Question

There is a special case , for example:

  1. There are three lib-module : testa, testb and testc

  2. testa compile succeed , testb compile failed , testc compile succeed

    • ./gradlew testa:aDebug BUILD SUCCESSFUL
    • ./gradlew testb:aDebug BUILD FAILED
    • ./gradlew testc:aDebug BUILD SUCCESSFUL
    • ./gradlew app:aDebug BUILD FAILED
  3. Your special case is need to testa -> testb ; testb -> testc

how todo
  1. Using substitute, it's easy :

    substitute project(':testa') with project(':testb')
    
    substitute project(':testb') with project(':testc')
    
  2. What we hope is testa will be final replaced by testc. However, the result will not reach .

how to solve

You can change the redirect map , add testa -> testc. You can find detail code in 'xbuild/deps-fix.gradle'.
