General

When I try to compile the widgetset or theme fail but without any error or crashes simply doesn’t do anything.

I see an exception on workspace log:

Same issue, recently upgraded to Eclipse Mars 64 bit, JDK 1.8 build 91, Vaadin 7.6.6. Any straightforward fixes for this? I’ve read about several fixes involving moving the project and/or the JRE, but is there a simple fix?

Here is the source branch if you want to give it a try:

I have used “Long Path Tool” in this situation and it helped me easily and quickly. This tool can fix all the error messages like:

  1. Path too long
  2. Cannot delete file: cannot read from source file or disk
  3. Cannot delete file: Access is denied
  4. There has been a sharing violation.
  5. The source or destination file may be in use.
  6. The file is in use by another program or user.
  7. The file name you specified is not valid or too long. Specify a different file name.

and all other related error messages.
I hope you will find this solution helpful and don’t forget to leave your comments.
