Hello, thanks for taking the time to see my problem, try many ways and just do not manage to fix it on my own, I need your help, I'm sure it is my PC, please your help would be appreciated. I have, java 8 least update, and JDK least update, And I think the most recent version of spigot - MC 1.12, And I'm sorry, I can not put the exact version in which I have, the server stops working before I can place a command, but I remember compiling it about two days ago (works on other PCs), I'm sure it's not my spigot, In fact if I use a version like the 1.9 there is the same problem but the server doesn't stop, I think I missed something, I'm an old user of Mc, who come back to have a good time _C:\Users\z7\Desktop\Server>java -Xmx1G -jar spigot.jar -o true Loading libraries, please wait... java.lang.NoClassDefFoundError: Could not initialize class org.fusesource.jansi.WindowsAnsiOutputStream at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at org.apache.logging.log4j.core.appender.ConsoleAppender.getOutputStream(ConsoleAppender.java:263) at org.apache.logging.log4j.core.appender.ConsoleAppender.getDefaultManager(ConsoleAppender.java:226) at org.apache.logging.log4j.core.appender.ConsoleAppender.createDefaultAppenderForLayout(ConsoleAppender.java:172) at org.apache.logging.log4j.core.config.AbstractConfiguration.setToDefault(AbstractConfiguration.java:581) at org.apache.logging.log4j.core.config.DefaultConfiguration.<init>(DefaultConfiguration.java:47) at org.apache.logging.log4j.core.LoggerContext.<init>(LoggerContext.java:86) at org.apache.logging.log4j.core.selector.ClassLoaderContextSelector.createContext(ClassLoaderContextSelector.java:171) at org.apache.logging.log4j.core.selector.ClassLoaderContextSelector.locateContext(ClassLoaderContextSelector.java:145) at org.apache.logging.log4j.core.selector.ClassLoaderContextSelector.getContext(ClassLoaderContextSelector.java:70) at org.apache.logging.log4j.core.selector.ClassLoaderContextSelector.getContext(ClassLoaderContextSelector.java:57) at org.apache.logging.log4j.core.impl.Log4jContextFactory.getContext(Log4jContextFactory.java:147) at org.apache.logging.log4j.core.impl.Log4jContextFactory.getContext(Log4jContextFactory.java:45) at org.apache.logging.log4j.LogManager.getContext(LogManager.java:194) at org.apache.logging.log4j.LogManager.getLogger(LogManager.java:551) at org.apache.logging.log4j.LogManager.getLogger(LogManager.java:537) at net.minecraft.server.v1_12_R1.MinecraftServer.<clinit>(MinecraftServer.java:55) at org.bukkit.craftbukkit.Main.main(Main.java:194)_
