Update from develop and cannot start...



  • Hi all, I did a pull this evening to build and update my jar, to check the latest awesomeness, but now I cannot start my poor server. I have backups and all, so there is no catastrophe here. But I would like to know what the problem is.

    The bottom of the log says:

  • ADMIN

    You can visit this. https://github.com/mycontroller-org/mycontroller/issues/362

    However, we have up to date SNAPSHOT version available at http://forum.mycontroller.org/topic/58/download-snapshot-build



  • Hi , I am actually building from source, and just copying the jar file. It has worked many times with the below script. Maybe you can have a look and decide if that is a stupid approach, considering data migrations, configuration file changes etc....??

    # goto home directory
    cd
    
    # stop the server and wait for it
    ./Desktop/mycontroller/bin/stop.sh
    sleep 10
    
    # take a backup just in case
    cp -a mycontroller mycontroller_backup
    
    # assuming repository present and pulling latest source
    cd Desktop/clonse/mycontroller
    git pull
    
    # build it from source
    mvn package
    
    # copy jar file and start server
    cp -r dist/target/*single.jar /home/$USER/Desktop/mycontroller/lib
    cd
    ./Desktop/mycontroller/bin/start.sh

    • Do not copy original-my controller-dist-standalone-0.0.3.Final-SNAPSHOT-single.jar
    • copy only mycontroller-dist-standalone-0.0.3.Final-SNAPSHOT-single.jar, delete all other jar files on /home/njb/Desktop/mycontroller/lib/
