Maven Plugin v3.11.0

Added

• Add <cleanup>false</cleanup> to <googleJavaFormat> to disable google-java-format's non-whitespace cleanups. (#3157)
• Add a <maxLineLength> parameter to <googleJavaFormat>. (#3151)
  Overrides the 100-column limit prescribed by the GOOGLE and AOSP styles; requires google-java-format 2.0.0 or later.

Changes

• Bump default google-java-format version 1.36.1 -> 2.0.0. (#3157)
  This version applies some small non-whitespace cleanups by default (removing redundant semicolons, empty annotation parentheses, and parentheses around single lambda parameters), which can be disabled with <cleanup>false</cleanup>.

Maven Plugin v3.10.4

Changes

• Bump default eclipse version from 4.40 to 4.41.
• Bump default gherkin version 42.0.0 -> 42.0.1. (#3088)
• Bump default jackson version 2.22.2 -> 2.22.3. (#3101)
• Bump default palantir-java-format version 2.98.0 -> 2.102.0. (#3103, #3132)
• Bump default mockito-core version 5.23.0 -> 5.24.0. (#3106)
• Bump default greclipse version to latest 4.40 -> 4.41. (#3123)
• Bump default ktfmt version 0.64 -> 0.65. (#3135)
  Which moved to the org.jetbrains.kotlinx:ktfmt coordinate and org.jetbrains.kotlinx.ktfmt package. Older versions are still supported.
• Bump default palantir-java-format version 2.99.0 -> 2.102.0. (#3132)

Fixed

• Migrate Plexus component injection to JSR-330 and Maven parameter. (#3122)
• shortenFullyQualifiedTypes leaves a qualified name alone when the enclosing type extends or implements a type that is not in the same file, so an inherited member type cannot take the simple name. (#3117)
• expandWildcardImports no longer drops the import of a type that is only used to qualify a static member (such as Collections.sort(list) or TimeUnit.SECONDS), or the static import of a field or enum constant (such as PI from import static java.lang.Math.*), which produced code that did not compile. (#2833)

Maven Plugin v3.10.3

Changes

• Generate formatter defaults from version catalog. (#3045)
• Bump default gson version 2.13.2 -> 2.14.0. (#3045)
• Bump default zjsonpatch version 0.4.14 -> 0.4.16. (#3045)
• Bump default jackson-dataformat-yaml version 2.14.1 -> 2.20.1. (#3045)
• Bump default ktfmt version 0.63 -> 0.64. (2988)
• Bump default cleanthat version 2.25 -> 2.26. (#2882)
• Bump default jackson version 2.20.1 -> 2.22.2. (#2819)
• Bump default javaparser version 3.27.1 -> 3.28.2. (#3065)
• Bump default palantir-java-format version 2.80.0 -> 2.98.0. (#3068)
• Bump default scalafmt version 3.8.1 -> 3.11.5. (#2173)
• Bump default google-java-format version 1.30.0 -> 1.36.1. (#3075)
• Bump default gherkin-utils version 10.0.0 -> 12.0.2. (#2979)

Fixed

• Fix release signing by using Gradle's required eight-digit signing subkey ID. (#3105)
• Fix race when creating the npm install cache directory. ((#3096)
• GrEclipse no longer emits expected OSGi and nested-jar warnings during initialization. (#2445)
• typescript prettier() no longer emits a warning when its parser is already set to typescript. (#3098)
• <versionCatalog> preserves standalone comments at section boundaries and the end of the file. (#3048)
• <versionCatalog> preserves entries when comments contain unmatched brackets, preserves commas inside quoted strings, and keeps significant line boundaries in multiline entries. (#3042)
• <versionCatalog> now reports unfinished entries as lints at their starting line. These fail formatting by default, so upgrading may expose catalog errors that previously caused silent data loss. (#3042)
• Eclipse JDT formatter step no longer fails with NoClassDefFoundError or NoSuchMethodError when lombok is active as a JVM agent (e.g. -javaagent:lombok.jar in Eclipse/VS Code/Cursor). (#2795)

[Unreleased]

Added

• Add a groupArtifact option to PalantirJavaFormatStep. (#3179)

Fixed

• GrEclipse no longer leaves a file%3A... directory in the working directory. (#2019)
• DBeaver SQL formatter no longer prints an IndexOutOfBoundsException when a file starts with a keyword like SET. (#1552)
• ExpandWildcardImportsStep no longer fails with Symbol resolution not configured on records and other syntax newer than Java 11, and leaves files JavaParser cannot validate unchanged. (#2946)
• removeSemicolons() no longer removes semicolons inside dollar-slashy strings ($/ ... /$), after escaped triple quotes in multiline strings, or in multi-line for (init; cond; update) headers. (#2780)
• RemoveUnusedImportsStep and GoogleJavaFormatStep no longer remove imports that are only used by links in Markdown doc comments (///, JDK 23+). (#3161)
• forbidWildcardImports no longer reports import statements inside Java text blocks or comments. (#2997)

[4.11.0] - 2026-11-02

Added

• Add a cleanup option to GoogleJavaFormatStep to disable google-java-format's non-whitespace cleanups. (#3157)
• Add a maxLineLength option to GoogleJavaFormatStep. (#3151)
  Overrides the 100-column limit prescribed by the GOOGLE and AOSP styles. Requires google-java-format 2.0.0 or later, the bug-fixing major release which stabilized the configurable JavaFormatterOptions.Style introduced experimentally in 1.37.0 (no 1.38.0 was ever published).

Changes

• Bump default google-java-format version 1.36.1 -> 2.0.0. (#3157)

[4.10.4] - 2026-10-08

Changes

• Bump default Eclipse JDT formatter version from 4.40 to 4.41.
• GitPrePushHookInstaller takes optional parameter for pre push hook directory, instead of always writing to .git/hooks. (#3115
• Bump default gherkin version 42.0.0 -> 42.0.1. (#3088)
• Bump default jackson version 2.22.2 -> 2.22.3. (#3101)
• Bump default mockito-core version 5.23.0 -> 5.24.0. (#3106)
• Bump default greclipse version to latest 4.40 -> 4.41. (#3123)
• Bump default ktfmt version 0.64 -> 0.65. (#3135)
  Which moved to the org.jetbrains.kotlinx:ktfmt coordinate and org.jetbrains.kotlinx.ktfmt package. Older versions are still supported.
• Bump default palantir-java-format version 2.99.0 -> 2.102.0. (#3132)

Fixed

• shortenFullyQualifiedTypes no longer corrupts a method reference on a field/variable (localVar.field::method), which JavaParser parses as a type-shaped scope; such scopes now go through the same known-package / minimum-depth heuristic as other expression scopes before being treated as fully-qualified types. (#3133)
• shortenFullyQualifiedTypes leaves a qualified name alone when the enclosing type extends or implements a type that is not in the same file, so an inherited member type cannot take the simple name. (#3117)
• expandWildcardImports no longer drops the import of a type that is only used to qualify a static member (such as Collections.sort(list) or TimeUnit.SECONDS), or the static import of a field or enum constant (such as PI from import static java.lang.Math.*), which produced code that did not compile. (#2833)
