ships a new version of the pmd-designer. The designer artifact has been
renamed from "pmd-ui" to "pmd-designer". While the designer still works with Java 8, the
recommended Java Runtime is Java 11 (or later) with OpenJFX 17 (or later).

For the detailed changes, see PMD Designer Changelog (7.0.0).

Apex Support: Replaced Jorje with fully open source front-end

When PMD added Apex support with version 5.5.0, it utilized the Apex Jorje library to parse Apex source
and generate an AST. This library is however a binary-blob provided as part of the
Salesforce Extensions for VS Code, and it is closed-source.

This causes problems, if binary blobs are not allowed by e.g. a company-wide policy. In that case, the Jorje
library prevented that PMD Apex could be used at all.

Also having access to the source code, enhancements and modifications are easier to do.

Under the hood, we use two open source libraries instead:

• apex-parser originally by
  Kevin Jones (@nawforce).
  This project provides the grammar for a ANTLR based parser.
• Summit-AST by Google (@google)
  This project translates the ANTLR parse tree into an AST, that is similar to the AST Jorje provided.
  Note: This is not an official Google product.

Although the parser is completely switched, there are only little known changes to the AST.
These are documented in the Migration Guide for PMD 7: Apex AST.

With the new Apex parser, the new language constructs like
[User Mode Database Operations...

The remaining section describes the complete release notes for 7.0.0.

New and Noteworthy

Migration Guide for PMD 7

A detailed documentation of required changes are available in the
Migration Guide for PMD 7.

Apex Jorje Updated

With the new version of Apex Jorje, the new language constructs like User Mode Database Operations
can be parsed now. PMD should now be able to parse Apex code up to version 59.0 (Winter '23).

Java 21 Support

This release of PMD brings support for Java 21. There are the following new standard language features,

PMD also supports the following preview language features:

• JEP 430: String Templates (Preview)
• JEP 443: Unnamed Patterns and Variables (Preview)
• JEP 445: Unnamed Classes and Instance Main Methods (Preview)

In order to analyze a project with PMD that uses these language features,
you'll need to enable it via the environment variable PMD_JAVA_OPTS and select the new language
version 21-preview:

export PMD_JAVA_OPTS=--enable-preview
pmd check --use-version java-21-preview ...

Note: Support for Java 19 preview language features have been removed. The version "19-preview" is no longer available.

New CPD report format cpdhtml-v2.xslt

Thanks to @mohan-chinnappan-n a new CPD report format has been added which features a data table.
It uses an XSLT stylesheet to convert CPD's XML format into HTML.

See the example report.

  • #4546: [java] OverrideBothEqualsAndHashCode ignores records
• java-performance
  • #4458: [java] RedundantFieldInitializer: false positive with lombok's @Value

API Changes

• The following previously deprecated classes have been removed:

  • pmd-core
    • net.sourceforge.pmd.PMD
    • net.sourceforge.pmd.cli.PMDCommandLineInterface
    • net.sourceforge.pmd.cli.PMDParameters
    • net.sourceforge.pmd.cli.PmdParametersParseResult

• The asset filenames of PMD on GitHub Releases are
  now pmd-dist-<version>-bin.zip, pmd-dist-<version>-src.zip and pmd-dist-<version>-doc.zip.
  Keep that in mind, if you have an automated download script.

  The structure inside the ZIP files stay the same, e.g. we still provide inside the binary distribution
  ZIP file the base directory pmd-bin-<version>.

• The CLI option --stress (or -stress) has been removed without replacement.

• The CLI option --minimum-priority was changed with 7.0.0-rc1 to only take the following values:
  High, Medium High, Medium, Medium Low, Low. With 7.0.0-rc2 compatibility has been restored, so that the equivalent
  integer values (1 to 5) are supported as well.

