Using assert with Eclipse compiler [message #108468]

Tue, 21 October 2003 22:51

Eclipse User

I am trying to use assert with the Eclipse M4 compiler and the Sun JDK
1.4.2.

I have set the following options for the compiler
Compiler compliance level 1.4
Generated .class file compatibility 1.4
Source compatibility 1.4
Report 'assert' as identifier Error

However with these settings all uses of assert are flagged as errors. What
else do I need to do to get asserts going?

Regards

When I try to do this Eclipse gives an error message at the top of the
preference page stating
"When source compatibility is 1.4. 'assert' cannot be an identifier".

That's what started this query as I had already tried this. Is this a bug
then?

Sorry, I misread your settings. In Source 1.4 compatibility, 'assert' cannot
be used as an identifier (e.g. for a local variable name). So it can only be
reported as an error if this is the case.

So with the the following settings:
Compiler compliance level 1.4
Generated .class file compatibility 1.4
Source compatibility 1.4
Report 'assert' as identifier Error

I'm able to compile the following class:
public class X {
void foo() {
assert true;
}
}

but this fails to compile (as expected since 'assert' is used as an
identifier):
public class X {
void foo() {
boolean assert = true;
}
}

Do you have a case where you use 'assert' as the 'assert' keyword and this
fails to compile?
If you do, please fill a bug report against JDT/Core.

Unfortunately, with those settings I am not able to compile
public class X {
void foo() {
assert true;
}

Is it possible that honouring assert is also tied into one of your internal
DEBUG specifications that has been left in inadvertently?
I.E. one of those debug variables that must also be set that some Eclipse
people use during early release of a new capability.

I am encountering this problem on every machine that I try this.

Are you sure that you don't have a different compiler setting for the
project in which you compile this source. You can define compiler
settings per project and maybe this is the problem in your case.
I tried Jérôme example with Eclipse M4 and it worked.

I will have to check this when I get home. At work when I tried it I was
able to get it to work.
