      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 
<https://maven.apache.org/plugins/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
    <https://maven.apache.org/plugins/maven-pmd-plugin/examples/upgrading-PMD-at-runtime.html>
 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 
<https://docs.pmd-code.org/pmd-doc-7.0.0/pmd_userdocs_migrating_to_pmd7.html#im-using-only-built-in-rules>
in the Migration Guide for PMD 7 
<https://docs.pmd-code.org/pmd-doc-7.0.0/pmd_userdocs_migrating_to_pmd7.html>.

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 
<https://docs.pmd-code.org/pmd-doc-7.0.0/pmd_userdocs_migrating_to_pmd7.html#im-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 
<https://issues.apache.org/jira/projects/MPMD/issues/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 <https://openjdk.org/jeps/456>

PMD also supports the following preview language features:

  * JEP 447: Statements before super(...) (Preview)
    <https://openjdk.org/jeps/447>
  * JEP 459: String Templates (Second Preview)
    <https://openjdk.org/jeps/459>
  * JEP 463: Implicitly Declared Classes and Instance Main Methods
    (Second Preview) <https://openjdk.org/jeps/463>

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|:

|exportPMD_JAVA_OPTS=--enable-preview 
pmdcheck--use-versionjava-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
    <https://sourceforge.net/p/pmd/news/2024/03/pmd_userdocs_cpd.html#suppression>
    through |CPD-ON|/|CPD-OFF| comment pairs.
  * See PR #4726 <https://github.com/pmd/pmd/pull/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) 
<https://github.com/pmd/pmd-designer/releases/tag/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 
<https://github.com/forcedotcom/salesforcedx-vscode>, 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 <https://github.com/apex-dev-tools/apex-parser>
    originally by
    Kevin Jones <https://github.com/nawforce> (@nawforce).
    This project provides the grammar for a ANTLR based parser.
  * Summit-AST <https://github.com/google/summit-ast> by Google
    <https://github.com/google> (@google
    <https://sourceforge.net/u/google/profile/>)
    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 
<https://docs.pmd-code.org/pmd-doc-7.0.0/pmd_userdocs_migrating_to_pmd7.html#apex-ast>.

With the new Apex parser, the new language constructs like
User Mode Database Operations 
<https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_classes_enforce_usermode.htm>
and the new Null Coalescing Operator |??| 
<https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/langCon_apex_NullCoalescingOperator.htm>
can be parsed now. PMD should be able to parse Apex code up to version 
60.0 (Spring '24).

See #3766 <https://github.com/pmd/pmd/issues/3766> for details.

          Changed: Visualforce

There was an inconsistency between the naming of the maven module and 
the language id. The language id
used the abbreviation "vf", while the maven module used the longer name 
"visualforce". This has been
solved by renaming the language module to its full name "visualforce". 
The java packages have
been renamed as well.

If you import rules, you also need to adjust the paths, e.g.

  * |category/vf/security.xml| ➡️ |category/visualforce/security.xml|


          Changed: HTML support

Support for HTML was introduced in PMD 6.55.0 as an experimental 
feature. With PMD 7.0.0 this
is now considered stable.


          Changed: Kotlin support

Support for Kotlin was introduced with PMD 7.0.0-rc1 as an experimental 
feature. With PMD 7.0.0 this
is now considered stable.


          Changed: Velocity Template Language (VTL)

The module was named just "vm" which was not a good name. Its module 
name, language id and
package names have been renamed to "velocity".

If you import rules, you also need to adjust the paths, e.g.

  * |category/vm/...| ➡️ |category/velocity/...|


        Rule Changes

*New Rules*

  * |OperationWithHighCostInLoop|
    <https://docs.pmd-code.org/pmd-doc-7.0.0/pmd_rules_apex_performance.html#operationwithhighcostinloop>
    finds Schema class methods called in a loop, which is a
    potential performance issue.
  * |UseExplicitTypes|
    <https://docs.pmd-code.org/pmd-doc-7.0.0/pmd_rules_java_codestyle.html#useexplicittypes>
    reports usages of |var| keyword, which was introduced with Java 10.
  * |MissingEncoding|
    <https://docs.pmd-code.org/pmd-doc-7.0.0/pmd_rules_xml_bestpractices.html#missingencoding>
    finds XML files without explicit encoding.

*Changed Rules*

  * |EmptyControlStatement|
    <https://docs.pmd-code.org/pmd-doc-7.0.0/pmd_rules_java_codestyle.html#emptycontrolstatement>:
    The rule has a new property to allow empty blocks when
    they contain a comment (|allowCommentedBlocks|).
  * |MethodNamingConventions|
    <https://docs.pmd-code.org/pmd-doc-7.0.0/pmd_rules_apex_codestyle.html#methodnamingconventions>:
    The deprecated rule property |skipTestMethodUnderscores| has
    been removed. It was actually deprecated since PMD 6.15.0, but was
    not mentioned in the release notes
    back then. Use the property |testPattern| instead to configure valid
    names for test methods.
  * |CommentRequired|
    <https://docs.pmd-code.org/pmd-doc-7.0.0/pmd_rules_java_documentation.html#commentrequired>:
    The deprecated property |headerCommentRequirement| has been removed.
    Use the property |classCommentRequirement| instead.
  * |NonSerializableClass|
    <https://docs.pmd-code.org/pmd-doc-7.0.0/pmd_rules_java_errorprone.html#nonserializableclass>:
    The deprecated property |prefix| has been removed
    without replacement. In a serializable class all fields have to be
    serializable regardless of the name.

*Renamed Rulesets*

  * |category/vf/security.xml| ➡️ |category/visualforce/security.xml|
  * |category/vm/bestpractices.xml| ➡️ |category/velocity/bestpractices.xml|
  * |category/vm/design.xml| ➡️ |category/velocity/design.xml|
  * |category/vm/errorprone.xml| ➡️ |category/velocity/errorprone.xml|
