已有工程是在CCS5.5上完成的，由于我现在是win10系统，用的是CCS v8系列，在安装mcsdk后，打开工程文件进行mcsdk添加时出现以下错误
具体内容如一下所示：
An error occurred while collecting items to be installed
session context was:(profile=epp.package.cpp, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
Problems downloading artifact: osgi.bundle,com.ti.rtsc.NDK.product_2.21.1.38,2.21.1.38.
File has invalid content:C:\Users\jeffrey\AppData\Local\Temp\signatureFile4654884782450952914.jar
Invalid content:plugin.xml
The file "plugin.xml" in the jar "C:\Users\jeffrey\AppData\Local\Temp\signatureFile4654884782450952914.jar" has been tampered!
望各位专家解答一下
