Retiring the ANT/JAVA build and removing the older EDK II packages that required ANT/JAVA.
Last Ant/Java build was r7166
Developers requiring the Java/Ant packages should checkout the branch from:
https://edk2.tianocore.org/svn/edk2/branches/AntJava
git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@7168 6f19259b-4bc3-4df7-8a09-765794883524

-Routine Description:
- Given the input key, search for the next matching file in the volume.
-
-Arguments:
- This - Indicates the calling context.
- FileType - FileType is a pointer to a caller allocated
- EFI_FV_FILETYPE. The GetNextFile() API can filter it's
- search for files based on the value of *FileType input.
- A *FileType input of 0 causes GetNextFile() to search for
- files of all types. If a file is found, the file's type
- is returned in *FileType. *FileType is not modified if
- no file is found.
- Key - Key is a pointer to a caller allocated buffer that
- contains implementation specific data that is used to
- track where to begin the search for the next file.
- The size of the buffer must be at least This->KeySize
- bytes long. To reinitialize the search and begin from
- the beginning of the firmware volume, the entire buffer
- must be cleared to zero. Other than clearing the buffer
- to initiate a new search, the caller must not modify the
- data in the buffer between calls to GetNextFile().
- NameGuid - NameGuid is a pointer to a caller allocated EFI_GUID.
- If a file is found, the file's name is returned in
- *NameGuid. *NameGuid is not modified if no file is
- found.
- Attributes - Attributes is a pointer to a caller allocated
- EFI_FV_FILE_ATTRIBUTES. If a file is found, the file's
- attributes are returned in *Attributes. *Attributes is
- not modified if no file is found.
- Size - Size is a pointer to a caller allocated UINTN.
- If a file is found, the file's size is returned in *Size.
- *Size is not modified if no file is found.
-
-Returns:
- EFI_SUCCESS - Successfully find the file.
- EFI_DEVICE_ERROR - Device error.
- EFI_ACCESS_DENIED - Fv could not read.
- EFI_NOT_FOUND - No matching file found.
- EFI_INVALID_PARAMETER - Invalid parameter
