    Default Ant

    Hi all,

    I done some Eclipse / Java work today in college, saved it to my usb key and took it home, plugged it in and tried to open Eclipse / Java so that i could continue my work, i am getting a message in a dialog box which say's, "Ant Build" instead of the usual "Java Application".

    Has anyone any ideas on how to resolve this problem ?

    I have also copied some code from another project and tried running it but it is outputting info on as shown below.

    Thanks, Helen

    Usage: javaw [-options] class [args...]
    (to execute a class)
    or javaw [-options] -jar jarfile [args...]
    (to execute a jar file)

    where options include:
    -client to select the "client" VM
    -server to select the "server" VM
    -hotspot is a synonym for the "client" VM [deprecated]
    The default VM is client.

    -cp <class search path of directories and zip/jar files>
    -classpath <class search path of directories and zip/jar files>
    A ; separated list of directories, JAR archives,
    and ZIP archives to search for class files.

    enable verbose output
    -version print product version and exit
    -version:<value>
    require the specified version to run
    -showversion print product version and continue
    -jre-restrict-search | -jre-no-restrict-search
    include/exclude user private JREs in the version search
    -? -help print this help message
    -X print help on non-standard options
    -ea[:<packagename>...|:<classname>]
    -enableassertions[:<packagename>...|:<classname>]
    enable assertions
    -da[:<packagename>...|:<classname>]

    Hi Jos,

    I opened Eclipse / Java as normal, directed the workspace to my usb and chose the file i had been working on earlier today, then i clicked on the GREEN RUN button and the result is what i have attached in my first message. Its no big deal, i could re-write the code, but I would like to know how to resolve or avoid this for when i become a professional Java developer, lol

    regards

    Helen

    Better create a new Java (Application) project in your usual workspace and copy those files over from your usb stick; that way Eclipse can't read any (faulty?) configuration from that stick.

    'It has not worked' doesn't tell us anything. You're basically saying that Eclipse doesn't allow you to create a new Java Application project ...

    Doesn't changing the workspace back again to its original value (or anywhere not on that usb stick) help?
