d8.bat因找不到java_exe文件，触发EOF

d8.bat中之前代码为：

set java_exe=
if exist    "%~dp0..\tools\lib\find_java.bat" call    "%~dp0..\tools\lib\find_java.bat"
if exist "%~dp0..\..\tools\lib\find_java.bat" call "%~dp0..\..\tools\lib\find_java.bat"
if not defined java_exe goto :EOF

修改后：

set java_exe=
if exist    "%~dp0..\tools\lib\find_java.bat" call    "%~dp0..\tools\lib\find_java.bat"
if exist "%~dp0..\..\tools\lib\find_java.bat" call "%~dp0..\..\tools\lib\find_java.bat"
if not defined java_exe (echo Java.exe not found in the path.goto :EOF
)

运行d8.bat，此段代码，可以看到此段提示

修改find_java.bat路径并拷贝find_java32.exe\find_java64.exe

修改d8.bat中查找find_java.bat路径，并拷贝find_java.bat、find_java32.exe、find_java64.exe到lib路径下。

set java_exe=
if exist    "%~dp0lib\find_java.bat" call  "%~dp0lib\find_java.bat"
if not defined java_exe (echo Java.exe not found in the path.goto :EOF
)

find_java.bat、find_java32.exe、find_java64.exe下载链接如下

find_java.bat :
find_java32.exe
find_java64.exe
