Errors running builder 'Google WebApp Project Validator'

Error:

Problems occurred building the selected resources.
Errors running builder 'Java Builder' on project 'curve_app'.
com/google/gdt/eclipse/suite/preferences/GdtPreferences
Errors running builder 'Google WebApp Project Validator' on project 'curve_app'.
java.lang.NullPointerException

Workaround solution:

Close all projects, close eclipse.

Start eclipse using, "eclipse -clean" option.

You can try repeating the process 2-3 times,  if it does not work first time.

Not sure of the exact reason why this appears.

Turbogears debugging in Eclipse

Setting up debug enabled environment for a Turbogears application in Eclipse is not really straightforward. I struggled a lot before I could set it up. Initially I wasnt even sure if I could set up break points and debug the application like in microsoft visual studio. It is very much possible although some of the things are not very obvious. Here is a list of things to check up, if you are facing problems.

1. You can install Pydev by following the instructions mentioned on pydev website. You can also have a look at this ibm site which helps you make the necessary settings in Eclipse.

2. You can patch the Decorators file from pydev blog. If you are facing any problems drop your email id I will send you the patched file.

3. Pydev gives problems with certain turbojson package versions. You may try to downgrade and install a previous version of turbojson package. Use the following command to do so:
>easy_install -U turbojson==1.1.4

>easy_install -U DecoratorTools==1.4 

4. Remember, you will still see the following error when you start the debug session.

PYDEV DEBUGGER WARNING:

sys.settrace() should not be used when the debugger is being used.

This may cause the debugger to stop working correctly.

If this is needed, please check:

to see how to restore the debug tracing back correctly.

Call Location:

  File "C:\Python24\lib\site-packages\decoratortools-1.4-py2.4.egg\peak\util\decorators.py", line 562, in uninstall


But, wait for a few seconds and eclipse will start the debug session after the error message.