• Replaced RuleViolation::getFilename with new RuleViolation#getFileId, that returns a
  FileId. This is an identifier for a TextFile
  and could represent a path name. This allows to have a separate display name, e.g. renderers use
  FileNameRenderer to either display the full path name or a relative path name
  (see Renderer#setFileNameRenderer and
  ConfigurableFileNameRenderer). Many places where we used a simple String for
  a path-like name before have been adapted to use the new FileId.

  See PR #4425 for details.

Changes since 7.0.0-rc1

This section lists the most important changes from the last release candidate.
The remaining section describes the complete release notes for 7.0.0.

API Changes

• Moved the two classes AntlrTokenizer and JavaCCTokenizer from
  internal package into package net.sourceforge.pmd.cpd.impl. These two classes are part of the API and
  are base classes for CPD language implementations.
• AntlrBaseRule is gone in favor of AbstractVisitorRule.
• The classes KotlinInnerNode and SwiftInnerNode
  are package-private now.
• The parameter order of addSourceFile has been swapped
  in order to have the same meaning as in 6.55.0. That will make it easier if you upgrade from 6.55.0 to 7.0.0.
  However, that means, that you need to change these method calls if you have migrated to 7.0.0-rc1 already.

Updated PMD Designer

This PMD release ships a new version of the pmd-designer.
For the changes, see PMD Designer Changelog.

Language Related Changes

• New: CPD support for TypeScript
• New: CPD support for Julia

Rule Changes

• ImmutableField: the property ignoredAnnotations has been removed. The property was
  deprecated since PMD 6.52.0.

• Support for Kotlin 1.8 grammar
• initially 2 built-in rules

Changed: JavaScript support

• latest version supports ES6 and also some new constructs (see Rhino])
• comments are retained

Changed: Language versions

• more predefined language versions for each supported language
• can be used to limit rule execution for specific versions only with minimumLanguageVersion and
  maximumLanguageVersion attributes.

🌟 New and changed rules

New Rules

Apex

• UnusedMethod finds unused methods in your code.

Java

• UnnecessaryBoxing reports boxing and unboxing conversions that may be made implicit.

Kotlin

• FunctionNameTooShort
• OverrideBothEqualsAndHashcode

Swift

• ProhibitedInterfaceBuilder
• UnavailableFunction
• ForceCast
• ForceTry

Changed Rules

Java

• UnnecessaryFullyQualifiedName: the rule has two new properties,
  to selectively disable reporting on static field and method qualifiers. The rule also has been improved
  to be more precise.
• UselessParentheses: the rule has two new properties which control how strict
  the rule should be applied. With ignoreClarifying (default: true) parentheses that are strictly speaking
  not necessary are allowed, if they separate expressions of different precedence.
  The other property ignoreBalancing (default: true) is similar, in that it allows parentheses that help
  reading and understanding the expressions.
• LooseCoupling: the rule has a new property to allow some types to be coupled
  to (allowedTypes).
• EmptyCatchBlock: CloneNotSupportedException and InterruptedException are not
  special-cased anymore. Rename the exception parameter to ignored to ignore them.
• DontImportSun: sun.misc.Signal is not special-cased anymore.
• UseDiamondOperator: the property java7Compatibility is removed. The rule now
  handles Java 7 properly without a property.
• SingularField: Properties checkInnerClasses and disallowNotAssignment are removed.
  The rule is now more precise and will check these cases properly.
• UseUtilityClass: The property ignoredAnnotations has been removed.
• LawOfDemeter: the rule has a new property trustRadius. This defines the maximum degree
  of trusted data. The default of 1 is the most restrictive.
• CommentContent: The properties caseSensitive and disallowedTerms are removed. The
  new property fobiddenRegex can be used now to define the disallowed terms with a single regular
  expression.

Removed Rules

Many rules, that were previously deprecated have been finally removed.
See Detailed Release Notes for PMD 7 for the complete list.

🚨 API

The API of PMD has been growing over the years and needed some cleanup. The goal is, to
have a clear separation between a well-defined API and the implementation, which is internal.
This should help us in future development.

Also, there are some improvement and changes in different areas. For the ...
