android开发记录一个依赖冲突问题

Execution failed for task ':ent:entPdfConvert:generateEntDebugRFile'.
Could not resolve all files for configuration ':ent:entPdfConvert:entDebugCompileClasspath'.
Could not resolve androidx.fragment:fragment:1.5.2.
Required by:
    project :ent:entPdfConvert
    > Cannot find a version of 'androidx.fragment:fragment' that satisfies the version constraints:
         Dependency path 'ent:entPdfConvert:unspecified' --> 'androidx.fragment:fragment:1.5.2'
         Constraint path 'ent:entPdfConvert:unspecified' --> 'androidx.fragment:fragment:{strictly 1.3.6}' because of the following reason: entDebugRuntimeClasspath uses version 1.3.6



Could not resolve androidx.fragment:fragment:{strictly 1.3.6}.
Required by:
    project :ent:entPdfConvert
    > Cannot find a version of 'androidx.fragment:fragment' that satisfies the version constraints:
         Dependency path 'ent:entPdfConvert:unspecified' --> 'androidx.fragment:fragment:1.5.2'
         Constraint path 'ent:entPdfConvert:unspecified' --> 'androidx.fragment:fragment:{strictly 1.3.6}' because of the following reason: entDebugRuntimeClasspath uses version 1.3.6

原因是：entPdfConvert库强制依赖androidx.fragment:fragment的1.3.6版本，而项目里现在又要依赖androidx.fragment:fragment的1.5.2版本，出现了依赖冲突

解决方法：entPdfConvert也改为依赖1.5.2版本或者去掉强制依赖限制，或者项目里改为使用1.5.2版本，反正保持版本一致即可解决问题
