the error message as below:

build.py...
c:\work\edk2\OvmfPkg\OvmfPkgIa32.fdf(118): error 3000: Invalid syntax/format
expected [FD.] near line 110, column 22: TRUE

on my opinion, "expected [FD.]" is not correct

主题: [edk2-devel] [PATCH] BaseTools: Catch the exception in build.py.

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2988

In FDF file, if INF key word is wrongly written as INT,
build tool will report the execption. Build tool should
report the error message.

build.py In order to capture and handle the exception
of fdfparser, the user-defined exception class should
be imported.
