When running the command "java jar BuildTools.jar -rev 1.17" in GitBash it will not build the spigot 1.17 jar file and comes up with the following error at the end:

'cmd' is not recognized as an internal or external command,
operable program or batch file.
Exception in thread "main" java.lang.RuntimeException: Error running command, return status !=0: [C:\Users\PC\Desktop\BuildTools\apache-maven-3.6.0/bin/mvn.cmd, -Dbt.name=3149, install:install-file, -Dfile=work\bukkit-e3c5450d-fields.csrg, -Dpackaging=csrg, -DgroupId=org.spigotmc, -DartifactId=minecraft-server, -Dversion=1.17-R0.1-SNAPSHOT, -Dclassifier=maps-spigot-fields]
