AOSP構建錯誤：EXECUTABLES/iw_intermediates/version.c

Question

幾天前我做了一個AOSP build 7.1.1，它運行良好。今天，我決定做一個乾淨的版本（make clean）並開始工作。之後，當我在一段時間後嘗試編譯make otapackage時，它給了我下面的錯誤。

[ 44% 7552/17136] build out/target/product/hikari/gen/EXECUTABLES/iw_intermediates/version.c 
FAILED: /bin/bash -c "external/iw/version.sh out/target/product/hikari/gen/EXECUTABLES/iw_intermediates/version.c" 
fatal: No names found, cannot describe anything. 
ninja: build stopped: subcommand failed. 
build/core/ninja.mk:148: recipe for target 'ninja_wrapper' failed 
make: *** [ninja_wrapper] Error 1 

#### make failed to build some targets (01:39:34 (hh:mm:ss)) #### 

每次都是一樣的。任何解決方案

它試圖檢查git版本號時失敗。 內外部/ IW/version.sh，它失敗當它到達：

descr=$(git describe --match=v*):

if [ -d .git ] && head=`git rev-parse --verify HEAD 2>/dev/null`; then 
     git update-index --refresh --unmerged > /dev/null 
     descr=$(git describe --match=v*) 
     # on git builds check that the version number above          
     # is correct...                   
     [ "${descr%%-*}" = "v$VERSION" ] || exit 2 

     v="${descr#v}" 
     if git diff-index --name-only HEAD | read dummy ; then 
       v="$v"-dirty 
     fi 
else 
     v="$VERSION" 
fi 
echo '#include "iw.h"' > "$OUT" 
echo "const char iw_version[] = \"$v\";" >> "$OUT" 

我有同樣的問題，有兩種方式去了解它：

1. You can comment out everything except v="$VERSION" and the last two echo lines.But this is a temporary fix.

2. Another way to solve this is by doing a repo sync before you execute make. I fixed it by simply doing a repo sync and that updated and fixed everything for me.
