步驟2：

為了讓ant能執行make，還得用指令碼實現

linux sh指令碼實現,build.sh:

#!/bin/sh

export BUILD_FOLDER="`cd "$(dirname "$0")"; pwd`.prj"
## 判斷Makefile是否存在，如果不存在，則呼叫newprj.sh生成Makefile
if [ ! -r "$BUILD_FOLDER/Makefile" ]
then 
    ./newprj.sh
fi

cd $BUILD_FOLDER
# 執行clean 清除已經有編譯生成的檔案
make clean
# make編譯
make

windows bat指令碼實現,build.bat:

ECHO OFF
SET BUILD_FOLDER=%cd%.prj
IF not exist "%BUILD_FOLDER%/Makefile" call newprj.bat
pushd "%BUILD_FOLDER%"
make clean
make
popd

上面兩個不同的指令碼實現的功能類似，區別只是在不同的平臺上執行，實現make clean和make的動作。

步驟3：

有了步驟2中的build.sh/build.bat，就可以在ant指令碼中呼叫它們實現專案編譯了。
