Question

我正在尝试构建我的应用，但会弹出以下错误。几天前，我对构建它没有任何问题。

Error       The "CheckDuplicateJavaLibraries" task failed unexpectedly.
System.IO.FileNotFoundException: Could not find file 'obj\Debug\__library_projects__\VectorCompat\library_project_imports\bin\classes.jar'.

我应该删除VectorCompat组件并重新添加吗？为什么它在几天前建好时会突然出现这个错误？

提前致谢。

似乎有些文物未被复制到您的obj文件夹，即VectorCompat的{{1}}。我建议手动删除classes.jar文件夹并重建解决方案。
