pkg文件中的error: file I/O fault 错误

如果将一个已有工程导入到Carbide中，或者clean的时候没有清理干净，有可能出现这种错误。类似：

***Invoking makesis.exe ....

C:/Symbian/9.1/S60_3rd/epoc32/tools/makesis.exe
C:/Symbian/workspace/DemoOne/sis/_resolvedDemoOne_S60_3_X_v_1_0_0.pkg
C:/Symbian/workspace/DemoOne/sis/DemoOne_S60_3_X_v_1_0_0.sis -v
Processing C:/Symbian/workspace/DemoOne/sis/_resolvedDemoOne_S60_3_X_v_1_0_0.pkg...
C:/Symbian/workspace/DemoOne/sis/_resolvedDemoOne_S60_3_X_v_1_0_0.pkg(27) : error: file I/O fault.
***Non-Zero Status: makesis.exe returned with exit value = 1

在d:/Symbian/9.1/S60_3rd_MR_2/epoc32/build/Symbian/workspace/NetTest/group目录，将里面的内容删除，再重新build，可解决此问题。
