Job failed, see logs for details

Answer 1

錯誤：任務'：app：transformClassesAndResourcesWithProguardForRelease'的執行失敗，意味着您在發行版中使用了proguard。

嘗試將build.gradle文件中的minifyEnabled選項設置為false。

像這樣：

buildTypes {
        release {
            minifyEnabled false
            ...
        }
    }

Answer 2

如果您制作的應用仍在運行

minifyEnabled false

那么您必須手動忘記使用-dontwarn發出的每個警告

示例： -dontwarn java.lang.invoke.**
