Re: [cross-project-issues-dev] Is there a reason to have org.apache.commons.logging 1.0.4 in the platform?


Looking in the httpclient page :
"Commons HttpClient 3.x codeline is nearing the end of life. All users of Commons HttpClient 3.x are strongly encouraged to upgrade to HttpClient 4.0."

looking at the dependencies, the last 4.0.1 comes with commons-logging 1.1.1 :)

Scott Lewis a écrit :
FWIW, Pascal and John A indicated, ECF is using the apache httpclient (3.1) and this dictates a dependency on commons logging 1.0.4. We (ECF, etc) would be completely willing to move some other mutually agreed upon version of commons logging, but there are some important subtleties: Since it's httpclient that depends upon 1.0.4, once a replacement version of commons logging was selected, someone would have to look for/test for regression in httpclient 3.1 in order to do so...since there's unfortunately no guarantee that httpclient 3.1 doesn't have a hard dependency on 1.0.4 (I'm not saying there is or anything...just that we don't know, and discovering something like that could be dramatically bad if the change was done cavalierly...especially this late in the game).

All this by way of saying...I think aligning on a version would be fine (I mean...other than the version upon which we're aligned now)...but it's unfortunately not trivial for us to safely change this dependency...particularly without some available resource to check/test for possible regression.

This topic (commons.logging 1.0.4 being supplied and other projects needing 1.1) has also cost me several hours and many builds. I would not be surprised if it also cost others a few hours (so we talk about mandays of work).

So from my point of view it would be great if Eclipse projects can align on the version used for such a base jar file as commons.logging....

This is being brought in by org.apache.commons.httpclient which is used by p2 (through ECF) Do you know if they are compatible with each others? Did you try running with just the 1.1 version? Remember that at Apache, version numbers don't necessarily have the same semantics than eclipse. Actually worse, ppl just bump versions without really thinking.

At this point p2 ships 1.0.4 because we don't know any better. However given all the problems we have had around transports in p2 and the time it took us to stabilize I'm really not inclined to change that just for source issues of a third party bundle.

I noticed that many projects depend on o.a.c.logging 1.1.x+ while the platform still includes 1.0.4. That causes duplicate bundles and some build problems regarding the respective source bundles. Would it be possible to agree on a common version?
