Question

我从这个目录link获取源代码，但它抛出了这个错误。我已经从github或git获得了很多源代码，但大多数都没有收到任何错误。但这次不是通过不同的技巧解决。任何帮助将不胜感激

backup.proto:21:8: Option "javanano_use_deprecated_package" unknown.

Answer 1

我遇到了同样的问题。我尝试创建路径但是当我尝试构建时它被擦除了。

我最终从https://f-droid.org/wiki/page/com.android.launcher3获取了源代码。他们还注意到由于protos强制删除备份而导致构建失败的尝试。来源可以直接从https://f-droid.org/repo/com.android.launcher3_1_src.tar.gz

下载

Answer 2

在Launcher3 / protos中是一个名为backup.proto的文件。在文件中：

package launcher_backup;

//option javanano_use_deprecated_package = true; >>> remark this line out.
option java_package = "com.android.launcher3.backup";
option java_outer_classname = "BackupProtos";

我能够编译它。显然，这不再是协议缓冲区的更高版本。我不知道副作用，但我能够编译，安装和使用没有问题。
