Full Changelog: v1.11.0...v1.12.0

google-java-format now has improved support for running on JDK 17 early access builds.

Changes:

• Handle final variables in instanceof patterns (#588)
• Fix handling of annotations in compact record constructors (#574)
• Fix a crash in instanceof pattern handling (#594)
• Wrap multiple values in switch expression case (#540)
• Fix formatting of module trees after JDK-8255464
• Support sealed classes (#603)

google-java-format now supports running on JDK 16. The following flags are required when running on JDK 16, due to JEP 396: Strongly Encapsulate JDK Internals by Default:

java \
  --add-exports jdk.compiler/com.sun.tools.javac.api=ALL-UNNAMED \
  --add-exports jdk.compiler/com.sun.tools.javac.file=ALL-UNNAMED \
  --add-exports jdk.compiler/com.sun.tools.javac.parser=ALL-UNNAMED \
  --add-exports jdk.compiler/com.sun.tools.javac.tree=ALL-UNNAMED \
  --add-exports jdk.compiler/com.sun.tools.javac.util=ALL-UNNAMED \
  -jar google-java-format-1.10.0-all-deps.jar T...

Other changes:

• Handle extra ; in import lists (b769e81)
• Add missing space between unary - and negative literals (6da736d)
• Fix an off-by-one issue on the reflowing of string literals (b9fd8d2)

• Add support for yield statements (#489)
• Fix a crash in expression switches (#477)

Changes:

• The minimum supported runtime version is now JDK 11.
• Initial support for Java 14 language features, including preview features. (Only available when running the formatter on JDK 14 or newer.)
• Flag control of javadoc formatting (--skip-javadoc-formatting).
• Reflowing string literals that exceed the column limit.

Fixes

• Handle unary negation when formatting tabular arguments (#400)
• Remove trailing tabs from comments to make behavior idempotent (#422)
• Fix a crash on c-style arrays in parameters (#374)
• Fix import reorderer to handle single-line-comments in imports (f246638)
• Handle double semi-colons after package statements (5e114ca)

Changes

• Treat expressions ending in .stream() as a syntactic unit
• Keep going if a file cannot be read, and report a non-zero exit status, similar to handling of syntax errors.

Features

• Don't format annotations as block-like constructs (#159)
• Add horizontal whitespace between varargs specifiers and type annotations (#282)
• Don't add spaces to //$NON-NLS-x$ comments (#221)
• Unify breaks between type parameters
• Add support for --assume-filename

Incompatible changes

• Version 1.6.1 of the IntelliJ plugin now notifies if google-java-format hasn't been configured for new projects. (Version 1.6.0 of the plugin enabled the formatter by default, but this behaviour was reverted in 1.6.1. See #290.)

Bug Fixes

• Don't crash on empty enum declarations (#281)
• Don't crash on unusual line separators (#201)

Features:

• Improved support for checking if files are already formatted: --dry-run prints the paths of files whose contents would change if the formatter were run normally, and --set-exit-if-changed returns exit code 1 if there are any formatting changes. (#105)
• Added support for javac-style @params files. (#77).

Bug fixes:

• Improved partial formatting within switch statements (c63984a).
• Improved import ordering logic to handle imports not separated by newlines (7225e17, 8364f6c).
