v1.0.1 - the 1st stable release of the Code-Safe Java Member Reordering and Formatting tool

JHarmonizer 1.0.0 is the first public stable release of a Java source harmonization tool that reorders class members and format the source without casually breaking code.

It is built for teams and projects that want a deterministic Java class layout, but do not want to manually move fields, constructors, methods, initializer blocks, and nested types around during reviews.

What it does

• Reorders Java class members according to configurable rules.
• Preserves important declaration-order behavior so reordered code remains valid.
• Formats the final output with Palantir Java Format.
• Provides Maven plugin goals for automatic reorder and CI checks.
• Provides a standalone CLI fat JAR for non-Maven workflows.
• Supports read-only check-all and check-fast modes for CI.
• Allows local opt-outs with @jharmonizer:fully-off and @jharmonizer:sort-off.
• Includes documentation, benchmarks, contribution guidelines, and a GitHub Actions verification workflow.

Available workflows

• jharmonizer:reorder — rewrite sources in place.
• jharmonizer:check-all — report all files that need reordering.
• jharmonizer:check-fast — fail on the first non-conforming file.
• java -jar jharmonizer-cli.jar — run the same workflows outside Maven.

Notes

JHarmonizer is not just a whitespace formatter. It is focused on source structure: where class members live, how they are grouped, and how consistently that layout can be enforced across a codebase.
