Maven error log: http://pastebin.com/ePzuJSvR pom.xml: http://pastebin.com/jdswC9CE We're trying to get Maven working with Jenkins as the frontend, with no luck. The issue: Every library and JAR imports successfully besides the Bukkit API. Without the Bukkit API, the errors found in the log are present and it can't be compiled. All JARs and libraries with the exception of one are hosted on our own server. Using the following script for Maven install: Code (Text): mvn install:install-file -Dfile=bukkit.jar -DgroupId=org.bukkit -DartifactId=bukkit -Dversion=1.9.4-R0.1-SNAPSHOT -Dpackaging=jar I am then calling it appropriately from pom, with no luck. Still receive the errors. I've tried removing Spigot API and keeping just Bukkit as well as vice-versa. I've been trying to solve this for multiple hours now and I'm absolutely stumped. Any ideas?
