TM4C123GH6PM编译错误

错误是这样的
js: "C:/ti/xdctools_3_32_01_22_core/packages/xdc/tools/Cmdr.xs", line 52: Error: xdc.tools.configuro: Error: no target named: please use -t, -b, or --cb
gmake: *** [build-547906065] Error 1

而且在properties中出现这个问题
上面写着：None of the currently selected products supplies value for the Target.Please specify the Target manually,or try using a pre-3.30 version of XDCtools.
try using a pre-3.30 version of XDCtools这个建议我也试过了

项目以前是使用ccs6.1.1开发的，编译器当时是用TI v5.2.7，TivaWare_C_Series-2.1.1.71
现在是用ccs6.2.0 编译器用TI v 5.2.9  TivaWare_C_Series-2.1.1.71一样
也已经试过重建创建文件，没有用，还是这个问题。
已经为这个问题折腾整整两天了，周边的朋友也没有遇到这个问题，恳请有相同经历的朋友帮助一下，不胜感激！
问题有点长
