Ant

[helen1974]

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

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

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.

kind regards,

Jos

I tried that, but it has not worked, but thanks for the help and suggestions.

'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 ...

kind regards,

Jos

yes, Jos, thats what I am saying, maybe I need to uninstall and reinstall Eclipse ?

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

kind regards,
