Hey there, I'm trying to run the spigot BuildTools as a Job on my Jenkins CI Server. I've tried to execute the jar file with this command (Note: I'm on a Windows Server so I'm calling the sh.exe from git for Windows, even though it also should work without the sh.exe): Code (Text): sh --login -i -c "curl -z BuildTools.jar -o BuildTools.jar https://hub.spigotmc.org/jenkins/job/BuildTools/lastSuccessfulBuild/artifact/target/BuildTools.jar && java -jar BuildTools.jar" If I execute the above command in the git bash for Windows it executes without a problem and my spigot.jars are being built. I can even run the command on a normal cmd or PowerShell window and it runs without a problem. But if I execute the command (with or without the sh.exe) in Jenkins the build process always gets stuck at this annoying error Spoiler: Error Attempting to build Minecraft with details: VersionInfo(minecraftVersion=1.8.3, accessTransforms=bukkit-1.8.3.at, classMappings=bukkit-1.8.3-cl.csrg, memberMappings=bukkit-1.8.3-members.csrg, packageMappings=package.srg) Starting download of https://s3.amazonaws.com/Minecraft.Download/versions/1.8.3/minecraft_server.1.8.3.jar Downloaded file: work\minecraft_server.1.8.3.jar with md5: cdd49c262cb98db636b8fae2837869ef Final mapped jar: work\mapped.73f3c166.jar does not exist, creating!
