導入項目拋出錯誤

Question

我從這個目錄得到源碼link但它拋出這個錯誤。我已經從github或git獲得了許多源代碼，但大部分沒有得到任何錯誤。但這一次它不是用不同的技巧來解決的。任何幫助將不勝感激

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

Answer 1

我遇到了同樣的問題。我試圖創建路徑，但是當我嘗試構建時它正在被擦除。

我最終從https://f-droid.org/wiki/page/com.android.launcher3抓來源他們還注意到由於protos強制刪除備份而造成的失敗。該源可以直接從https://f-droid.org/repo/com.android.launcher3_1_src.tar.gz

Answer 2

在Launcher3/protos中是一個名爲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"; 

我能夠編譯這個。顯然，這不再是協議緩衝區的更高版本。我不知道副作用，但我能夠編譯，安裝和使用沒有問題。
