Hi,

I tried to start a server on skyfactory 2.5. but when I started it it showed a error. I don't know what to do so if anyone can help me please? If I use server 2.5.0 everything works but if I use 2.5.5 the latest than I get this error and I want to use 2.5.5

Code:
Starting server

I think we need more info. What is the OS and what are you using to start the server? When you updated the server did you also update the jar files used and the startup script?

I use windows server 2012 R2, I installed Java 8 111 (64-bit), I downloaded the server from the ftb launcher and to start it's a .bat and inside it it's this code

Code:
@if NOT "%FTB_VERBOSE%"=="yes" (
    @echo off
)

call settings.bat

if NOT EXIST minecraft_server.1.7.10.jar (
    goto install
)
if NOT EXIST libraries\%LAUNCHWRAPPER% (
    goto install
)
goto skipinstall

:install
echo running install script!
call FTBInstall.bat
:skipinstall

REM Check if java in path
REM TODO: use %JAVACMD%
where java > NUL 2>&1

if %ERRORLEVEL% NEQ 0 (
    echo No java binary in path. Can't run server, exiting...
    pause
    exit /B
)

REM Test JVM
REM e.g. 32-bit JVM does not have server\jvm.dll library
java -server -version > java-test.log 2>&1

if %ERRORLEVEL% NEQ 0 (
    echo Detected following JVM error:
    echo =======================================
    more java-test.log
    echo =======================================
    echo JVM test failed. Can't run server, Exiting...
    pause
    exit /B
)

if not exist eula.txt (
    echo Missing eula.txt. Startup will fail and eula.txt will be created
    echo Make sure to read eula.txt before playing!
    goto startserver
)

find "eula=false" eula.txt 1 > NUL 2>&1
if %ERRORLEVEL% EQU 0 (
    echo Make sure to read eula.txt before playing! Exiting.
    pause
    exit /B
)

del /f /q autostart.stamp > nul 2>1

:startserver
echo Starting server

:server_loop
if exist autostart.stamp (
    del /f /q autostart.stamp > nul 2>1
    echo If you want to completely stop the server process now, press Ctrl+C before the time is up!
    for /l %%i in (5,-1,1) do (
        echo Restarting server in %%i
        choice /t 1 /d y > nul
    )
    echo Starting server now

    echo Server process finished
    goto :server_loop
)
echo Exiting...
pause
I don't know if you need more?

As a test can we eliminate the script? Open a command prompt and use the CD command to go where your FTBServer-1.7.10-1614.jar file is located. Then type in the followig:
Code:
java -server -Xms512M -Xmx4096M -jar FTBServer-1.7.10-1614.jar nogui
If it produces and error capture as much of the console you window you can and post it here. I'm not trusting some of those command line arguments for Java since I know they only work in Java 7.

I followed the steps and this is what i found.. I don't know if I did it right so let me know..

Looks correct. Let me do some testing at home later tonight to see if I can duplicate this error. I don't have a windows server but I'll try it on my windows 10 box and see what I get.

One last thing can you type in java -version on the command line. I just want to make sure I'm duplicating with that exact same version.

Thnx for helping man!

Code:
C:\ftb\server\FTBPresentsSkyfactory25Server>java -version
java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)

Ok so I get the exact same thing using a fresh download of the server on Java 1.8.0_101 64 bit. The StartServer.bat isn't calling the FTBInstall.bat. So drop to the command promt again CD to the same directory and type in FTBInstall.bat. Once that is done run the normal ServerStart.bat and that should fix your issue.

The FTBInstall.bat downloads the minecraft libraries directly from mojang.
