Problem in compile nutch8.1

[fa...@gzedu.gov.cn]

As nutch8.1 has no parse-rtf and parse-mp3 plugins by default, so I use Eclipse SDK Version: 3.2.1 to compile nutch81 in order to add some plugins .

Curiously Eclipse SDK Version can build parse-html and other plugins with no problems , but when building parse-rtf and parse-mp3, it says:

for parse-rtf :
