How to get JavaC to maintain good class files if some input files do not work?

Question

When compiling two independent java files with one javac call, their class files either

• both are output to the output folder, upon successful compilation or

• no class file is output if one source file contains some syntax or another error.

How can we get JavaC to keep a good class file?

In other words, how can we make Javac behave in the best way?

Answer 1

I would go with:

• Javac multiple call package
• Use another compiler, for example, Eclipse.

As far as I can tell, failOnError will not work as a flag for javac - only if you use Ant.
