在文件夹中搜索jar文件的最新版本，然后从批处理文件运行它

Question

I created a simple batch file to run jar server file. It is two lines of code:

cd /D %~dp0
java -jar server-0.17.0.jar

The problem is the server file is updated every while and hence script either fails to run the correct version or fail to run.

My request is, is there anyway to replace server jar file with latest released by number or date dynamically?

I'm only aware that I can retrieve available jar files using:

dir *.jar

But have no idea how to concatenate the command with the katest version. Thanks

Answer 1

you can try a script like this:

@echo off
for /f "delims=" %%x in ('dir /od /b server*.jar') do set latestjar=%%x
java -jar %latestjar%

Second line in this script will set the latestjar to the last created file whose name compliant with server*.jar template.
