已存在的计划类型:com.google.common.util.concurrent.internal.InternalFutureFailureAccess

Question

我在编译项目时收到此错误.我发现那是因为Guava,以及为什么我得到这个,其他lib也使用Guava(Guava的这个组件)(也许是其他版本,或者只是重复).我找不出哪一个.我正在使用Guava进行散列,同时在记录时保存密码.我知道有必要排除它,但我不知道到底是什么以及如何.

Answer 1

我找到了一个解决方法:只使用'com.google.guava:guava:26.0-android'而不是'com.google.guava:guava:27.0-android'.那问题就没了!

而且,我也希望有人能说出根本原因.

Guava的最新版本（27.0.1：https : //github.com/google/guava/releases/tag/v27.0.1）已解决此问题。只需使用此：

implementation 'com.google.guava:guava:27.0.1-android'
