Bug 106057 – unable to recompile xerces, because of circular dependency with xerces and ant.

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Rune Schjellerup 2005-09-15 05:49:03 UTC]

If xerces somehow ends in a state where it doesn't work, then the
circular dependency with xerces using ant and ant using xerces,
makes it troublesome to recompile xerces.

I realize that the problem in this case is my own doing, since I mix 1.4 and 1.5
VMs. I presume I must have emerged xerces while suns 1.5 VM was set.
But for less experienced users I imagine this kind of problem is hard to fix.



Reproducible: Always
Steps to Reproduce:
1. switch to suns 1.5 VM
2. emerge xerces
3. switch to blackdown 1.4.2
4. any ant build will fail, including trying to reemerge xerces.

Actual Results:

Expected Results:  
This is actually what I would expect, but one could hope for a bit more help on
how to fix it.

[Comment 1 Petteri Räty (RETIRED) 2005-09-15 06:01:56 UTC]

Remove everything java you have installed and start again with the 1.4 jdk. The
byte code produced by the 1.5 compiler is not compatible with 1.4 so as you said
this is your doing. We are currently testing the solution to the 1.5 problem and
until then the 1.5 jdk stays package.masked. So do not set 1.5 as the system vm
and next time please think twice when filing bugs about package.masked packages.
If you want to help out testing, please join #gentoo-java and contact axxo or
see one of the 1.5 metabugs for more info.
