Updates com.diffplug.spotless from 8.9.0 to 8.10.4

Release notes

Sourced from com.diffplug.spotless's releases.

Gradle Plugin v8.10.4

Changes

• Bump default eclipse version from 4.40 to 4.41.
• spotlessInstallGitPrePushHook now respects Git’s core.hooksPath when installing the pre-push hook, 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 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

• 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)

Gradle Plugin v8.10.3

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)
• We no longer publish a plugin marker for the legacy com.diffplug.gradle.spotless id, which has been redirecting to com.diffplug.spotless since 4.0. Builds that still request it now fail with Plugin [id: 'com.diffplug.gradle.spotless'] was not found instead of the migration message. (#3086)

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)
• Stop calling deprecated Configuration.setVisible from Gradle 9.0.0 (#3053)
• 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)

Gradle Plugin v8.10.2

Fixed

• shortenFullyQualifiedTypes() now shortens fully-qualified types used in expression contexts (such as static method calls, static fields, and enum constants) while avoiding imports that would change how existing unqualified type references resolve. (#3039)
• Eclipse JDT formatter step no longer fails with NoClassDefFoundError when lombok is active as a JVM agent (e.g. -javaagent:lombok.jar in Eclipse/VS Code/Cursor). (#2795)

Gradle Plugin v8.10.1
