Способ 1: Сгенерируйте пакет har из библиотеки и добавьте его в папку lib.
       добавьте следующий код в gradle записи
    
    implementation fileTree(dir: 'libs', include: ['*.jar', '*.har'])
    annotationProcessor files('libs/butterknife_compiler.jar')

Способ 2: 
    allprojects{ 
        repositories{ 
            mavenCentral() 
        } 
    }
    implementation 'io.openharmony.tpc.thirdlib:butterKnife:1.0.2'
    annotationProcessor 'io.openharmony.tpc.thirdlib:butterknife-compiler:1.0.2'
