java -target compile

Question

How do I compile a java program in a different version if I have 1.6 and I want it compiled in 1.5? Would it be like...

javac -target1.5 tileGen

But when I do that I get:

error: Class names, 'tileGen', are only accepted if annotation processing is exp licitly requested 1 error

Also, be careful of the difference between the "target" and "source" command line options. "target" specifies the version for the output of the compiler; i.e., the class files. "source" specifies the version for the source code; i.e., the *.java files. I know your error in the above statement is that you left off the ".java" extension, but I think this clarification on the source and target arguments is worth having associated with this question. — Jason

The problem is that javac takes the name of a source file (ending in `.java) not the name of a class.

Try

javac -target 1.5 tileGen.java

instead.

Oh WHOOPS! Rookie mistake. Haha!

Thanks you and digitalsanctum

No problem. It's one of the least helpful error messages I've come across!

Try adding .java to your class name
