没有这样的属性:class:org . grad le . API . tasks . output file的ABI

Question

我对React Native的开发是全新的。我开发了一个小项目，并希望有一个释放APK。但是我会在发布版本上堆栈。有人能帮我吗？谢谢你。

错误是

没有这样的属性:org . grad le . API . tasks . output file org . grad le . API . projectconfigurationexception:配置项目时出现问题':app '原因:groovy . lang . missingpropertyexception:没有这样的属性:org . grad le . API . tasks . output file

Answer 1

在 build.gradle（：app） 中替换此行

def abi = output.getFilter(OutputFile.ABI)

与：

def abi = output.getFilter(com.android.build.OutputFile.ABI)

Answer 2

好吧，我找到了解决方案。正在添加

import com.android.build.OutputFile

到构建。gradle（应用程序）解决了这个问题
