Re: Compiler incompatibility?

The ANT javac task uses the JDK compiler. You must use a 1.4 version of
the JDK I guess.
The Eclipse project in the other hand uses the Eclipse compiler, which
must be set to 5.0 compliance level I guess.
Every time you save a .java file in your project it automatically
rebuild with the Eclipse compiler.
But when you start the execution of the ANT script in your project or
from the command line you use the JDK compiler and it can lead to
dependent .class files mismatch.
Two questions to be answered first:

1- In Eclipse:
From the menu: 'Window' / 'Preferences...'
In the window, left side: expand 'Ant' then click on 'Runtime'
On the right side: expand 'Global Entries'
*** What do you see? Do you have a tools.jar in it? Does it come from a
JDK 1.4? Else? ***

Yes, I have a tools.jar, specifically D:\Java\jdk1.5.0_06\lib\tools.jar.

2- In Eclipse:
From the Package Explorer window: right-click on your project then
select 'Properties'
In the window, left side: click on 'Java Compiler'
*** On the right side, what is the compiler compliance level? ***


All of the JDK Compliance section is greyed out ("Enable project specific
settings" is NOT checked). However, but the compiler compliance level is
clearly 5.0. By the same token, in Windows/Preferences/Java/Compiler,
Compiler Compliance level is 5.0 and "use default compliance settings" is
checked.

Also, the value of the compiler parameter in my Ant javac task is "modern".
