Server Exited with Code 1

Your server (or hosting panel) reports that the process exited with code 1. That is a generic non-zero exit meaning Java stopped because something went wrong, it is not the cause itself. The actual error is printed in the lines just above the exit message.

What does this error mean?
When the JVM ends, it returns an exit code: 0 for a clean stop, anything else for a failure. Code 1 simply means the server terminated abnormally. To fix it you must scroll up and read what failed before the process quit. 
Process exited with code 1
Most Common Causes
  • The wrong Java version for your Minecraft version.
  • A typo or invalid value in the JVM flags / start command.
  • The EULA not accepted (eula=false).
  • A corrupt or incomplete server jar.
  • An early crash from a bad config, plugin, or mod.
How To Diagnose
  1. Scroll up in the log: the real error is above the 'exited with code 1' line.
  2. Run 'java -version' and confirm it matches your Minecraft version.
  3. Check eula.txt for eula=true.
  4. Review your start command/flags for typos.
Recommended Fixes
  • Read the error above
    Fix whatever the log reports before the exit line, that is the true cause.
  • Use the correct Java
    Install and point to the Java version your Minecraft release requires.
  • Accept the EULA
    Set eula=true in eula.txt if the server stopped at the EULA check.
  • Validate the start command
    Correct any malformed JVM flags or wrong jar filename.

Frequently Asked Questions

Only that the server stopped abnormally. It is a symptom, the real cause is the error printed above it.

Scroll up, the failure (Java, flags, EULA, jar) is logged before the process exits.

Usually not, code 1 is almost always a startup/config issue, not world corruption.
