How to assert? [message #202957]

Mon, 09 May 2005 10:35

Whenever I try to use assertions I always only get compile errors:
e.g.:
Severity Description Resource In Folder Location Creation Time
2 Syntax error on token "assert", assert expected <java file name,
package, etc. here>

???

Default JRE is a 1.4.2 SDK, Compiler compliance level is set to 1.4.

What else does one need to allow assertions in the source code? Why is
this not working?

This is on eclipse 3.0.1 on WinXP.

assertions don't compile - what am I missing? [message #203265 is a reply to message #202957]

Folks - is this such a complicated question that I don't get an answer
here?

Isn't ANYBODY using assertions? If so, did that person have to enable or
configure anything special to get it working?
I can't believe that I should be the only one, where eclipse refuses to
accept assertions. After all that's a standard Java keyword...

I am completely puzzled why my eclipse 3.0.1 refuses to compile event
the simplest assertion statements, like "assert false;" with an error
message as listed in my original append.

Any help or hint would be appreciated!

you also need to set source and classfile version to 1.4 (default is
1.2/1.3).

i held off replying because it seemed too trivial. I was waiting for your "Found it, never
mind" message. :)

just set the source and classfile compliance to 1.4 and you're done.

Bingo - THAT was the point! I had selected "Compiler compliance level
1.4" but had also checked the "use default compliance settings" checkbox
(and then not paid any further attention to the grayed out settings that
indicate that "Compiler compliance level 1.4" actually means class 1.2
and source 1.3 compatibility and not 1.4 as one (or at least me) would
expect). A bit misleading...

Adjusting that manually - as suggested - did the trick!

Thanks and sorry for this "stupid" question.
