Summary

  • Changes the ReplacePowerMockito recipe to replace PowerMock dependencies with mockito-inline instead of mockito-core for Mockito 3.x/4.x

  • PowerMock features (static mocking, constructor mocking, final class mocking) require the inline mock maker, which is only bundled in mockito-inline for Mockito 3.x/4.x — mockito-core alone causes runtime failures

  • Closes https://github.com/moderneinc/customer-requests/issues/1934

Mockito 5.x

Mockito 5.x makes mockito-inline obsolete. All you need with that version forward is mockito-core. This has already been covered in the org.openrewrite.java.testing.mockito.Mockito4to5Only recipe.

recipeList:
  - org.openrewrite.java.testing.mockito.Mockito1to4Migration
  - org.openrewrite.java.dependencies.ChangeDependency:
      oldGroupId: org.mockito
      oldArtifactId: mockito-inline
      newArtifactId: mockito-core

PowerMock features (static mocking, constructor mocking, final class
mocking) require the inline mock maker, which is only bundled in
mockito-inline for Mockito 3.x/4.x. Using mockito-core alone causes
runtime failures when the migrated code calls Mockito.mockStatic().
…ine (#1934)

Replace hardcoded mockito-inline dependency with a ScanningRecipe that
detects mockStatic(), whenNew(), or @PrepareForTest usage and selects
mockito-inline only when needed, falling back to mockito-core otherwise.

Use Map<JavaProject, Boolean> in the accumulator so each sub-module
gets mockito-inline or mockito-core based on its own usage patterns.
