Hi,

Eclipse doesn't allow one to set the class compilance to 1.4 and the
source compilance to 5.0, until today I thought this is perfectly the
right thing, but then found out that I can use 5.0 features and still
compile to 1.4 source level or do I read the following article in a
wrong way:

http://www-128.ibm.com/developerworks/java/library/j-jtp0227 7.html

Why is it somehow possible to use the undocumented -target jsr14 feature
in eclipse's compiler settings? I already read
http://www.masutti.ch/eel/ and ask myself why eclipse doesn't support
this setting out of the box?

This settings doesn't allow you to emulte all 1.5 features (no enums, no
for each statements). It makes more sense to actually get 1.5 .class
files if you are using 1.5 features.

Hi Olivier,

I know but I can easily live without these features. What I want are
things like generics which are compatible with 1.4 class files, if you
are a library developer like I am and want to provide an API using
generics but also support 1.4.

If eclipse doesn't allow me to the set .cass level and export my files
using the export wizard. I need to write my own build.xml to make this
happen, for unit-testing it's the same, ... .

Isn't it acceptable to add the jsr14 to the list of .class-File options?

I haven't tried this setting. I'll see if this is possible.
