I was using the command given in the index.html included in the mason docs, I was able to build in eclipse once I added all the appropriate jar files to the build path

I cannot speak to Eclipse: it should compile mason fine.  Your javac error below makes perfect sense: there are no files matching mason\*\*.java in the mason repository at all.  They're all deeper in the filesystem tree.  I am afraid that the errors you're getting may be due to some misunderstandings about how to build with Java rather than mason in specific.  You may need to get with someone local who can point you in the right direction.

In eclipse even with the libraries unpacked in to the root src directory I get build errors that look like eclipse can't find the libraries. When using javac from the command line I get  the following error
