Deep dives
The Journey to Automatic Refactoring
The transition to automatic refactoring for Java is driven by the challenges developers face when upgrading their code. Many engineers often find themselves overwhelmed by the manual labor required to move between versions, especially when large-scale migrations involve thousands of files. By utilizing the Open Rewrite project, developers can automate these transformations through 'recipes,' which provide specific rules for various upgrade tasks. An example is the migration from Spring Boot 2 to 3, which contains over 2,300 individual transformation steps, providing relief from the burden of needing to remember each one manually.
