[Soot-list] How to set -process-dir and -cp correctly in this case? I got the error: class small.DataClass read in from a classfile in which DataClass was expected.

[Bodden, Eric]

Hi Khanh.

When you set Soot's classpath or process dir then the path must always point to the root of the package hierarchy, not to some particular package folder, i.e., in your setting it must point to C:\test\bin\
You can then the include/exclude options to include/exclude certain packages from analysis. See here:
http://www.sable.mcgill.ca/soot/tutorial/usage/index.html

Does that work for you?


Cheers,
Eric

So now the file structure is identical. But I got the error instead("class small.DataClass read in from a classfile in which DataClass was expected.")

> But, even with only "small" under C:\test\bin, I cant do -process-dir C:\test\bin -cp C:\test\bin\small, either (Soot will complain there is no small.DataClass on classpath- why? now -cp only see DataClass.class?)
