Ant compc swc compile Error: ‘Class’ is undefined.

In making an Ant script to produce a swc of my project, I used the compiler.external-library-path to include an external swc. I forgot to include append=”true” and this killed the include of the needed flex swcs.

If you start getting lots of these errors that seem like the Flex/Flash basics aren’t compiling in, look for the swcs you’ve included and make sure you append them, not overwrite.

Here’s the errors I got, there’s a lot of them, but maybe this will help people find this information by searching:
