Root Cause

Two or more modules depend on each other directly or transitively, causing a circular dependency.

generic

中文

两个或多个模块直接或间接相互依赖，导致循环依赖。

Workarounds

  1. 90% success Refactor the project to remove the circular dependency by extracting shared classes into a new module 
    Create a new module 'shared' and move common code there, then have both modules depend on 'shared'.
  2. 70% success Use dependency exclusions to break the cycle 
    <dependency><groupId>com.example</groupId><artifactId>module-a</artifactId><exclusions><exclusion><groupId>com.example</groupId><artifactId>my-app</artifactId></exclusion></exclusions></dependency>

Dead Ends

Common approaches that don't work:

  1. Removing one dependency entirely without refactoring code 80% fail

    The code may rely on classes from that dependency, causing compilation errors.

  2. Using optional dependencies to break the cycle 90% fail

    Optional dependencies are still resolved during compilation, so the cycle persists.
