奇怪的问题！（android-sdk-windows）

Question

注意我用红色标注的地方。
正常运行命令的时候就显示x86，通过android的脚本就多出个符号。
脚本是android.bat

1. for /f %%a in ('%java_exe% -jar libarchquery.jar') do set swt_path=lib%%a
3. if "%1 %2"=="update sdk" goto StartUi
4. if not "%1"=="" goto EndTempCopy
5. :StartUi
6. echo [INFO] Starting Android SDK and AVD Manager
8. rem We're now going to create a temp dir to hold all the Jar files needed
9. rem to run the android tool, copy them in the temp dir and finally execute
10. rem from that path. We do this only when the launcher is run without
11. rem arguments, to display the SDK Updater UI. This allows the updater to
12. rem update the tools directory where the updater itself is located.
14. set tmp_dir=%TEMP%temp-android-tool
15. xcopy %swt_path% %tmp_dir%%swt_path% /I /E /C /G /R /Y /Q > nul
