Eclipse 3.3.1 does not generate java1.5 class files [message #325510]

Hi ,

I have build eclipse 3.3.1.1 with Java 6.0 on HP-UX. When I try to
generate a class file with this eclipse with preference for java
compliance set to 5.0 , it not generating 5.0 class files. Its
generating 6.0 class files.

Do we need to do any special configuration changes to make this working?

Thanks
Gowri

You might have overridden the global settings in your Project

The compliance level works in other platforms ( Linux / Windows).
I have issue with the eclipe IDE that I built on HP-UX. Do we need to
update the config.ini file to make this working ?

So your problem is that PDE-build doesn't respect your compilance
settings right? You need to set a target environment in your MANIFEST.MF
this is used to inform the PDE-build which compilance level has to be used.

Could you please explain your solution. Do we need to change manifest file
in project level or Eclipse level. I checked the MANIFEST.MF file in the
eclipse/plugins/org.eclipse.pde.build_3.3.1.v20070828/META-I NF
This has " Bundle-RequiredExecutionEnvironment: J2SE-1.4 "

Well I think PDE uses the information present in the MANIFEST.MF of the
plugin it builds. If no information is found there it runs the compiler
with no information and if you are on a JDK-6 system the default
..class-Format created by PDE-builds will be 1.6.

The simplest solution would be to simply tell eclipse to use another
JDK. I'm not 100% sure about all this but I think I can remember that
PDE doesn't respect compiler settings defined in the
project-preferences. Maybe someone with more knowledge about PDE can
give a better answer.

If you're bundle is intended to run on 5.0 and higher, it should be
J2SE-1.5. PDE Build uses the first BREE entry to decide what to
build/compile on plug-in export.
