Whenever I try to create the new 1.8 jar's I keep getting this message towards the end:
^superscript^Exception in thread "main" java.lang.RuntimeException: Error running command, re
turn status !=0: C:\Users\xxxx\Desktop\empty\apache-maven-3.2.3/bin/mvn.bat in
stall:install-file -Dfile=work\mapped.8eb82bde.jar -Dpackaging=jar -DgroupId=org

at org.spigotmc.builder.Builder.runProcess(Builder.java:298)
at org.spigotmc.builder.Builder.main(Builder.java:172)

And after this error it will just stop trying. Please help!!
