Re: [wtp-dev] Broken SSE builds due to compilation error, but only in Hudson (can't reproduce locally)
Hi Nick,

I think you also need to adjust the classpath setting for the jre of each project.

Best regards, Lars

John,

Glad you're on board with updating to 1.8.

Here's what *I* would do, because I tend to prefer commandline tools over GUI ones.

1. I would start with piping all the manifest files through sed...

   for m in $(find . -name MANIFEST.MF); do sed -i -e "s#J2SE-1\..#JavaSE-1.8#" -e "s#JavaSE-1\..#JavaSE-1.8#" ${m}; done

2. Run a build to see what breaks with the updated manifests from 1.4, 1.5, 1.6 -> 1.8.

(If you don't like sed, there's prolly a way to do the whole thing in Eclipse, but that'll likely have to be done one plugin at a time.)

3. Then fix all the compilation complaints in Eclipse. 

4. You'll probably also want to bump all your plugins/features from x.y.z to x.(y+1).z to avoid breaking old consumers.

The easiest way for that is to run this:

mvn -Dtycho.mode=maven org.eclipse.tycho:tycho-versions-plugin:1.0.0:set-version -DnewVersion=5.6.7-SNAPSHOT

But bear in mind that it expects ALL plugins/features to be the same version, and if your project doesn't roll that way, it won't bump everything in the reactor in one fell swoop, so you'll have to run it in each and every plugin folder. Or just edit your MANIFEST.MF and pom.xml files by hand.

I agree that we should try and bump the BREE wherever possible. JEE Tools for example seems to still be on a BREE of J2SE-1.5, if we could get that up to 1.8, that would be great.

Nick, what would have to be done to bump up JEE Tools to 1.8?

*wild cheering for dropping support for BREE = J2SE-1.4*

*waves Team Nitin flag* 

If you're keen to break some more eggs, please have a look at https://bugs.eclipse.org/bugs/show_bug.cgi?id=528800re: updating toolchains.xml to the latest JDKs, and maybe removing support for obsolete BREEs like JDK 1.4 - 1.7.

Just a thought!

Nick

I intend to bump up the BREE of both SSE core and UI to 1.8 in the master branch to get us past this once and for all. With the platform dependencies already there, as long as I can keep the code compliance itself where it is (it's more a pragmatic choice than a dogmatic one) I don't see much cause not to.

I've been seeing this for about a week now:

Anyone have time to investigate why this is failing, and offer a fix? I tried to have Hudson ignore the workspace settings files, which worked in the gerrit job but didn't fix the problem in the other jobs.

BTW, are the SSE committers seeing the mail sent to wtp-releng@xxxxxxxxxxx?

Thanks in advance,
